基于模糊综合评判法的城市森林健康评价——以湖南省株洲市为例

Urban forest eco-system health assessment based on fuzzy synthetic appraisal: Taking Zhuzhou city, Hunan as an examplc

在建立城市森林生态系统健康评价指标体系的基础上,以AHP法求得各个指标权重,再建立模糊综合评价模型,对株洲市荷塘、芦淞、天元、石峰4区的城市森林生态系统进行实证评价分析.结果表明,株洲市4个区的城市森林生态系统健康状况分别为不健康(评价值为0.3594)、不健康(评价值为0.3708)、不健康(评价值为0.3698)和良好健康(评价值为0.7833),评价结果与当地实际情况相符.

Based on the index system of health assessment of the urban forest ecosystem, the weight of each index was obtained by AHP method, and then the modal of fuzzy synthetic appraisal was established to evaluate it. An empirical analysis was conducted on the four areas： Hetang, Lushong, Tianyuan and Shifeng in Zhuzhou city, with the result of the urban forest ecosystem health appraisla, unhealthy （value, 0.359 4）, unhealthy （value, 0.370 8）, unhealthy （value, 0.369 8） and good health （value, 0.783 3）respectively. The result agrees with the reality.
