ABSTRACT

Economic theory often disregards the impact of its decisions on the biosphere. So we hope to create an ecological service, then the true and comprehensive valuation of the project can be determined and assessed. We use Grey Prediction and Principal Component Analysis (PCA) to create an ecological services valuation model which matches reality and need to change over time. Then we choose the Three Gorges Dam of the Yangtze River in China for research. According to the results, the environmental governance of the Yangtze River started late, so the benefits of certain environmental governance will be very obvious. Therefore, we should pay more attention to ecological protection while strengthening economic construction.
