摘  要：
以北京市门头沟区为例,分别基于森林资源二类调查数据和遥感解译的土地覆被数据,利用In VEST模型,对研究区内主要生态系统服务的大小和空间分布进行量化和描述。结果表明:森林资源二类调查数据可以与InVEST模型结合用于区域生态系统服务的计量,且与基于遥感数据的评估结果相近;门头沟区总碳储量平均为1 525.05万t,产水量为2.93亿m3/a,N和P保持量分别为112.94 t/a和0.39 t/a,N和P输出量分别为28.89t/a和0.09 t/a,土壤保持量为1.65亿t/a,土壤侵蚀量为51.39万t/a;从空间分布看,植被覆盖好的区域具有较高的碳储量和土壤保持量,N和P保持量与集水区内农地、裸地比例密切相关,产水量则受土地利用/覆被组成和降水分布格局的影响。

摘  要：
In this study,the magnitude and spatial pattern of main types of ecosystem services in Mentougou District,Beijing were evaluated based on In VEST 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 In VEST 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.
