Abstract:

The ecological services value is one of indexes to measure all services functions of ecosystem. In this paper, the value is employed to express the effect of the ecological services function. On the basis of the theory of ecosystem services function, the decrease of the ecosystem services function caused by land use/cover change (LUCC) is regarded as ecological risk in this paper. Then, a quantitative analysis is used to examine ecological risks that the various stakeholders may face in the context of LUCC. The stakeholders mainly refer to the land owner or the operator (individual, community and country) in this study. The research shows that, during the period of 2000-2006, the service function values had increased 28.91% in the Yan River basin, mainly due to the implementation of the policy of grain for green. The analysis designed for different stakeholders in the context of LUCC indicates that the ecological services values for the individual, community and country were increased by 34.71%, 33.64%, 14.57% between 2000 and 2006, respectively. The main ecological risks include two aspects. One is that the capacity of obtaining foods for individuals was decreased by 5.71%, and the other is that the biological control for the country dropped 24.56% during the same period.
