基于GIS的中国城市水环境管理研究现状与趋势分析

随着中国城市规模迅速扩大、人口急剧增加,给城市水环境造成了巨大压力.由于绝大多数水环境信息是与空间位置关系密不可分的,在使用传统管理信息系统以及数据统计方式处理大量的水环境数据时,并不能很好地利用与呈现空间特征,因此,具有地理空间分析功能的地理信息系统（GIS）逐渐受到重视.然而,目前GIS在城市水环境管理中仍存在需要思考和改善的地方,以形成完整的城市水环境决策系统,提出可用的环境改善建议.

Review of GIS-Based Domestic Urban Water Environment Management

With the expanding of city scale in China,the population grows rapidly.This has caused enormus pressure to the urban water environment.Most of the water environment information is inseparable with its spatial information,while traditional management informtion system cannot make a good use of its spatial features.As a result,geographic information system（GIS） which has a geographical spatial analysis function is receiving more and more attention.On the other hand,although GIS has been widely used in the management of domestic urban water environment,there are still many problems to deal with to build up a comprehensive decision-making system of urban water environment.This study puts forward some useful suggestions.
