摘要
新源县是新疆滑坡灾害的多发区。基于GIS的多元信息整合与空间分析功能,分析了近年新源县449个滑坡灾害点的监测数据,探讨了该区滑坡的发育特征,进行了滑坡灾害危险性区划。结果表明,地质条件是滑坡灾害形成的基本因素,降雨是滑坡灾害的主要诱发因素,过度放牧等人类活动也是促发滑坡灾害发生发展的重要因素之一。由此,为避免滑坡灾害,减少在上述地形地质条件下的不合理人类活动、合理安排牲畜数量以减少环境负荷是决策关键。
Kunes County is a frequent landslide disasters-happening area in Xinjiang Autonomous Region. Based on muhivariable information integration and spatial analysis function of GIS, recent monitoring data about 449 landslide disaster sites in Kunes County was analyzed, development characteristics of the landslide in this area was explored and hazard zoning of landslide disaster was carried out. Results show that gelogical condition is basic factor of form- ing landslide disasters, rainfall is primary inducting condition of landslide disaster and excessive human being activi- ties is also one of important factors to promote occurrance and development of landslide disasters. We should reduce unreasonable human being activities under above topographic and geological condition and reasonably plan livestock number to reduce environmental load.
