Benefits evaluation of ecological restoration projects based on value realization of ecological products.

ABSTRACT

Ecological restoration project is the premise to realize the value of ecological products. The current ecological product value accounting and ecological restoration project benefit evaluation methods are interlinked. The benefit evaluation of ecological restoration projects can not only analyze the completion of ecological restoration projects, but also quantify the impact of externalities on regional development. This study proposes a hypothesis that the benefit evaluation results of ecological restoration projects can affect the realization of urban ecological product value. In order to verify the above hypothesis, this study designed a benefit evaluation framework to evaluate the economic benefits, ecological benefits and project costs of ecological restoration projects. In this study, the benefit evaluation results are divided into three cases to calculate the benefit-cost ratio under different conditions. The three cases are only considering the direct economic benefits (DEB), considering the indirect economic benefits (TEB) and considering the comprehensive benefits (AEB). Taking Jiangyin City of Jiangsu Province as an example, the benefit evaluation of water source protection project in Jiangyin City is carried out. The results show that the benefit-cost ratios in the three cases are 6.68,7.60 and 9.36, respectively. The results show that the benefit-cost ratio is different in different benefit situations. Therefore, when discussing the realization path of ecological product value in ecological restoration areas, it is also necessary to discuss the situation. The evaluation system can provide reference for the benefit evaluation of ecological restoration projects, and also provide data and theoretical support for the realization of regional ecological product value.
