城市住区水景生态评价指标体系的构建

住区水景建设是城市人居环境建设的重要内容之一。城市住区水景生态评价作为人居环境基础工作,其根本任务是建立一套科学、合理、具有可操作性的评价标准和指标体系,从生态学的角度对现有的住区水景建设进行合理评价,揭示现存的问题和确定其将来发展的方向,为住区水景规划与设计提供依据。本文提出了住区水景建设指标体系筛选、设计的五个主要原则,并从自然度、自净(健康)度、景观度、节水度、亲水度五个方面制定评价的具体指标,建立了城市住区水景生态评价指标体系。

Construction of the Ecological Evaluation Index System of Water-scape in Urban Residential Community

The construction of waterscape is oneoft he important contents of environmental con-struction of the urban residential community. Asbasic work of residential communityconstruction,t he basic task of ecological evalu-ation of waterscape in urban residential com- munity is to set up a set of scientific, rationaland effective evaluation criterion and indexsystem, build rational evaluation to the exist-ing waterscape in residential community interms of ecology, bring the extant problems tolight and confirm its direction of developmentin the future. All this will provide basis onwhich the waterscape is planned and designedinr esidential community. Five main principlesabout how to select and design the evaluationindex system of waterscape in urban residen-tial community are put forward in this paper,concrete indexes were established on the basisof five respects which are naturalness degree,self-purificatory degree, landscape degree,economizing on water degree, and hydrophilicdegree. Thus the ecological evaluation indexsystem of waterscapei n urban residential com-munity was constructed.
