【摘要】 采用了 GPS辅助下的野外调查、野外实地填图进行数据采集和室内 GIS(Arc Info7.0 )辅助下的数据储存、分析方法 ,以西庄河山地流域过去发生的滑坡事件为研究对象 ,初步分析了该山地流域内滑坡事件的时空分布特征及近期滑坡发生的可能趋势。最后 ,提出防治滑坡灾害事件发生的合理化建议 ,为类似流域环境条件下的滑坡灾害的预防与控制提供了参考性意见。更多还原

【Abstract】 In order to obtain the good understanding of the basic condition of serious erosion events, landslide events, in Xizhuang watershed (small scale, middle mountainous watershed), field survey with the assistant of GPS (the global position system) and topography map in 1∶10 000 scales was implemented during dry season 2001～2002 year rounds. Finally, the authors give some recommendations for landslides prevention: a) stopping the quarries’ work and starting to protect the destroyed area; b) suitable measures should be carried out to protect the river bank for the safety of transportation; c) agroforestry measures for farmland protection; d) forestation activities and converting slope farmland into forest land or grassland for environment health and rehabilitation; e) more research input on landslide in the micro scale of mountain watershed.更多还原
