Abstract:

Along with the maturation of estimation methods for biological resource value，the study on the service value of ecosystem becomes a hotspot in ecological field.Through using market value method,shadow engineering approach as well as carbon tax method and so on,this paper attempts to estimate both direct and indirect values of Taihu wetland such as organic matter function,environment regulation function and culturesocial function.The results show that Taihu Lake wetland possesses huge and multiple ecological services value, which is about 11239×108 Yuan in all.Taihu wetland has the greatest value in the function of the environment regulatory,accounting for 4898% of the total.The organic matter production and water supply account for 291%.The culturesocial function has the least value,accounting for 2191%.The result of evaluation of 9 subfunctions shows that the most important function is flood regulation which is about 2623% of the whole value.The second is water supply,accounting for 2456% and the third is climate regulation,accounting for 1823%.This study first asseses the value of Taihu wetland ecosystem service from the quantitative prospection.The findings of this study play a significant role in recognization the value of various ecosystem service of Taihu wetland and providing reasonable direction to the protection.
