摘　　要：在总结城市生态系统的属性并分析其健康内涵的基础上,通过频度统计法,建立评价指标体系。采用海明贴近度,建立模糊物元模型,对河南省第一批水生态文明城市建设试点郑州、洛阳、许昌2000年-2013年间城市生态系统的健康水平进行评价,分析影响城市生态系统健康发展的各要素,结果表明:郑州、洛阳和许昌整体的城市生态系统健康水平呈上升趋势,但健康改善程度并不显著,且部分指标有恶化趋势;相同时期内,城市生态系统的健康水平排序由高到低依次为郑州、洛阳、许昌,但其增长速率则为许昌最快、郑州最慢;各城市不同要素之间的健康程度差别较大,且不同城市各要素之间的协调性较低。因此,未来应针对健康程度较差的要素重点发展,提高各要素之间的协调性,进一步提高城市生态系统整体的健康水平。On the basis of summarizing the attributes of urban ecosystem and analyzing its content of health,an evaluation indicator system was established using the frequency statistics.A fuzzy matter model was then developed using the Hamming approach degree to estimate the urban ecosystem health in Zhengzhou,Luoyang,and Xuchang(the first batch of the experimental units of water eco-civilization construction in Henan Province)from 2000 to 2013and analyze the impact factors of urban ecosystem health.The results showed that(1)the level of urban ecosystem health in Zhengzhou,Luoyang,and Xuchang is improving slightly,but some indexes tend towards worse;(2)the level of urban ecosystem health from high to low is Zhengzhou,Luoyang,and Xuchang,but the improving rate in Xuchang is the highest while the lowest in Zhengzhou;and(3)the health degree differs in different cities and the harmony between each index is low.Consequently,we should focus on the development of indexes with low health degree,improve the harmony between each index,and increase the health level of urban ecosystem.
