摘要： Water conservation is one of the important ecological service functions of ecosystem. Time series LandSat images were used to analyze the change of spatial pattern of ecosystem in recent thirty years. Four types of ecosystems including farmland, forest, grassland and water were mapped, which had the function of water conservation. The water conservation function of ecosystem is similar to storing water of reservoir. The expense substitution method was used to calculate the service value of water conservation of ecosystem. The average cost of constructing the reservoir was substituted to evaluate the service value of water conservation function of ecosystem. Results showed that the ecological value of water conservation in Beijing area in 1978 was highest among four years, while that in 2000 was lowest. The fluctuation of water storage of ecosystem was consistent with the precipitation. The main contributors of ecological value of water conservation were forest and farmland. Because the government was committed to promoting the percentage of forest covering, the forest was the stable contributor for water conservation in Beijing area.
