A Study on the Value Change of Land Ecosystem Services in Huangguoshu Scenic Area

Land use and ecological service influence and constrain each other and the quantitative research on the value change of ecosystem services and land use in Huangguoshu scenic area can help to provide a scientific basis for the harmonious development of special ecology,society and economy in Huangguoshu scenic area. This paper analyzes the value change of land ecosystem services in Huangguoshu scenic area during 2009- 2012,and explores important issues and focus in the land planning and development of Huangguoshu scenic area. The results show that the value of woodland ecosystem services is highest in Huangguoshu scenic area,accounting for nearly 70% of the total value,and there was a slight decline in the total value of ecosystem services in Huangguoshu scenic area during the four years,mainly due to the internal restructuring of agriculture and expansion of construction land. In the future development of Huangguoshu scenic area,it is necessary to economically and intensively use construction land,pay attention to the maintenance and improvement of land ecological environment,and focus on the protection of woodland,pasture land and other types of ecological land,so as to improve the overall regional land ecosystem services.
