张家界市生态系统服务价值时空变化及权衡协同关系
Spatio-temporal Changes and Trade-offs and Synergies of Ecosystem Service Values in Zhangjiajie City
摘要
Abstract
The analysis of trade-offs and synergies,as well as spatio-temporal changes in ecosystem service,serves as a crucial basis for guiding regional environmental protection and ecological construction.Based on a revised equivalent factor table,this study investigated the ecosystem service values and their spatio-temporal changes in Zhangjiajie City from 2002 to 2018.The model of ecosystem service trade-off and synergy degree was introduced to analyze 9 ecological service functions.The results showed that during the study period,the ecosystem service value in Zhangjiajie City decreased from 29.018 39 billion yuan in 2002 to 28.985 30 billion yuan in 2018,with a reduction rate of 0.114 0%,showing a fluctuating trend of first increase and then decrease.The trade-offs and synergies revealed that the dominant relationships among ecosystem service functions in Zhangjiajie City exhibited a trend of synergy to trade-off and back to synergy from 2002 to 2018.关键词
