摘　　要：从城市生态系统健康概念出发,选取自然系统、经济系统和社会发展系统构建城市健康评价指标体系,采用基于熵值的赋权法来确定指标权重,运用模糊数学的方法对佳木斯城市生态系统健康进行评价分析。评价结果表明,佳木斯城市生态系统处于亚健康状态。根据佳木斯实际情况,提出了建议和解决途径。Based on the connotations of the health assessment of urban ecosystem, three indexes were selected to build an evaluation system, including natural systems, economic system and social development system. Applying the method of entropy value to confirm the index weight, the method of fuzzy mathematical models was used to analyze and evaluate the health of the urban ecosystem of Jiamusi City. The evaluation results indicated that the ecosystem of Jiamusi was in sub-healthy level. Finally, according to the actual situation of Jiamusi, some suggestions and solutions were put forward.
