Abstract: This paper studied characteristics of land use change and ecosystem services value in the middle reach of Shulehe River in 1990-2010, based on ecological economics theory and by using ArcGIS 9.2 and ERDAS 9.1 software and the calculation formula of Costanza et al., in combination with the China terrestrial ecosystems services value per unit area. In 1990-2010, the dominant land use types in the study area were unused land, grassland, and cultivated land, occupying 98.2% of the total, and the overall land use characteristics had no significant change. The land use change mainly occurred in cultivated land,built-up land, and grassland, and the dynamic degree was 13.6%, 8.0%, and 7.7%, respectively. The ecosystem services value presented an increasing trend, from 344.85 billion Yuan increased to 485.11 billion Yuan. Grassland and water area contributed most to the total ecological services value. The ecological and economic development in the study area was at the margin of low level coordination, and thus, protection efforts on the ecological environment should be further enhanced.
