摘要

研究目的：我国滑坡灾害分布不均，不同的省份滑坡发育程度因受地质及人文环境的影响而存在较大差别。为了有效地掌握我国各省份滑坡的发育程度，本文利用数据库中所收集的国内 31 个省份的 737 处滑坡体积在［0．5 万方，2500 万方］的滑坡样本，对全国不同省份的滑坡贡献率进行研究。

研究结论：川、渝、鄂、甘、陕、晋、黔、湘、藏、云10 省对我国滑坡的贡献率较大，占总滑坡样本中滑坡贡献率的60．1%，为滑坡危害性较大的区域; 辽、新、赣、苏、宁、黑、吉、鲁、琼、津、沪 11 个省市的滑坡贡献率较低，占总滑坡样本中滑坡贡献率的13．4%，为滑坡的相对不发育区。通过对我国各省份的滑坡贡献率研究，将我国各省份的滑坡发育程度进行了有效的分类，能很好地为我国建设规划及滑坡的预防方面提供有效的参考，为滑坡的防灾减灾工作提供借鉴。

Abstract

Research purposes:The landslide is unevenly distributed in China，and there is big difference in the landslide intensity among the provinces due to the different geological environments and human environment．In order to master development degree of landslide disaster in China，the study was done on the contribution rate of landslide intensity of the different provinces through 737 landslide samples with their landslide volumes between 5×10 and 2.5×107 m3collected from 31 provinces in China．

Research conclusions: The contribution rates of landslide intensity of 10 provinces，including Sichuan，Chongqing，Hubei，Gansu，Shaanxi，shanxi，Guizhou，Hunan，Xizang，and Yunnan are high with distribution rate up to 60.1% of the total distribution rate，and they belong to the high intensity regions of landslides． The distribution rate of landslide of the another 11 provinces，including Liaoning，Xinjiang，Jiangxi，Jiangsu，Ningxia Heilongjiang，Tianjin，Jilin，Shandong，Hainan，and Shanghai are low with rate up to 13.4% of of total rate and they belong to the low intensityregions of landslides． After the study on the contribution rate of landslide intensity of each province in China，this paper presents an efficient classification of landslide intensity for providing the references to the construction programs and the landslide prevention．
