摘要
怒江州地处滇西高原,怒江流域中上部,地质灾害多发,尤以滑坡灾害为甚,严重威胁当地人民生命财产和社会经济活动。怒江州滑坡灾害易发性区划的深入研究对怒江流域乃至整个滇西的自然灾害防灾减灾工作具有重要指导意义。本文根据云南省地质调查局提供的滑坡隐患点分布数据,广泛收集地形地貌、气象降雨、植被覆盖、水系分布等数据,利用主成分分析方法选取灾害影响因子,构建二元Logistic回归模型,最终划分怒江州滑坡灾害的易发性分区。本文准确地反映了怒江州滑坡灾害易发区分布,对指导滑坡灾害防治有重要意义。
Nujiang prefecture is located in the west Yunnan Plateau and the middle and upper part of the Nujiang valley. It is of great significance for the prevention and reduction of natural disasters in the Nujiang valley basin and the whole west of Yunnan to study the vulnerability zoning of landslides in Nujiang prefecture. Based on the distribution data of landslide hidden danger points provided by Yunnan Geological Survey Bureau, this paper extensively collects the data of topography, weather and rainfall, vegetation cover, distribution of water system, etc.,the binary Logistic regression model is constructed to divide the landslide prone area of Nujiang prefecture, which reflects exactly the distribution of the landslide prone area of Nujiang prefecture.
