Study On The Ecosystem Service Value With Its Change In Highway Region

This paper studied on the part of the JingCheng Expressway phase II area, from the ecosystem service value evaluation point,interpreted the three times image data which provided from RS platform, including the data before of highway built, the data in the highway completed and the data after the highway operation three years, created the LUCC database and through improving on the ecosystem service value evaluating mode ever, found the ecosystem service value evaluating mode which is fit for the study area,and using it got the three times ecosystem service value about the area. At last, this paper had done a research about the study area ecological environment which focused on the time of before the highway found and the time of the highway completed from the change of the LUCC and the ecosystem service value, and had a discussion about the ecological disturbance affected area through the result. The conclusion followings:1. On the research of the ecological disturbance affected area, because of the more artifical factors, the biological species composition is simple, the area biodiversity index is small, so the range of influence of the highway is very little, about three kilometers.2. The study area ecosystem service values mostly consist of forest ecosystems’ service value, farmland ecosystems’ service value and aquatic ecosystems’ service value, these three parts share of more than95%. The ecosystem service value is up to the ecosystem and the zone WTP(willingness to pay).3. After building of the highway,there is a growing about the ecosystem service value, because of the highway location advantages which made the planting structure changing towards to the side of ecosystem service value increasing,for example, the forest area in2009is1370.67hm2more than2000, the economic forest area increased obviously, the farmland area is reducing everyyear,with the exception of city construction using,a part of which changed to the garden which has high economic value of the sight-seeing farms.
