摘要:粤西地区属低山丘陵山地地貌,由于历史等原因,农村削坡建房现象非常普遍。而削坡建房又是引发地质灾害现象发生的主要原因之一,因此,如何管理、解決削坡建房问题从而避免引发地质灾害,成为亟须探究解决的问题。作者以广东省郁南县为例,总结了削坡建房的现状,分析了存在的困境,并提出了相应对策,对今后我省削坡建房问题的解决具有借鉴意义。

Abstract: There are many low mountains and hills in west of Guangdong province. Due to historical reasons,the phenomenon of building houses by cutting slopes is general. And it is one of the main causes of geological disasters. Therefore,how to solve the problem become an urgent problem. Taking Yunan County of Guangdong Province as an example,the author summarizes the current situation of building houses by cutting slopes,analyzes the existing difficulties,and puts forward corresponding countermeasures,which has reference significance for solving the problems of building houses by cutting slopes in our province in the future.

1.概述
粤西地区属低山丘陵山地地貌,人口多耕地少,又由于历史等原因,农村建设总体规划和村庄建设规划滞后,导致农村削坡建房现象非常普遍。同时,粤西地区为广东三大暴雨中心之一,暴雨、台风等强对流天气频发[1],在恶劣气象条件下,往往加速山体或斜坡诱发滑坡、崩塌、泥石流等地质灾害,给人民生命财产带来重大破坏[2]。据统计,削坡建房未采取任何防护措施,发生滑坡、崩塌地质灾害的占全省的90.3%[3]。由此可见,在粤西地区乃至广东全省范围内,削坡建房都是引发地质灾害现象发生的主要原因之一。因此,如何避免因削坡建房而引发地质灾害成为亟须探究解决的问题。笔者以广东省郁南县为例,对削坡建房做了较为细致的研究,并且对如何避免做了一些探究。
郁南县位于广东省西部,属于较为典型的低山丘陵地貌。县境内的气候为亚热带季风气候。3月-9月为雨季,雨量充沛,台风季节经常局地暴雨,易于诱发地质灾害。……
