| 1 | Variations of organic carbon isotopic composition and its environmental significance during the last glacial on western Chinese Loess Plateau显示文摘A high-resolution loess section in the western Chinese Loess Plateau, Yuanbao Section, was sampled for organic carbon isotopic analyses. The soil organic carbon isotope (δ13Corg) varied be- tween ?22.6‰ and ?27.5‰ during the last glacial at the section. During the last interstadial, the δ 13Corg values were more negative than those in both early and late periods of the last glacial by 4‰. The iso- topic composition indicates a coupled response of the pure C3 plants to the temperature, precipitation and the concentration of atmospheric CO2. Decrease in temperature and the atmospheric CO2 concentration from the last interstadial to Last Glaicial Maximum (LGM) caused the organic carbon isotopes to be- come positive by 1.5‰―2.0‰. The amplitude of 4‰ in the δ 13Corg variation during the last glacial should be mainly caused by the precipitation change. Therefore, the δ 13Corg variations of the Yuanbao Section during the last glacial period documented the large-amplitude fluctuation of the monsoon precipita- tion, which is estimated to be 250―310 mm more during the last interstadial than that in the LGM, and 100 mm more than that during early last glacial. The rapid changes of the monsoon precipitation on mil-lennial scale during the last glacial have also been recorded in the isotopic variations in Yuanbao loess section. As the isotopic composition varies compli- catedly as shown in the loess-paleosol sequence, it cannot be simply attributed to the abundances of C3 and C4 plants or be used as an indicator of the summer monsoon variations. | CHEN Fahu RAO Zhiguo ZHANG Jiawu JIN Ming MA Jianying | 2006 | Chinese Science Bulletin2006，51，13： | 25 |
| 2 | A 1000-year chironomid-based salinity reconstruction from varved sediments of Sugan Lake,Qaidam Basin,arid Northwest China,and its palaeoclimatic significance显示文摘A 1000-year high-resolution(~10 years) chironomid record from varved sediments of Sugan Lake,Qaidam Basin on the northern Tibetan Plateau,is presented.The chironomid assemblages are mainly composed of the relatively high-saline-water taxa Psectrocladius barbimanus-type and Orthocladius/Cricotopus,and the relatively low-saline-water taxa Procladius and Psectrocladius sordidellus-type.Variations in the chironomid fauna and inferred salinities suggest that over the last millennium,the Sugan Lake catchment has alternated between contrasting climatic conditions,having a dry climate during the period 990―1550 AD,a relatively humid climate during the Little Ice Age(LIA)(1550―1840 AD),and a dry climate again from 1840 AD onwards.At the decadal to centennial scale,a wet event around 1200―1230 AD,interrupting the generally arid period(990―1550 AD),and a dry event around 1590―1700 AD,punctuating the generally humid period(1550―1840 AD),are clearly documented.Trends in the chironomid-based salinity time series indicate a highly unstable climate during the LIA when salinity fluctuations were of greater magnitude and higher frequency.The effective moisture evolution in the Sugan Lake catchment during the last millennium reconstructed by chironomid analysis is in broad agreement with previous palaeo-moisture data derived from other sites in arid Northwest China(ANC).The LIA,characterized by generally humid conditions over the west-erly-dominated ANC was distinctly different from that in monsoonal China,implying an 'out-of-phase' relationship between moisture evolution in these two regions during the past 1000 years. | CHEN JianHui CHEN FaHu ZHANG EnLou BROOKS Stephen J ZHOU AiFeng ZHANG JiaWu | 2009 | Chinese Science Bulletin2009，54，20： | 20 |

| 4 | Climatic changes documented by stable isotopes of sedimentary carbonate in Lake Sugan,northeastern Tibetan Plateau of China,since 2 kaBP显示文摘Lake Sugan at the northern edge of the Qaidam Basin was selected as the research object. The temporal se-quence of sedimentary cores retrieved from Lake Sugan since 2 kaBP was reconstructed using the 210Pb, AMS 14C and conventional 14C dating methods. Carbon and oxygen iso-topes of carbonate in the fine-grained lake sediments were analysed. Combined with the changes of δ 18O values of sur-face water and air temperature observation data in the study area, it might be thought that the δ 18O value of the carbon-ate indicates effective moisture, and the changes in δ 13C val-ues are related to annual freeze-up duration of the lake