| 摘 要： | 人居环境生态适宜性评价是城市区域规划的基础,为了优化城市人居环境、科学地判定一个城市人居环境生态适宜性,本研究根据大连市实际情况,选取自然、人文和经济共20项指标,运用PSR环境评价模型构建了大连市人居环境生态适宜性评价指标体系,并采用熵权法和综合指数法对大连市进行了实证分析,计算出了2000—2010年的大连市人居环境生态适宜性指数.结果表明:2000—2010年大连人居环境生态适宜性状态总体上呈波动上升趋势;且目前已达到适宜状态.

| Abstract: | Ecological suitability assessment of human settlement is the basic of regional planning in city. In order to op- timize the urban human settlement, and judge ecological suitability of human settlement of a city scientifically, based on the actual situation of Dalian, this paper combined a total index of natural, humanity and economy together, makes it pos- sible to study on the human settlements with a holistic method, and set up an assessment index system of ecological suit- ability of Dalian＇ s human settlement, and analyzed Dalian for example by PSR-entropy weight method. The research re- suits showed that： at present, Dalian＇ s ecological suitabuity of human settlement has reached the suitable condition and Dalian＇s ecological suitability state of human settlement in 2000--2010 overally showed a trend of fluctuant rise. |
