Abstract

The ecological system service is closely related to the citizens' welfare and serves as the bridge connecting the ecological system and the social system. To achieve sustainable development, we must protect the ecological environment. The paper marks off different land utilization types of the Lijiang River basin based on the remote sensing technique, and borrows ideas from other research findings and combines the practical situation of Lijiang River basin to correct the service unit price of ecological system type of the Lijiang River basin, then calculates the service value of ecological system for the basin in turn. The findings show that the total value of the service function of ecological system for the Lijiang River basin is 7195.22×10⁶ Yuan. In terms of the service function of the ecological system, the woodland's service function value accounts the largest proportion in the whole ecological system, being 85.26% of the total value. In terms of the service function type of the ecological system, the soil formation and protection are the most significant, with value of 1340.00×10⁶ Yuan, which accounts for 18.62%. The ecological service value's sequence in ascending order is: Food production <entertainment culture < raw material < waste disposal < climate regulation < gas conditioning < biological diversity protection <headwater conservation < soil formation and protection. The research is of important theoretical guidance and practical meaning for the monitoring over the ecological environment of Lijiang River basin and the sustainable development of tourism.
