| 1 | Susceptibility Assessment of Landslides Caused by the Wenchuan Earthquake Using a Logistic Regression Model显示文摘The Wenchuan earthquake on May 12,2008 caused numerous collapses,landslides,barrier lakes,and debris flows.Landslide susceptibility mapping is important for evaluation of environmental capacity and also as a guide for post-earthquake reconstruction.In this paper,a logistic regression model was developed within the framework of GIS to map landslide susceptibility.Qingchuan County,a heavily affected area,was selected for the study.Distribution of landslides was prepared by interpretation of multi-temporal and multi-resolution remote sensing images(ADS40 aerial imagery,SPOT5 imagery and TM imagery,etc.) and field surveys.The Certainly Factor method was used to find the influencial factors,indicating that lithologic groups,distance from major faults,slope angle,profile curvature,and altitude are the dominant factors influencing landslides.The weight of each factor was determined using a binomial logistic regression model.Landslide susceptibility mapping was based on spatial overlay analysis and divided into five classes.Major faults have the most significant impact,and landslides will occur most likely in areas near the faults.Onethird of the area has a high or very high susceptibility,located in the northeast,south and southwest,including 65.3% of all landslides coincident with the earthquake.The susceptibility map can reveal the likelihood of future failures,and it will be useful for planners during the rebuilding process and for future zoning issues. | SU Fenghuan | 2010 | Journal of Mountain Science2010，7，3： | 14 |
| 2 | GIS-Based Risk Assessment of Debris Flow Disasters in the Upper Reach of Yangtze River显示文摘This paper discussed theory and methodologies of debris-flow risk assessment and established an implementation process according to indicators of debris-flow hazard degree,vulnerability,risk degree,etc. Among these methodologies,historical and potential hazard degree was comprehensively considered into hazard assessment and hazard index was presented to indicate the debris-flow hazard degree. Regarding debris-flow vulnerability assessment,its statistical data and calculating procedure were based on the hazard-degree regionalization instead of administrative divisions,which improved the as-sessing scientificity and precision. These quantitative methodologies inte-grated with Geography Information System(GIS) were applied to the risk assessment of debris flows in the upper reach of Yangtze River. Its results were in substantial agreement on investigation data and the actual distribution of debris flows,which showed that these principles and methodologies were reasonable and feasible and can provide basis or reference for debris-flow risk assessment and disaster management. | HAN Yongshun LIU Hongjiang ZHONG Dunlun SU Fenghuan LI Chaokui | 2007 | Wuhan University Journal of Natural Sciences2007，12，4： | 9 |

| 7 | 2004~2008年704例大肠癌临床流行特征(英文)显示文摘Objective:The aim of the research was to study the clinical and epidemiological characteristics of incidence of colorectal cancer in North China. Methods: Analysis and summary were made for 704 colorectal cancer patients diagnosed from 2004 to 2008 in North China. Results: (1) Of 704 colorectal cancer patients,the median age was 56 years old,and the mean age was 58.2. There was no statistic difference in age between male and female cases,P > 0.05. (2) The male-female ratio was 1.62:1. (3) The proportion of rectal cancer was 62.92%,and incidence of the left colon cancer was higher than that of right colon cancer,P<0.05.(4) Of 712 lesions,658 cases were adenocarcinoma accounting for 92.4%,34 were malignant adenoma accounting for 4.8%,and 20 carcinoid accounting for 2.8%. (5) The 48.9% of patients belonged to stages 0 to IIB. Conclusion:The cases of colorectal cancer in North China is mainly rectal cancers,and the incidence of left colon cancer is higher than that of right colon cancer. The histopathological classification is mainly adenocarcinoma,and the ratio of early stage is high. | Shaoqing Lai Fenghuan Ju Guiqi Wang Shun He Xiaoguang Ni Lei Zhang Guixiang Yu Yueming Zhang Xiaoyan Li | 2010 | The Chinese-German Journal of Clinical Oncology2010，9，6： | 1 |
