Application of Eco-service Value Theory to Environmental Impact Assessment of Land Use Planning
The purpose of this paper is to evaluate the environmental impact of the implementation of General Plan for Land Use in Taiyuan (2006-2020). The research is carried out based on the eco-service value theory. Firstly, area change of each land use ecosystem before and after the implementation of the Plan is comparatively analyzed; and then on the basis of former researches, the unit eco-service value of each land use ecosystem is modified combining with the local situation of Taiyuan; finally, the total eco-service values both in 2005 and 2020 are calculated and sensitivity analysis is made to test the accuracy of the eco-service value coefficient and confirm the estimated results. The studies indicate that the eco-service value of Taiyuan will increase by 17.08%, mainly due to the significant area growth of garden plot and woodland, which have relatively high eco-service value. Thus it can be concluded that General Plan for Land Use in Taiyuan (2006-2020) is practicable, and it will contribute to the local sustainable development.