and indirectly indicate air temperature changes in winter half year. From the above, the sequence of climatic changes in the region since 2 kaBP was established. The climatic changes experienced five stages: Warm-dry climate during 0-190 AD; cold-dry climate during 190-580 AD; warm-dry cli-mate during 580-1200 AD (MWP); cold-wet climate during 1200-1880 AD (LIA); cold-dry climate during 1880-1950 AD; and climate warming since 1950s. The air temperature changes in winter half year reflected by carbon isotope since 2 kaBP are in good agreement with the historical literature records and other geologic records, which shows that the climate changes recorded by the stable isotopes from Lake Sugan since 2 kaBP are of universal significance. | QIANG Mingrui CHEN Fahu ZHANG Jiawu GAO Shang-yu ZHOU Aifeng | 2005 | Chinese Science Bulletin2005，50，17： | 19 |
| 5 | The discovery of annually laminated sediments (varves) from shallow Sugan Lake in inland arid China and their paleoclimatic significance显示文摘Detailed examination of sedimentary cores retrieved from Sugan Lake in the northern Qaidam Basin of northwest China’s Tibetan Plateau reveal that fine laminated beddings form in the sediments where water depth exceeds 3 m. Seasonal surface sediments trapped at the bottom of the lake suggest that sediments deposited during summer and autumn are mainly light colored monohydrocalcites, while those deposited in winter are dark organic matter, indicating that varve layers form under modern limnological conditions. Continuous varve sediments comprising four types have accumulated in the upper 5.5 m of Core SG03I from the center of the lake. All types exhibit clear seasonality indicative of annual deposition. Varve counts correspondence with 210Pb dates on recent sediments in the upper core suggest the continuous varves of the upper 5.5 m of the core formed in the late Holocene (2670 a BP). The Sugan Lake varve sequence is the first demonstration of annually laminated sediments re-ported in arid western China. | ZHOU AiFeng CHEN FaHu QIANG MingRui YANG MeiLin ZHANG JiaWu | 2007 | Science China Earth Sciences2007，50，8： | 17 |
| 6 | Comparison of the carbon isotope composition of total organic carbon and long-chain n-alkanes from surface soils in eastern China and their significance显示文摘Surface soil samples collected over a high spatial resolution in eastern China were analyzed for carbon isotope composition(δ 13C) of total organic carbon(TOC) and higher plant-derived long-chain n-alkanes,with the latter reported as weighted mean values.The two sets of δ 13C values are significantly correlated and show similar trends in spatial variation.The spatial distribution of δ 13C shows less negative values in the mid-latitudes between 31°N and 40°N and more negative ones at higher and lower latitudes.This is consistent with previously reported carbon isotope data from surface soil phytoliths in the same region and suggests that the mid-latitude area provides relatively favorable growing conditions for C4 plants.Furthermore,δ 13C values of both TOC and long-chain n-alkanes from 12 surface soil samples collected from a small grassland in north China displayed similar carbon isotope values and the difference between paired δ 13C of a soil samples remains relatively constant.Our data demonstrate that in eastern China,soil δ 13C composition of both TOC and long-chain n-alkanes is effective indicators of C3/C4 ratios of the prevailing vegetation.This work suggests that -22‰ and -32‰ are good estimated end members for the weighted mean δ 13C values of long-chain n-alkanes(C27,C29 and C31 n-alkanes) from soils under dominant C4 or C3 vegetation,allowing us to reconstruct paleovegetation trends. | RAO ZhiGuo JIA GuoDong ZHU ZhaoYu WU Yi ZHANG JiaWu | 2008 | Chinese Science Bulletin2008，53，24： | 10 |
| 7 | Relationship between climatic conditions and the relative abundance of modern C_3 and C_4 plants in three regions around the North Pacific显示文摘Using -24‰ and -14‰ as the endpoints of stable carbon isotopic composition of total organic carbon (δ 13CTOC) of surface soil under pure C3 and C4 vegetation, and surface soil δ 13CTOC data from eastern China, Australia and the Great Plains of North America, we estimate the relative abundance of C3/C4 plants (i.e., the ratio of C3 or C4 biomass to local primary production) in modern vegetation for each region. The relative abundance of modern C3/C4 vegetation from each region is compared to the corresponding climatic parameters (mean annual