基于GIS的酸雨灾害损失评价

Model of Acid Rain Damage Loss Based on GIS

酸雨灾害损失评估是酸雨灾害风险评价的重要研究内容,但是目前关于酸雨灾害损失评价指标体系与模型还不够完善,为此提出了酸雨灾害损失评价的方法.方法从自然和社会易损性两个角度出发,选取地理高程,人口密度和土地利用数据为指标,采用加权的叠加分析进行区域酸雨灾害损失评价,得出酸雨灾害损失评价图,并通过实例详细分析了酸雨灾害损失评价方法的应用.

Model of acid rain damage loss is the important research content of risk evaluation of acid rain hazard ,and at present the index system and model of loss assessment of the damage of acid rain hazards are imperfect. The article with aspect of natrue and society,make use of evelation,the dense of population and use of land,weighted overlay method was adopted and model of acid rain damage loss was established, finally, the chart of acid rain damage loss is attained. What is more,the application of the model was futher expounded with example.
