摘要
滇中地区是云南省地质灾害的多发区之一。区内主要地质灾害类型有滑坡、泥石流、崩塌、地面塌陷及地裂缝五种。其中以滑坡和泥石流为主,灾害点分布较广且个体规模小,稳定性较差。此次通过对区内地质灾害诱因及分布现状的分析,阐述了地质灾害防治分区划分原则,将滇中地区划分为地质灾害重点防治区、次重点防治区及一般防治区三个大区,并提出了相应的防治措施。
The district of central area in Yunnan Province, is located in geological hazards easily occurring areas. There are six geological hazards, including landslide, debris flows, collapse, unstable slopes, land collapse and land fractures. Among them, landslide and debris flows are severely harmful and distributed widely, with the characteristic of small scale, frequent activity and low stability. The paper anlayses that the inducement and the present distribution of geological disasters in central area of Yunnan Province, expounds the principles of the zoning of the geological disasters, divides three zones including emphasis prevention area, secondary emphasis prevention area and general prevention area, and advances some corresponding preventing measures.
