基于GIS与AHP的阜阳市生态环境评价研究

Evaluation of urban ecological environment in Fuyang based on GIS and AHP

城市化和工业化的迅速发展,给社会带来巨大效益的同时也带来了诸多问题,城市生态环境的恶化成为人们普遍关心的问题之一。本文以阜阳市为例,从城市面临的诸多环境问题出发,构建评价指标体系,选取21个指标对阜阳市的生态环境现状进行评价分析;再通过层次分析法来确定权重,应用GIS空间叠加分析确定阜阳市生态环境评价等级空间分布图。结果发现优质区和良好区分布在太和县、临泉县以及颍州区的大部分区,占49.69%;一般区主要分布在整个阜阳市的中东部,占36.06%;退化区分布在颍上县和颍东区的中东部,占14.25%。

With the development of urbanization and industrialization, many problems are brought in to the society besides many profits, and the deterioration of the urban ecological environment becomes one of the problems people concern about.In this paper, taking Fuyang as an example, the present ecological environment of Fuyang and the environmental problems existing in the citywere analyzed, and the evaluation index system was constructed, selecting 21 indices to assess the ecological environment of Fuyang. Its weight is determined by analytic hierarchy process(AHP). Spatial distribution map of ecological environment evaluation grade in the city of Fuyang was determined by GIS spatial overlay analysis. The results show that: high quality and good area were distributed in Taihe, Linquan and most of Yingzhou District, accounting for 49.69%, the general area was mainly distributed in the Middle East of Fuyang City, accounting for 36.06%, the degraded area distribution in Yingshang and east of Yingdong District, accounting for 14.25%.
