基于GIS和AHP的安庆市2006—2016年城市生态环境动态评价研究
|
摘要
近年来,城市化进程不断加快,城市生态环境变化受到广泛关注。城市生态环境研究手段由简单定性分析向注重定量分析发展。本文以安庆市为研究对象,利用层次分析法(AHP)中的主观赋值法和德尔非法确定指标权重,通过GIS技术对各指标数据进行空间叠加分析并进行可视化表达,对安庆市2006年与2016年相同的13个生态环境评价指标,对比分析安庆市城市生态环境动态变化。结合安庆市发展实际,分析变化的形成原因及存在问题,提出具体建议。
In recent years, the process of urbanization is accelerating, and the changes in urban ecological environment have received extensive attention. The research method of urban ecological environment is developed from simple qualitative analysis to more quantitative analysis. This paper takes Anqing City as the research object, and uses 13 eco-environmental evaluation indicators of Anqing city in 2006 and 2016 to make comparative analysis. In this paper, the hierarchical model are used to establish the index, which mainly adopts the subjective valuation method and the weight of the index. Using geographic information system(GIS), the data can be visualized and compared to analyze urban ecological changes. Based on the actual development of Anqing City, the reasons for the formation of the changes and existing problems are analyzed, and specific suggestions are put forward.
