In history, Mentougou District had been conducted a large-scale mining and industrial and agricultural activities. Then with the influence of urban construction expansion and tourism development, the ecological environment of Mentougou District had been severely disrupted which with combined effects of natural disasters, so it is beyond doubt that the Mentougou ecological protection and restoration can not be ignored at present. According to "BEIJING Municipality Master Plan (2004-2020 years)", Mentougou District is orientated to the eco-conserving division. As a key conservation area to maintain a good environment for Beijing, Mentougou District plays an important role of ecological barrier in ensure a sustainable development in Beijing Municipality. Accordance with this functional position, the ecological rehabilitation investment has increased year by year at all government levels in Mentougou District, which making the area in a transformation process from the mineral resource-orientated area to the eco-conserving division. Great changes in industrial structure and function orientation in Mentougou District have taken placed and the ecological rehabilitation benefit has appeared.The issue from the perspective of economic research, systematic combing of different ecological restoration mode Mentougou generated ecological, economic and social benefits, construction comprehensive benefit science of ecological restoration Assess the theoretical model and accounting frame, and the region's typical project to account for the government to provide a convincing theoretical basis and reference data. Through the study of this issue, the scientific evaluation of the services Mentou gou value of ecological systems, for the full understanding Mentougou ecosystems in the Beijing area the value of ecological services provided, led up scientific and reasonable ecological protection of vegetation and ecological compensation mechanisms to more effective play Mentougou of ecosystem services is of great significance. Ecological restoration is not only the ecological benefits, social benefits and other indirect economic benefits, such as water conservation value, the value of soil conservation, biodiversity conservation value, the value of air purification, climate regulation value of the region, as well as travel watch efficiency, and increase employment direct economic benefits. In this study based mainly on forest ecosystems, ecosystem services on Mentougou landscaping benefits, convalescent care benefits, increase employment and improve the progress of social civilization and other social benefits to be evaluated.By calculating, we know the Mentougou ecological restoration of land to bring the comprehensive benefits of annual value is 427.61 million yuan. Of which:Ecological benefits of 283.41 billion/year,66.3%of total benefits;Cost 93.79million/year,21.9%of total benefits; social benefits of 50.41 billion/year,11.8%of total benefits.GDP 67.8 billion in 2008 compared to the region, the region accounted for 6.31%of GDP, and the region in 2008 compared to financial income 890 million yuan, accounting for 48.05%of fiscal revenue region, accounting for annual district revenue half.Ecological restoration of ecosystem services generated far greater than its economic function.According to the information Mentougou, In the 2005-2009 five-year period, Mentougou ecological restoration has invested 1.2 billionThe average annual investment of about 2.4 million, the combined benefit is greater than current year's investment.Therefore, the ecological restoration work is benefits to the present, livelihood projects to benefit children and grandchildren and public welfare undertakings.This paper derived Mentougou area ecosystem services of great value, The ecosystem services is far greater than its economic function, Mentougou ecosystems also have great social benefits, for landscaping, convalescent care, promotion of employment, improvement of social civilization of great value. Therefore, the strengthening of the Mentougou ecosystem protection is of great significance. At the same time as population growth and economic development, Mentougou will further increase pressure on the ecological environment, the Mentougou ecological functions undertaken in Beijing far more than its economic function. Therefore, the improvement of ecological environment protection, the establishment of resource-saving system of social production and consumption, for ease the contradiction between people Mentougou, Ecosystem services play better, it is extremely urgent. Therefore, to avoid over-exploitation and the general development of the development model Effective means of ecological protection, Ecosystem services for Mentougou continued to play.
