Analysis of Tuojiang River Basin’s Green Development Level and Difference Based on PSR Model

Since the the policy that, building a beautiful Sichuan and Tuojiang River green development economic belt has been launched, the Tuojiang River Basin has become one of the most important river basins in Sichuan. Building the Tuojiang River Basin as a pioneer area for green development is of vital significance. This paper selected five cities as the research objects, which are Zigong, Luzhou, Deyang, Neijiang, and Ziyang. Firstly, the paper analyzed the factors affecting the green development of the Tuojiang River Basin, and then combined the PSR model with the “economy-society-resources-nature” indicators to construct a green development indicator system suitable for the Tuojiang River Basin. After that, the entropy weight-grey relational analysis and spatial autocorrelation analysis were used to analyze the green development evaluation system. The results show that average green development levels of Zigong, Luzhou, Deyang, Neijiang and Ziyang are 0.7263, 0.8498, 0.4357, 0.6890 and 0.6856 respectively. Through the spatial analysis, the Moran’s I is 0.104, indicating a significant positive spatial correlation of green development in the Tuojiang River Basin. And the green development level of Ziyang belongs to the high-low agglomeration type. The rest of the areas are not significantly aggregated, and finally suggestions were proposed for improvement.
