3. Application of InVEST model in human activities, major ecological projects, ecological protection and restoration benefit evaluation projects and thesis writing
The formulation of ecological policies such as major ecological protection and restoration projects, protection and development projects, such as the policy of returning farmland to forests, ecological protection policies, and adjustment of nature reserves, etc., all need to predict the ecological benefits after the project is implemented in advance. Through the method of scenario construction, the ecosystem service effects of different protection strategies or construction paths are evaluated and weighed, so as to obtain the optimal protection and development strategies.
4. Application of InVEST model in ecological protection policy and protection priority area selection projects and thesis writing
The ecological protection red line policy, the selection of conservation priority areas, the adjustment of nature reserves, and other related projects all need to further analyze the spatial distribution and quantitative characteristics of each ecosystem service index on the basis of evaluating the regional ecosystem services, and reveal the characteristics of each ecosystem service index. The trade-off and synergistic relationship of indicators; select the hotspot distribution area, conduct spatial superposition analysis on the hotspot areas of each indicator, and finally obtain the priority protection and management countermeasures of the project area.
5. The specific application of the InVEST model in the supply and demand of ecosystem services, carbon neutrality and other fields and policies
The relationship between the supply and demand of ecosystem services is an important measure to optimize the spatial pattern of the land, and it is an important starting point for the practice of "lucid waters and lush mountains are golden mountains and silver mountains". Optimizing the spatial pattern of land is to improve the supply of ecosystem services, coordinate the contradiction between supply and demand, and achieve a balance between supply and demand on an appropriate scale by optimizing the layout of the ecosystem. In addition, an important prerequisite for the transformation of green mountains and green mountains into golden mountains and silver mountains is to understand the suppliers (supply areas) and consumers (consumption areas) of green mountains and green mountains and their relationship. Revealing the supply-demand coupling characteristics of ecosystem services is an important breakthrough in the practice of "lucid waters and lush mountains are golden mountains and silver mountains". In particular, the "carbon neutral" goal that needs to be solved urgently requires the correct quantification and spatialization of the supply and demand of ecosystem carbon sequestration services.
