| Taking Hilly Region of Central-Southern China, Liling city as an example, This paper analyzes the land--use types and the spatial patterns of land use,which is based on the Landsat TM data and the actual conditions. Effects of land use change on ecosystem service value in liling from 1996 to 2008 were studied by applying the table of Chinese land ecosystem services value of unit area,the ESV computing formula and ESV coefficients. Results showed that: the land use change is mainly reflected on the decrease of cultivated land and waters area as well as the increase of wood land and construction land, among which construction land has the biggest increse, it increases 4038.81 ha. Although the value of ecosystem services arising from land-use change caused by the value of the coefficient differences is to offset each other, the value of ecosystem services in Liling cityisreducedto84,235,300yuan from 1996 to 2008; Looking from the ecosystem service value in spatial, most villages of Liling decline in different degrees on it, the reduced regions are mainly along the towns and urban city of Liling. Through the prediction of gray GM (1,1) model, the total value of ecosystem service in Liling city will be 4,979,653,300 Yuan in 2014 and 4,936,338,200 Yuan in 2020, its tendency is dropping. Based on the above research, recommendations are proposed in the paper to protect eco-environment in Liling city,which provides references for sustainable utilization of natural resources and eco-environmental protection. |
