摘  要:
在全面定位调查并建立崩岗GIS数据库的基础上,运用GIS空间分析技术,对中国南方崩岗的空间分布特点进行研究。通过岩性、土壤、地形、降雨、气温等自然因子对崩岗分布数量的影响分析,确定中国南方崩岗主要分布在年均降雨量为1 300~2 000mm、年均气温为15~22℃、海拔500m以下的花岗岩红壤丘陵区。

摘  要:
Effects of natural factors including lithology,soil,landform,rainfall and temperature on the hill collapse distribution were analysed based on the overall location survey and the establishment of GIS database.Characteristics of the hill collapse dispersion were first studied by means of GIS space analytic technology.It was found that the hill collapse principally occurs in the granite-red soil hill characterized by an average annual rainfall of 1 300-2 000 mm,an average annual temperature of 15-22 ℃ and a sea level below 500 m.The current research maybe instructive for the planning of the hill collapse and its prevention and control.
