文章在总结前人大量工作的基础上,探讨了杭州湾南岸互花米草盐沼的7种主要生态服务功能,并运用能值分析、市场价值、替代价格等多种评价方法对其生态系统服务功能的经济价值进行了评估。研究表明,杭州湾南岸互花米草盐沼生态服务总价值为1.045亿元。其中,直接经济价值为0.060亿元,间接经济价值为0.985亿元,间接经济价值是直接经济价值的16.42倍。
Based on analyzing many research about Spartina ahemiflora, the paper discussed S. alterniflo-ra＇s 7 ecosystem services in south coast of Hangzhou Bay. The methods of emergy analysis, market valuation and substitute expense were used to estimate the economical value of the ecosystem. The results show that the value of S. aherniflora ecosystem services is relatively higher. The gross economic value is 1. 045×10^8 yuan, in which, the direct value is about 6.00 × 10^6 yuan, the indirect value about 1. 642 × 10^7 yuan, and the indirect gross economic value is 16.42 times higher than that of the direct.
