Assessment on the eco-service value in karst rocky desert:A case study in Jinsha County
摘要
Abstract
In order to set up a method which is suitable for assessing the eco-service value in karst region,and then provide data for assessing the benefit of karst rocky desertification comprehensive management project in the future,the eco-service value evaluation system is put forth in Jinsha County on the basis of former studies at home and abroad.Furthermore,4 dominant functions including organic matter production(SOM),CO2 fixing and O2 release(CFR) and soil and water conservation(SWC)as well as landscape and recreation (LR) are selected for estimating the eco-service value in forest land ecosystem,farmland ecosystem and grassland ecosystem as well as unutilized land ecosystem in Jinsha County.The results show that,from 2005 to 2010,the eco-service value of the four ecosystems in Jinsha County decreased by 16.2 thousand yuan/km2,the total eco service value decreased 36.07 million yuan,which is 0.42 % of the GDP of the Jinsha County in 2010,and among them,the function of SOM decreased 32.32 million yuan,the function of CFR decreased 23.25 million yuan,the function of SWC increased 16.15 million yuan,and the function of LR increased 3.35 million yuan.关键词
