摘要
以干旱半干旱地区——新疆哈密市双井子有色金属26号铁矿为研究区,通过对崩塌、滑坡、泥石流、地面塌陷、沉降、地裂缝6大灾种因子进行定性和定量相结合的危险度分析,充分利用GIS的计算与空间分析功能,将研究区各潜在灾种因子叠加分析,最终编制出研究区的地质灾害危险性评估分区图。该图描述了在现有自然条件和人类工程活动下的潜在地质灾害危险区。研究成果可为全面反映灾情,确定减灾目标,优化防御措施,进行科学地减灾决策提供重要依据。
This paper conducted qualitative and quantitative risk analysis on six major disasters including collapse, landslides, debris flows, ground subsidence, cracks and settlement by taking on the arid and semi-arid areas - the 26th Shuangjingzi metal iron in Hami City, Xinjiang Uygur Autonomous Region as the study areas, and finally made a district map for geological hazard assessment about the study area by making full use of the calculation and spatial analysis function of GIS and studying the potential disaster zone of stacking factor analysis. The map described the potential dangerous area under the existing natural conditions and human engineering activities. Study results offered a valuable basis for reflecting the overall disaster, identifying disaster reduction objectives, optimizing defensive measures and making scientific and mitigation decisions.
