摘要
以泉州湾河口湿地为研究对象,结合服务指标分类和去重复计算,采用市场价值法、替代价值法及机会成本法等,对泉州湾河口湿地1997、2005、2013、2015年的生态系统服务价值进行了动态评价,并采用逐步回归分析法、通径分析方法探讨服务价值变化的主要驱动因子及其作用途径和强度.结果表明:泉州湾河口湿地的主导服务为调蓄洪水、气候调节及食物供给服务;对泉州湾河口湿地生态系统主导服务价值变化直接影响最大的因子分别为供水量、海水养殖量和地区生产总值,其他驱动因子则通过间接影响作用于服务价值的变化.
Ecosystem service value(ESV)in 1997,2005,2013 and 2015 of Quanzhou Bay estuary wetland was evaluated dynamicly by market value,alternative value and opportunity cost methods,combined with classification of service indicators and deduplicate computing.The main driving forces for the changes of ESV and the pathway and intensity of their actions were identified using stepwise regression and path analysis methods.The results showed that the main ecosystem services of Quanzhou Bay estuary wetland were flood regulation,climate regulation,and food supply,which were directly driven by water supply,mariculture carrying capacity,and gross value of the regional production.Other drivers exerted indirect effect on the changes of main ESVs.
