摘　　要：以中国辽西北地区煤炭资源型城市阜新市为研究对象,对该市生态环境特点进行了分析。采用层次分析法和生态环境容量指数法,建立了生态环境容量评价指标体系及评价权重,计算了生态环境容量现状值,并对该市当前所处的生态环境状态进行了评价。结果表明,阜新市目前的生态环境容量评价值为0.316 7,属于生态环境容量分级标准中的第4级,说明阜新市当前的生态环境容量处于较低状态,自然生态系统承载能力已经接近极限。这与城市多年来的煤炭开采活动密不可分。未来应关注经济开发活动和自然生态环境的协调发展,从而改善城市生态环境,促进城市可持续发展。Taking Fuxin City of Northwest Laioning Provincd as a study object of typical coal-based city, the paper made an evaluation on the ecological environmental situation through establishing an indicator system of ecological environmental evaluation and calculated the capacity value of the ecological environment by adopting the methods of analytic hierarchy process（AHP） and ecological environmental capacity index. The result indicated that evaluation value of the present ecological environment capacity in Fuxin is 0. 316 7, which fell into the fourth grade of the ecological environment capacity grading standard and showed that the current ecological environment capacity of Fuxin City is at relatively low level, its carrying capacity of natural ecosystem is close to its limit and is inseparable from the long time coal mining activities of Fuxin City, there-fore attention should be paid to the coordination of economic development and natural ecological environment to improve the environment of the city and prompt the sustainable development.
