A Value Assessment Algorithm for Ecological Protection of Zhangjiajie National Forest Park Based on Ecosystem Service Assessment and Ecological Benefit Models

This paper introduces the methods and principles of the ecosystem services and ecological benefit models, constructs a value assessment model for ecological protection of Zhangjiajie National Forest Park, proposes a value assessment algorithm for ecological protection of Zhangjiajie National Forest Park, and finally carries out discusses and analyses. The results of the study show that algorithms that use ecosystem services and ecological benefit models to assess the value of ecological protection of national forest parks all assume that the current situation scenario market and dynamic changes, internal functions, and different willingness to pay are interrelated; the conclusions they draw are also instantaneous, however, the impact of various aspects of the forest on the park ecosystem, which is reflected in the ecological benefits of the park, is constantly changing. This paper uses the simulated market technology to set up a value assessment algorithm that combines different scenario services and conditional value assessment in line with the future development model of Zhangjiajie National Forest Park. It can not only reflect the change trend of tourists' willingness to pay and be compensated for the ecological benefits of national forest parks under different scenarios in the future in the assessment area, but also can obtain the highest and lowest ecological benefit calculations with a certain elastic range that are integrated with different scenarios. This can be used to meet the dynamic requirements of the ecological protection of national forest parks, and provides a basis for determining the implementation standards of park ecological compensation.