temperature and precipitation) to explore the relationship between relative C4 abundance and climate. The results indicate that temperature controls the growth of C4 plants. However, even where temperature is high enough for the growth of C4 plants, they will only dominate the landscape when precipitation declines as temperatures increase. Our results are consistent with those of other investigations of the geographic distribution of modern C4 plant species. Therefore, our results provide an important reference for interpretation of past C3/C4 relative abundance records in these three regions. | RAO ZhiGuo ZHU ZhaoYu JIA GuoDong CHEN FaHu BARTON Loukas ZHANG JiaWu QIANG MingRui | 2010 | Chinese Science Bulletin2010，55，18： | 7 |
| 8 | Effects of climate change and human activity on lake shrinkage in Gonghe Basin of northeastern Tibetan Plateau during the past 60 years显示文摘Changes in the status of freshwater resources are a topic of major global,regional and local concern.This is especially so in the arid and semi-arid regions of China,where shortage of water resources plays a crucial role in limiting sustainable socioeconomic development,as well as in sustaining natural ecosystems.Recent climate change,as well as the effects of localized human activity,such as the use of water for irrigation agriculture,may have significant effects on the status of the water resources in the region.Here,we report the results of a study of changes in the areas of lakes in Gonghe Basin,northeastern Tibetan Plateau of China,over the last 60 years.The data were acquired from optical satellite images and demonstrate that the total water area of lakes in Gonghe Basin decreased significantly from the 1950 s to 1980 s.The cause is ascribed mainly to human activity including exploitation of farmland,against a background of increasing population;in addition,climatic data for the region demonstrate a minor drying trend during this period as the temperature increased slightly.After the construction of several reservoirs,significant amounts of water were redistributed to promote irrigation agriculture and we conclude that this caused a significant shrinkage of the natural lakes.However,both the area of farmland and the population size remained approximately constant after 1990.We conclude that the variation of the total area of lakes during the second period was mainly controlled by climatic factors(precipitation and temperature).As the regional temperature reached a new high,the area of some of the lakes decreased sharply before finally maintaining a relatively steady state.We emphasize that anthropogenic climate change and human activity have both significantly influenced the status of water resources in the arid and semi-arid regions of China. | WU Duo CHEN Fahu LI Kai XIE Yaowen ZHANG Jiawu ZHOU Aifeng | 2016 | Journal of Arid Land2016，8，4： | 6 |
| 9 | Extension of drylands in northern China around 250 kaBP linked with the uplift of the southeast margin of Tibetan Plateau显示文摘Study on two loess sections, one located at Wu-wei near the Tengger Desert in northwestern China, another located near Ganzi at the southeast margin of the Tibetan Plateau in southwest China, reveals a coeval drying step occurred at -250 kaBP. It is expressed by the increase in eolian grain-size at Wuwei, and by a drastic extension of C4 plants and a decrease of loess chemical weathering intensity at Ganzi. Examination of the available eolian data indicates that the event has also been clearly documented in the loess sections near the deserts in northern China, and in the eolian records from the North Pacific. On the contrary, the signal is rather weak for the central and southern Loess Plateau regions as well as for Central Asia, where the climates are influenced by the southeast Asian monsoon and the westerlies, respectively. Since the climate at Ganzi is under strong control of the southwest Asian monsoon, we interpret this drying step as a result of decreased influence of the southwest summer | WU Haibin GUO Zhengtang FANG Xiaomin ZHANG Jiawu CHEN Fahu | 2002 | Chinese Science Bulletin2002，47，20： | 5 |
