In the ecological environment, it is mainly reflected in the service and comprehensive evaluation of the ecosystem. The entire system of the INVEST algorithm model can simulate and predict the quantitative and qualitative ecosystem service value under various land use conditions, which can play a role in the decision-making of environmental management. The INVEST algorithm is mainly used to evaluate the service function and economic value of the ecosystem. For example, eco-tourism, soil and water conservation and protection of pupils, etc., to ensure the overall role and impact of human activities on the ecosystem. This study is based on the InVEST algorithm model in the construction and protection of mountain ecological environment, and provides a reference for the development and decision-making of related industries.
