摘要/Abstract

摘要： 楚雄市是一个地质灾害多发,以滑坡、泥石流为主的城市,地质灾害对于当地人民的人身和财产造成了巨大损失。本文基于DEM数据,运用ArcGIS技术,分析坡度、坡向与地质灾害易发区划的关系,对研究区地质灾害易发区进行划定。通过研究调查发现,地质灾害高易发区占总面积的15.4%,分布在树苴乡、三街镇、八角镇、西舍路乡、中山镇全部及新村镇和大过口乡的部分区域;地质灾害中易发区占总面积的36.4%,主要分布在大过口乡、新村镇、大地基乡、东华镇、子午镇的云龙、挖铜村委会,鹿城镇的新村、山咀子村委会和苍岭镇的部分地区;地质灾害低易发区占总面积的47.1%,分布在吕合镇、紫溪镇、东瓜镇、鹿城镇的大部及苍岭镇的部分地区;地质灾害非易发区只占总面积的1.1%,分布在坝区的楚雄盆地、苍岭盆地和子午盆地。

Abstract: Chuxiong is a city of frequent geological disasters-landslides and debri flows in particular-that cause great personal and property losses to the locals.Based on DEM data,this paper analyzes the relationship between slope,slope direction and geological delimit of frequent disasters with the ArcGIS technology so as to delimit the studied area prone to geological disasters.The results show1) regions of highly-frequent geological disasters-mainly distributed in Shuzuo Township,Sanjie Township,Bajiao Township,Xishelu Township and Zhongshan Township as well as most parts of Xinjie and Daguokou townships-account for 15.4% of the total area;2) regions of intermediately-frequent geological disasters-mainly distributed in Daguokou Township,Xinjie Township,Dadiji Township,Donghua Township and most parts of Ziwu Township-accounted for 36.4% of total area;3) regions of lowly-frequent geological disasters-mainly distributed in Luhe Township,Zixi Township,Donggua Township and many parts of Lucheng Township-accounted for 47.1% of the total area;and 4) regions free of geological disasterss-mainly distributed in the Chuxiong Basin,Cangling Basin and Zixu Baison-only accounted for 1.1% of the total area.

Key words: Chuxiong City, DEM, aspect, slope, geological disaster
