摘要

Wetland is an important part of the ecological system. It has an important role in soil erosion prevention. Without the protection of wetland, soil erosion will cause two aspects physical loss, including 1) the waste land caused by soil degradation and desertification; 2) nutrient contents loss. This paper takes all wetland in Beijing as object. This research includes investigation and research on indexes of soil erosion prevention in Beijing wetland ecological system. Two aspects of reduction soil waste and prevent soil fertility are studied. Potential and actual soil erosion are calculated using GIS and universal soil erosion equation based on collected data, with the difference of the two amounts is the soil conservation quantify, which will be converted to economic value. Research results show the economic value of Beijing wetland in the soil erosion prevention is 4,962.56 million Yuan. The river and swamp have the highest value; meanwhile, the rural wetland's value of soil erosion resistance is more than in the urban area. Wetland has the extremely vital significance to keep a good ecological environment in Beijing.