| 10 | Mapping and breeding value evaluation of a semi-dominant semidwarf gene in upland rice显示文摘Plant height is an important trait related to yield potential and plant architecture.A suitable plant height plays a crucial role in improvement of rice yield and lodging resistance.In this study,we found that the traditional upland landrace 'Kaowenghan'(KWH) showed a special semi-dwarf phenotype.To identify the semi-dwarf gene from KWH,we raised BC2 F4 semi-dwarf introgression lines(IL) by hybridization of the japonica rice cultivar 'Dianjingyou1'(DJY1) and KWH in a DJY1 background.The plant height of the homozygous semi-dwarf IL(IL-87) was significantly reduced compared with that of DJY1.The phenotype of the F1 progeny of the semi-dwarf IL-87 and DJY1 showed that the semi-dwarf phenotype was semidominant.QTL mapping indicated that the semi-dwarf phenotype was controlled by a major QTL q DH1 and was localized between the markers RM6696 and RM12047 on chromosome 1.We also developed near-isogenic lines(NIL) from the BC3 F3 population,and found that the yield of homozygous NIL(NIL-2)was not significantly different compared to DJY1.Breeding value evaluation through investigation of the plant height of the progeny of NIL(NIL-2) and cultivars from different genetic background indicate that the novel semi-dwarf gene shows potential as a genetic resource for rice breeding. | Xiaoqian Chen Peng Xu Jiawu Zhou Dayun Tao Diqiu Yu | 2018 | Plant Diversity2018，40，5： | 3 |

| 12 | Different climatic controls of soil δ^(13)C_(org) in three mid-latitude regions of the Northern Hemisphere since the Last Glacial period显示文摘Paleoecological records of soil δ13Corg from three regions in the middle latitudes of the Northern Hemisphere, including the Chinese Loess Plateau (CLP), the Great Plains and adjacent areas of North America and northwestern Europe, showed different variations since the Last Glacial period. An at-tempt was made to evaluate the causes for the difference in δ13Corg on the basis of the modern climatic data collected in these regions and of the modern C3 and C4 plant distributions. The analysis indicates that temperature, especially the growing season temperature, has a dominant control on the growth of C4 plants. When the mean annual or growing season temperatures are below the 'threshold value' , the growth of C4 plants is limited. When the temperature is above the 'threshold value' , C4 plants can grow under a wide range of precipitation. However, when the precipitation is high enough to favor the growth of trees, the proportions of C4 plants in local biomass will decline. The implicit control factor recovered by sedimentary records is consistent with the control factor on modern C3/C4 distribution. Pure C3 plants have been dominating the local biomass since the Last Glacial period in European loess region, mainly owing to the low local temperature. The increases in C4 plants from the late Pleistocene to the Holocene in the Chinese Loess Plateau, the Great Plains and adjacent areas, mainly reflect the influ-ence of increasing temperature. | RAO ZhiGuo ZHU ZhaoYu ZHANG JiaWu | 2007 | Chinese Science Bulletin2007，52，2： | 2 |

| 16 | Natural alleles of a uridine 5'-diphospho-glucosyltransferase gene responsible for differential endosperm development between upland rice and paddy rice显示文摘Traditional upland rice generally exhibits insufficient grains resulting from abnormal endosperm development compared to paddy rice. However, the underlying molecular mechanism of this trait is poorly understood. Here,we cloned the uridine 5’-diphospho(UDP)-glucosyltransferase gene EDR1(Endosperm Development in Rice) responsible for differential endosperm development between upland rice and paddy rice by performing quantitative trait loci analysis and map-based cloning. EDR1 was highly expressed in developing seeds duringgrain filling. Natural variations in EDR1 significantly reduced the UDP-glucosyltransferase activity of EDR1 YZNcompared to EDR1 YD1,resulting in abnormal endosperm development in the near-isogenic line, accompanied by insufficient grains and changes in grain quality.By analyzing the distribution of the two alleles EDR1 YD1 and EDR1 YZNamong diverse paddy rice and upland rice varieties, we discovered that EDR1 was conserved in upland rice, but segregated in paddy rice. Further analyses of grain chalkiness in the alleles of EDR1 YD1 and EDR1 YZNvarieties indicated that rice varieties harboring EDR1 YZNand EDR1 YD1 preferentially showed high chalkiness, and low chalkiness,respectively. Taken together, these results suggest that the UDP-glucosyltransferase gene EDR1 is an important determinant controlling differential endosperm development between upland rice and paddy rice. | Zihao Wu Xiao Zhang Guimei Chang Jun Yang Jinpeng Wan Feijun Wang Dayun Tao Jiawu Zhou Lianguang Shang Peng Xu Diqiu Yu | 2022 | Journal of Integrative Plant Biology2022，64，1： | 1 |
