摘　　要：将生态位适宜度理论引入到城市人居环境质量定量评价中,并据此构建城市人居环境质量定量评价的生态位适宜度模型。利用该模型选取24项反映现实生态位与最佳生态位之间耦合度的单项指标,构成经济生态位、社会生态位、环境生态位三大类独立的评价指标,用以评价城市人居环境质量。同时,以浙江省9个地级城市为例,运用所建模型对这些地级市的城市人居环境质量进行了评价,结果显示,2004年城市人居环境质量杭州最高,温州最低,其中经济生态位对我省城市间人居环境质量差异的影响最大。本研究表明,生态位适宜度模型对于多指标的城市人居环境质量定量评价,不但可以定量地研究各个区域城市人居环境质量的生态位适宜度,还能简明直观地揭示引起人居环境质量的生态位适宜度区域差异的主导因素和空间分异规律,从而为决策管理部门制定城市规划方案提供理论依据。The study introduced the niche fitness model into the quantitative evaluation of the environment quality of the urban human settlement, establishing the niche fitness model for the quantitative evaluation of the environment quality of the urban human settlement, with 24 monomial indexes selected to constitute 3 independent indexes of evaluation. As a case, the model was applied to evaluate the environment quality of the urban human settlement of 9 cities of Zhejiang Province, and the result was that Hangzhou city was best, Wenzhou city was worst, and the economic niche had the most influence on the difference of the environment quality of the urban human settlement between cities of Zhejiang Province. The result showed that this model was scientific and effective for the quantitative evaluation of the environment quality of the urban human settlement.
