摘要: 结合辽宁省新宾县地质灾害发育情况,在充分分析影响该地区地质灾害发生发展的自然因素和人为因素基础上,应用模糊综合评判方法,通过网格单元剖分,对泥石流、崩塌、滑坡、地面塌陷、地裂缝5种地质灾害进行易发程度划分与评价.结合Visual BASIC软件编程对各单元区评定等级,对其数字化结果进行叠加分析,最后应用Sufer 7.0软件生成等值线进行了新宾县地质灾害易发区的划分并作出评价.Abstract: With the study on the development of geologic hazards in Xinbin County, Liaoning Province, the natural and artificial factors that affect the happening and developing of geologic hazards in the area are analyzed. Applying fuzzy comprehensive evaluation method, the easy-happening degree of five types of geologic hazards, such as mudflow, collapse, landslide, ground breakdown and ground crack, are divided and assessed by grid splitting. The digitalized results are superimposed and analyzed with the software Visual BASIC, and then assessed and graded for each unit. Finally the easyhappening areas of geologic hazards in Xinbin are divided and assessed with Sufer 7.0.
