| 1 | Toward a general evaluation model for soil respiration (GEMSR)显示文摘Soil respiration is an important component of terrestrial carbon budget. Its accurate evaluation is es- sential to the study of terrestrial carbon source/sink. Studies on soil respiration at present mostly focus on the temporal variations and the controlling factors of soil respiration, but its spatial variations and controlling factors draw less attention. Moreover, the evaluation models for soil respiration at present include only the effects of water and heat factors, while the biological and soil factors controlling soil respiration and their interactions with water and heat factors have not been considered yet. These models are not able to accurately evaluate soil respiration in different vegetation/terrestrial ecosystems at different temporal and spatial scales. Thus, a general evaluation model for soil respiration (GEMSR) including the interacting meteorological (water and heat factors), soil nutrient and biological factors is suggested in this paper, and the basic procedure developing GEMSR and the research tasks of soil respiration in the future are also discussed. | ZHOU GuangSheng, JIA BingRui, HAN GuangXuan & ZHOU Li Key Laboratory of Vegetation and Environmental Change, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China | 2008 | Science China(Life Sciences)2008，51，3： | 12 |
| 2 | Nitrogen Deposition and Its Spatial Pattern in Main Forest Ecosystems along North-South Transect of Eastern China显示文摘A continuous three-year observation(from May 2008 to April 2011)was conducted to characterize the spatial variation of dissolved inorganic nitrogen(DIN)deposition at eight main forest ecosystems along the north-south transect of eastern China(NSTEC).The results show that both throughfall DIN deposition and bulk DIN deposition increase from north to south along the NSTEC.Throughfall DIN deposition varies greatly from 2.7 kg N/(ha·yr)to 33.0 kg N/(ha·yr),with an average of 10.6 kg N/(ha·yr),and bulk DIN deposition ranges from 4.1 kg N/(ha·yr)to 25.4 kg N/(ha·yr),with an average of 9.8 kg N/(ha·yr).NH4+-N is the dominant form of DIN deposition at most sampling sites.Additionally,the spatial variation of DIN deposition is controlled mainly by precipitation.Moreover,in the northern part of the NSTEC,bulk DIN deposition is 17%higher than throughfall DIN deposition,whereas the trend is opposite in the southern part of the NSTEC.The results demonstrate that DIN deposition would likely threaten the forest ecosystems along the NSTEC,compared with the critical loads(CL)of N deposition,and DIN deposition in this region is mostly controlled by agricultural activities rather than industrial activities or transportation. | ZHAN Xiaoyun YU Guirui HE Nianpeng FANG Huajun JIA Bingrui ZHOU Mei WANG Chuankuan ZHANG Junhui ZHAO Guangdong WANG Silong LIU Yunfen YAN Junhua | 2014 | Chinese Geographical Science2014，24，2： | 10 |

| 9 | Quantifying the interannual litterfall variations in China’s forest ecosystems显示文摘凋落物是森林生物地化学循环和火险预测的关键参数。然而,森林凋落物如何随林龄变化仍不清楚。因此,量化森林生态系统凋落物年际变化对减少大尺度凋落物预测的不确定性至关重要。本论文基于中国人工林和次生林凋落物连续多年(≥2年)测定的数据集(N=318),采用变异系数(CV)、变化百分比(V_(P))和年际间比率量化凋落物的年际变化。研究结果表明,凋落物的年际变化随林龄增加(1–90年生)而呈下降趋势。其中,1–10年林龄的凋落物年际变化最大(平均CV=23.51%,平均V_(P)=-28.59%~20.89%),其主要原因在于树木早期快速生长,即下一年与当年凋落物比率平均为1.20。11–40年林龄的凋落物年际变化逐渐减小,但CV平均值仍在18%左右,V_(P)平均值在-17.69%~21.19%之间。41–90年林龄的凋落物年际变化最小,CV平均值仅为8.98%,V_(P)平均值维持在8%左右。因此,大于40年林龄的凋落物量较低且稳定。这一结果与已有研究的认知不同:即当林龄大于30年、20年甚至15年时,森林凋落物量达到相对稳定。本研究结果将有助于我们深入理解森林凋落物生态学,并为大尺度碳收支和生物地化学循环模型提供基础。 | Bingrui Jia Hongru Sun Wenying Yu Guangsheng Zhou | 2020 | Journal of Plant Ecology2020，13，3： | 0 |
| 10 | Evaluation of N Fertilizers Effects on Grape Based on the Expression of N Metabolic Genes显示文摘In order to study the influence of different types of N fertilizers on grapevine(Vitis labruscana ‘Black Summer') trees were used as experiment materials and fertilizers foliar application trails were conducted in the flowering and veraison stages. The expression levels of five grapevine N metabolic genes, including Vv GHD, Vv Ni R, Vv NR, Vv GS and Vv AS, were analyzed, some physiological traits including the flower and fruit dropping rate, leaves and shoots growth rate, chlorophyll content and the fruit size of grape berry were also investigated. The results showed that,in general, the expression levels of the five N metabolic genes were increased after foliar applied different types of N fertilizers in the two periods.N metabolic genes showed similar expression patterns toward the same type of fertilizer in the two periods, whereas foliar applied different types of N fertilizers, their expression patterns changed. Moreover, the N fertilizer which had stronger and longer influence on the N metabolic genes could enhance the physiology traits more dramatically. Given the gene expression levels and the changes of physiology traits, we conclude that urea and ammonium nitrate have the best effect on grapevine; calcium nitrate can help to reduce the flower and berry dropping rate; ammonium sulphate and sodium nitrate have relatively poor effects on grapevine. | WANG Jian LI Bingrui LI Xiaopeng ZHU Xudong ZHU Chuangen JIA Haifeng | 2016 | Horticultural Plant Journal2016，2，5： | 0 |
