1182 | 562 | Ecological Policy Effect Evaluation from the Perspective of Vegetation Restoration “Potential – Realization”: Theoretical Exploration, Model Construction and Application Demonstration

Vegetation restoration is a global issue and research hotspot. Ecological policy plays an important role in achieving vegetation restoration. It is of great significance for optimizing policy design and improving policy efficiency. However, previous research can hardly separate the respective roles of resource endowments and ecological policies in the effects of vegetation restoration, and it is impossible to accurately match ecological policies and their evaluation units, resulting in confusion between ecological policies and vegetation restoration effects and affecting the accuracy of policy evaluation. Therefore, the perspective of vegetation restoration “potential – realization” was proposed to improve the evaluation work. Based on thesis analysis, a new evaluation model was established, to obtain a vegetation restoration potential achievement index that can effectively reflect the ecological policy effect. Then, taking the Loess Plateau as an example, combined with the interpretation of the parameters of the model, the application demonstration of the analysis framework and the new model is carried out. The main conclusions are as follows: (1) Through theoretical deduction, it is demonstrated that the vegetation restoration potential achievement index can effectively shield the influence of resource endowment conditions and better reflect the vegetation restoration effect of ecological policy; (2) The case study further verifies the theoretical derivation; (3) The joint analysis of traditional vegetation coverage index and potential achievement index can provide more useful information for the sustainable restoration of vegetation. In conclusion, this study is expected to provide new theoretical and methodological support for ecological policy evaluation and vegetation restoration planning.
