Abstract

This study investigated estimation on ecosystem services value based on food production in Xinjian County of Nanchang City, East China. We used two Landsat TM data sets (1996, 2004) to estimate changes in the size of seven land use categories and we used the most recently published value equivalent to estimate changes in the values of ecosystem services. The total value of ecosystem services in Xinjian County was 4588.2 million Yuan in 1996 and 4587.8 million Yuan in 2004, with a decrease of 340.8 thousand Yuan mainly due to the relatively biggish decrement in values of ecosystem service functions for waste treatment, hydrology regulation and food production, although the values for all the other six ecosystem service functions showed an escalating trend from 1996 to 2004. We concluded that future local land use plan should give priority to the conservation of these reductive ecosystems, in order to promote and maintain the balance of local ecosystem.
