摘要

[目的] 评价焦作市城市生态系统健康动态

以便进一步提高焦作城市生态系统健康水平

优化经济结构

确保污染物的持续减排。[方法] 以综合性、代表性、可比性和可操作性为原则

结合国家生态文明建设和节能减排形势要求

从活力、组织结构、恢复力、生态系统服务功能及人群健康5个要素入手构建焦作城市生态系统健康评价指标体系;采用熵权法确定权重

从时间序列角度评价健康水平的相对状况。[结果] 2006-2012年焦作城市生态系统健康水平逐年提高

活力和人群健康指数不断增加

组织结构指数小幅波动

恢复力和服务功能指数显著增加但显现波动。其中

经济结构变动是组织结构小幅波动的原因

污染物排放量和固废综合利用率的变化是城市恢复力及服务功能变化的主要因素。[结论] 优化经济结构

确保污染物的持续减排是提高焦作城市生态系统健康水平的关键。

Abstract

[Objective] To evaluate the urban ecosystem health of Jiaozuo City in order to further improve the level of the city ecosystem health

optimize the economic structure

ensure the continuous reduction of pollutants emissions. [Methods] Considering indices's completeness

representativeness

comparability

maneuverability

as well as the new situation of emissions reduction and ecological civilization

the assessment indices system of urban ecosystem health of Jiaozuo City was put forward

which contains five aspects: vigor

organizational structure

resilience

ecosystem service and population health of urban ecosystem. The health state of Jiaozuo city during 2006-2012 was evaluated with the entropy-weight method. [Results] The health state of urban ecosystem of Jiaozuo City kept improving during 2006-2012

and the indices of vigor and population health of Jiaozuo City increased steadly. Although the indices of resilience and ecosystem service of urban ecosystem had fluctuated

that increased significantly during the study period. The variation of economic structure caused in a small fluctuation of organizational structure. The changes of pollutant emissions and utilization rate of solid waste were the main reasons to cause the variety of resilience and ecosystem service of Jiaozuo City. [Conclusion] To improve the level of urban ecosystem health of Jiaozuo City

it should optimize economic structure and ensure the continous reduction of pollutants emissions.
