Abstract
The dynamics of the ecosystem service value were evaluated by using the database of land use during 1997 ~ 2006 and Constanza estimation methods. The results indicated that the ecosystem service value has been rised due to the land use change in in the past 9 years. The total ecosystem service value in the study area rised from 2.532 billion yuan to 2.573 billion yuan in period of 1997 ~ 2006. There was 1.63% net increase of 0.41 billion yuan. But the ratio of ecosystem service value and GDP decreased year after year, which indicates that the the growth rate of ecosystem service value is less than economic's, and the development of ecological environment is positive. However, the efforts of improving the ecological environment is not good enough, which need to be further strengthened. On the basis, we should strengthen the measure of protective and constructive water conservation forest area, natural pasture and arable land, reasonably control the expansion of urban construction land, as far as possibly enhance Liangzhou District ecosystem service function.关键词
