Abstract

Abstract: 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, CO₂ fixation, O₂ release, nutrient recycling, water conservancy and water supply and SO₂ degradation were 1.51?10⁷, 4.77?10⁷,3.63?10⁷, 4.45?10⁵,1.10?10⁸, 5.15?10⁵ yuan穣r^-1,respectively. The sum was about 2.24?10⁸ yuan穣r^-1.From the above incomplete estimation,it was known that the Baoan Lake ecosystem has great ecological and economic values.
