摘　　要：针对城市生态系统健康评价标准的不确定性和不完整性,参考国内外园林城市和生态城市,建立评价指标体系,运用熵权法计算评价指标权重,根据属性理论构建评价模型,并对六盘水市的城市生态系统健康进行评价。结果显示,六盘水市生态系统的自然子系统属性属于亚健康状态,健康度值为2.837 7,社会子系统属性属于不健康状态,健康度值为2.784 5,经济子系统属性属于亚健康状态,健康度值为2.963 9,城市生态系统健康综合属性为亚健康状态,健康度值为2.841 6。通过分析,找出影响六盘水市生态系统健康的限制因素及其成因,为六盘水市的城市规划提供了参考依据。Due to uncertainty and imperfection of the evaluation criterion, this study tries to establish a series of the health assessment of urban ecosystem. By means of the entropy weight method, the study calculates the weight of assessment criteria, in order to construct the health assessment model of urban ecosystem based on the attribute theory. Then we do a case study of the model and methods to analyze the ecosystem of Liupanshui city. The evaluation results show that the natural subsystem and the economic subsystem and the urban ecosystem are sub-health, with the health value of 2. 837 7,2.96a 9 and 2. 841 6, respectively; and the social subsystem is ill-health with the health value of 2. 784 5. Depending on the results and the limiting factors and causes,the paper＇s purpose is to provide the scientific reference basis for urban planning and ecological livable city construction and ecosystem health management of Liupanshui city.
