摘要
随着生物资源价值估算方法的日益成熟 ,生态系统的服务评估成为生态系统研究的热点 .鉴于国内对于湖泊生态系统的服务评价的研究较少 ,本文运用生态系统学与生态经济学方法研究了湖北保安湖生态系统的部分生态服务 .计算得到 1992年保安湖水生态系统有机质生产价值为 15 14 .93万元 ,固定CO2 的价值为 4 772 .99万元 ,释放O2 的价值为 36 2 6 .5 3万元 ,主要初级生产者储存N、P的价值为 4 4 .4 8万元 ,而年吸收量的价值为 15 0 7.99万元 ,调蓄和供水的价值为 10 92 8.93万元 ,消除排入湖水SO2 价值为5 1.5 0万元 ,合计 2 .2 4× 10 8元 .据不完全估计 ,可以认为 ,生态系统具有巨大的生态经济效益。
Along with the maturation of estimation methods for biological resources, the studies on the services value of ecosystem become a hotspot in ecology.The studies on the services value of lake ecosystem were not been reported before this issue, and this issue firstly attempted to estimate the Baoan Lake ecosystem services and its indirect economic values on the basis of ecological function analysis and some economic methods.The results showed that the indirect economic value (in RMB) of organic matter production, CO 2 fixation, O 2 release, nutrient recycling, water conservancy and water supply and SO 2 degradation were 1.51×10~7, 4.77×10~7,3.63×10~7, 4.45×10~5,1.10×10~8, 5.15×10~5 yuan·yr~ -1,respectively. The sum was about 2.24×10~8 yuan·yr~ -1.From the above incomplete estimation,it was known that the Baoan Lake ecosystem has great ecological and economic values.
