中文摘要: 汶川5.12大地震发生后,成都市的都江堰等西部5个市县遭受了不同程度的破坏。灾区的资源环境承载力快速评价将为灾后重建规划提供直接参考。由于以往资源承载力评价多为特定区域单指标评价,本文根据资源承载力评价的定义确定了适用目标与对象,并根据实际情况采用采用多因素综合评定目标区域承载力。评价指标包括地质灾害、地貌环境、耕地、水、旅游资源五项,各因素权重由专家系统确定。通过GIS工具对研究区域按3×3km进行栅格化处理,叠加各因素图层,得出各单元的资源环境承载力的初步结果。该结果与实际情况对照相符。最后根据评价结果提出了相应的建议。
Abstract:Wenchuan earthquake caused great damage to Dujiangyan and other 4 counties of Chengdu. The quick evaluation on environment resources carrying capacity is an important part of the post-earthquake reconstruction plan. Current carrying capacity usually evaluate single resources of a certain area, few of them assess a whole city. This paper get the evaluated target and objects according to the carrying capacity definitions. Five factors including geology disasters’ distribution, physiognomy environment, plow land, water and travel resource were used for evaluation the carrying capacity of a city area. Each factor’s weight got from the specialists. The research area were divided to 3×3km grids by GIS software. The final result is make up with grid’s evaluation result which concluded by five factor layer’s overlay. Some suggestions base on the evaluation result were given and the end.
