摘要
住区水景建设是城市人居环境建设的重要内容之一.不仅要注重经济效益,还应充分发挥其生态效益.建立相应的指标体系是对城市住区水景科学设计、建设和生态恢复的前提和基础.根据所制定的原则,利用主成分分析法和无重复双因素方差分析法筛选指标,用统计分析软件SPSS对各级指标值的隶属度值进行主成分分析、AHP决策分析法确定各级指标的相对权重、最终确定各指标权重.采用层次分析方法,从而建立一个三层次的评价指标体系.以上海52家住区为例,对各水景生态效益进行评价.结果表明:2/3水景处于三级以下,非生态的人工水景是影响上海住区水景生态效益发挥的关键所在.提出生态恢复和科学管理建议,即建设近自然型的住区水景.
Based on the proposed principles, this paper used principal component analysis and non-repeated two-way analysis of variance to screen the indexes of ecological benefits of waterscape in urban residential areas. Weight of each index at different levels was determined based on analytical hierarchy process decision analysis. Ultimately, a three-level evaluation system was set up using analytical hierarchy process. We applied this evaluation system to 52 residential areas in Shanghai. The result shows that about 2/3 of waterscapes are categorized into levels 3 to 5, and non-ecological artificial waterscape is the key factor that influences the ecological benefits of waterscape in residential areas in Shanghai. At last, we put forward a proposal for ecological restoration and scientific management, i. e. , the construction of close-to-nature waterscape in residential areas. Based on the evaluation approach for ecological benefits of waterscape in urban residential areas evaluation process is simple, useful and highly operable, Additionaly, evaluation resuhs are objective and reasonable. They reflect not only the state of ecological benefits of waterscape,but also the living quality of residents and water environmental management level of residential area.
