Abstract: In this study,the magnitude and spatial pattern of main types of ecosystem services in Mentougou District,Beijing were evaluated based on InVEST model using forest inventory data and classified remote sensing data,respectively.The results showed that forest inventory data can be used to evaluate regional ecosystem services combining with the InVEST model.And the results based on the two sources of data were similar.The average carbon storage in Mentougou District was 1525.05×104 tons.The water yield was 2.93×108 stere.The N and P retention were 112.94 tons and 0.39 tons respectively.The N and P exports were 28.89 tons and 0.09 tons,respectively.The soil conservation was 1.65×108 tons,and the soil erosion was 51.39×104 tons.There were obvious spatial patterns in the distribution of ecosystem services.Areas with a high level of vegetation cover also had a high level of carbon storage and soil conservation.The distribution of N and P retention was related to percentages of crop and bare lands.The distribution of water yield was influenced by percentage of land use/land cover and spatial patterns of precipitation.

Key words: forest inventory data, carbon storage, water yield, N/P retention, soil conservation
