| 1 | Changes in sediment discharge in a sediment-rich region of the Yellow River from 1955 to 2010: implications for further soil erosion control显示文摘The well-documented decrease in the discharge of sediment into the Yellow River has attracted considerable attention in recent years. The present study analyzed the spatial and temporal variation of sediment yield based on data from 46 hydrological stations in the sediment-rich region of the Yellow River from 1955 to 2010. The results showed that since 1970 sediment yield in the region has clearly decreased at different rates in the 45 sub-areas controlled by hydrological stations. The decrease in sediment yield was closely related to the intensity and extent of soil erosion control measures and rainstorms that occurred in different periods and sub-areas. The average sediment delivery modulus(SDM) in the study area decreased from 7,767.4 t/(km2?a) in 1951–1969 to 980.5 t/(km2?a) in 2000–2010. Our study suggested that 65.5% of the study area with the SDM below 1,000 t/(km2?a) is still necessary to control soil deterioration caused by erosion, and soil erosion control measures should be further strengthened in the areas with the SDM above 1,000 t/(km2?a). | JuYing JIAO ZhiJie WANG GuangJu ZHAO WanZhong WANG XingMin MU | 2014 | Journal of Arid Land2014，6，5： | 7 |
| 2 | Soil erosion and sediment interception by check dams in a watershed for an extreme rainstorm on the Loess Plateau,China显示文摘The magnitude of soil erosion and sediment load reduction efficiency of check dams under extreme rainstorms is a long-standing concern.The current paper aims to use check dams to deduce the amount of soil erosion under extreme rainstorms in a watershed and to identify the difference in sediment interception efficiency of different types of check dams.Based on the sediment deposition at 12 check dams with 100% sediment interception efficiency and sub-catchment clustering by taking 12 damcontrolled catchments as clustering criteria,the amount of soil erosion resulting from an extreme rainstorm event on July 26,2017(named '7·26' extreme rainstorm) was estimated in the Chabagou watershed in the hill and gully region of the Loess Plateau.The differences in the sediment interception efficiency among the check dams in the watershed were analyzed according to field observations at 17 check dams.The results show that the average erosion intensity under the '7-26' extreme rainstorm was approximately 2.03×10~4 t/km^2,which was 5 times that in the second largest erosive rainfall in 2017(4.15×10~3 t/km^2) and 11-384 times that for storms in 2018(0.53×10~2 t/km^2-1.81×10~3 t/km^2).Under the '7-26' extreme rainstorm,the amount of soil erosion in the Chabagou watershed above the Caoping hydrological station was 4.20 × 106 t.The sediment interception efficiency of the check dams with drainage canals(including the destroyed check dams) and with drainage culverts was 6.48 and 39.49%,respectively.The total actual sediment amount trapped by the check dams was 1.11 × 106 t,accounting for 26.36% of the total amount of soil erosion.In contrast,3.09×106 t of sediment were input to the downstream channel,and the sediment deposition in the channel was 2.23×10~6 t,accounting for 53.15%of the total amount of soil erosion.The amount of sediment transport at the hydrological station was8.60×10~5 t.The Sediment Delivery Ratio(SDR) under the '7·26' extreme rainstorm was 0.21.The results indicated that the amount of soil erosion was huge,and the sediment interception efficiency of the check dams was greatly reduced under extreme rainstorms.It is necessary to strengthen the management and construction technology standards of check dams to improve the sediment interception efficiency and flood safety in the watershed. | Leichao Bai Nan Wang Juying Jiao Yixian Chen Bingzhe Tang Haolin Wang Yulan Chen Xiqin Yan Zhijie Wang | 2020 | International Journal of Sediment Research2020，35，4： | 7 |

| 4 | Responses of flood peaks to land use and landscape patterns under extreme rainstorms in small catchments-A case study of the rainstorm of Typhoon Lekima in Shandong,China显示文摘Investigations of the formation mechanisms of flood peaks in small catchments facilitate flood prediction and disaster prevention under extreme rainstorms.However,there have been few studies on the re-sponses of flood peaks to land use landscape patterns using field surveys during extreme rainstorm events.Based on field data from 17 small catchments near the rainstorm center of Typhoon Lekima,7 landscape indices were chosen.The flood peak and its sensitivity to the land use landscape were investigated by combining remote sensing interpretation and related analysis.The conclusions are as follows:(1)The peak discharge of the small catchment was 2.36e56.50 m3/s,the peak modulus was 8.00 e48.89 m3/(s$km2),and the flood index K ranged from 3.61 to 4.55.(2)Under similar rainfall conditions,the flood peak modulus,K and the proportion of sloping cropland had significantly positive correlations(p<0.05).The flood peak modulus was significantly negatively correlated with the proportion of forest-grassland and terrace(p<0.05),and K and the proportion of forest-grassland and terraced land exhibited a negative correlation.(3)The flood peak modulus and K were positively correlated with the landscape fragmentation.(4)The sensitivities of small catchments to floods were evaluated to be moderate compared to K values from other studies.The ability of small catchments to cope with extreme rain-storms can be improved by increasing the areas of forest-grassland,and terraces and reducing landscape fragmentation.Our results could be applied to provide a basis for land use planning and support for the response against disasters caused by extreme floods. | Yuanhao Liu Jianqiao Han Juying Jiao Baoyuan Liu Wenyan Ge Qingbin Pan Fei Wang | 2022 | International Soil and Water Conservation Research2022，10，2： | 1 |

| 7 | Effect of Endostar combined with concurrent chemoradiotherapy in patients with locally advanced cervical cancer显示文摘ObjectiveTo explore the value of Endostar in the clinical application of locally advanced cervical cancer.MethodsA total of 107 patients with locally advanced cervical cancer who received concurrent chemoradiotherapy(CCRT)in the Department of Radiotherapy,the First Affiliated Hospital of Soochow University and Changzhou No.2 People's Hospital between January 2018 and December 2020 were enrolled in this retrospective study.There were 30 cases in the Endostar combined with CCRT(E-CCRT)group and 77 in the CCRT group.Propensity score matching(PSM)was used to reduce confounding factors.The short-term efficacy and long-term survival rate were compared between the E-CCRT group and the CCRT group.ResultsAfter matching,the objective response rates in the E-CCRT group and CCRT group were 86.7%and 63.3%,respectively,with statistically significant difference(χ^(2)=4.356,P=0.037).But there were no statistically significant differences in the disease control rates(96.7%vs.86.7%,χ^(2)=0.873,P=0.350),3-year overall survival(OS)rates(86.7%vs.83.3%,P=0.681),and 3-year disease-free survival(DFS)rates(both 76.7%and 76.7%,P=0.869).There was no statistically significant difference in the incidence of adverse reactions between the two groups.ConclusionsE-CCRT can improve the response of locally advanced cervical cancer patients without increasing the occurrence of adverse reactions,and has the potential to become a new treatment regimen for cervical cancer. | Hengzhao Zhuang Yang Jiao Xin Li Jingping Yu Juying Zhou Lili Wang | 2023 | Radiation Medicine and Protection2023，4，2： | 0 |
