摘要
本文以深圳市福田自然保护区红树林为例,基于压力-状态-响应(PSR)模型构建了深圳红树林湿地生态系统健康评价体系,并根据熵权法和GM(1,1)模型计算深圳市红树林2008-2018年的综合生态健康指数(CHI)。结果表明:深圳市福田红树林生态系统的综合健康指数(CHI)呈现波动上升趋势,表明红树林生态系统为亚健康状态,个别年份的生态系统综合生态健康指数出现下降,但从整体上看综合生态健康情况呈现良好发展的趋势。
Mangrove in Shenzhen Mangrove Nature Reserve is taken as an example. Based on PSR model,health assessment system of mangrove wetland ecosystem in Shenzhen was constructed. After calculating the indicator by entropy method and GM( 1,1) model,annual ecological health index of mangrove in Shenzhen from 2008 to 2018 was figured out. The results show that the CHI of mangrove ecosystem in Shenzhen presents a rising tendency with fluctuation,implying the subhealth of mangrove ecosystem. Meanwhile,comprehensive ecological health condition shows a good development trend,though Comprehensive Ecological Index in some years declined.
