Spatial-Temporal Characteristics of Green Development Level in River Basin

Abstract

The Tuojiang Basin accounts for 30.8% of Sichuan Province's GDP, but the total water resources account for only 3.5%, resulting in increasing problems of water shortage, environmental deterioration and pollution, which further affects green development in the Basin. The objective of this paper is to investigate the green development of the Basin, expose deficiencies and ultimately unravel the path toward green development in the river basin of China. This paper was based on a green development measurement system under Economy-Nature-Resource-Society-Pollution perspectives and used Crtic method to calculate the weights of system indicators. Then Gray Correlation-Topsis evaluation model was used to measure green development level from 2009 to 2020. Finally, spatial evolution of green development in Tuojiang Basin was analyzed through Moran Index. The results showed that economy and pollution are the important factors of green development. And overall green development level was showing a trend of decreasing first then rising, which reached the lowest in 2014 and highest in 2019. Moreover, all cities in Tuojiang Basin except Ziyang reached a high level of green development in 2020. This paper added various pressure indicators produced by environmental pollution to the index system and enriched the evaluation index system for green development.
