摘要

Variation in ecosystem services value across land-use scenarios in Fuxin City of Liaoning Province were explored in the study. Two-period land use survey data (1996 and 2010) were used to estimate changes in the size of seven land use categories and the most recently published value equivalent was used to estimate changes in the values of ecosystem services. The total value of ecosystem services in Fuxin City was 17674.75 million Yuan in 1996 and 19077.59 million Yuan in 2010, with an increase of 1402.84 million Yuan mainly due to the inclining areas of forestland and grass land, which indicated the eco-environment in Fuxin City has been becoming better and better. However, agricultural land including farmland and orchard showed the tendency of decrease, which indicated food security has been facing with challenge in Fuxin City.
