Evaluation and Change Analysis of Ecosystem Service Value of China's Northeast Tiger-Leopard National Park Based on Big Data Land Use Change.

The aim of the construction of Northeast Tiger-Leopard National Park is to protect the integrity of endangered wild animals and natural resources. There is a close relationship between land use and ecosystem service value. Improving the quality of ecological environment is the demand of ecological civilization construction. Therefore, this paper aims to evaluate and analyze the ecosystem service value of Tiger and Leopard Park, which is particularly based on big data land use change. Firstly, using ArcGIS software as the support, we have discussed the impact of the dynamic trend of land use change, transfer matrix, and sensitivity coefficient on ecosystem services in different periods of Tiger and Leopard Park. Secondly, we constructed an evaluation model based on the ecological service value method, which is primarily based on geographical conditions and surface coverage. We have completed the value evaluation and change analysis of ecosystem service in Tiger and Leopard Park by analyzing the generation process of ecosystem service data and information characteristics, as well as the ecosystem classification standard of Tiger and Leopard Park and equivalent factor of ecosystem service value per unit area. Simulation experiments show that the method proposed in this paper can reflect the service value of the ecosystem of the Tiger and Leopard Park, lay the foundation for the construction of ecotourism, and promote the green and sustainable development of the regional ecosystem of the Tiger and Leopard Park.
