Comprehensive Evaluation and Spatial-Temporal Pattern of Green Development in Hunan Province, China

Hunan Province in China is in the initial stage of green development. Human activities and urban construction lead to ecological environmental problems. Based on the physical geography, environmental quality and socio-economic data from 2005 to 2020, this study established a green development evaluation system based on the DPSIR model by analyzing the logical relationship of green development in Hunan Province. In addition, we explored the change characteristics of the green development level, and evaluated the green development in Hunan Province from the time and space dimensions. The results showed that there are significant spatial differences in the green development level of counties in Hunan Province, showing a pattern of "strong in the east, weak in the central and western regions". In addition, from 2005 to 2020, the county's green development index showed agglomeration distribution. The driving forces and pressure systems have a significant role in promoting the green development of the county, while the state and impact systems also have a certain role in promoting the green development of the county. Based on the evolution mechanism of green development in Hunan Province, this paper studied the new green development evaluation system and proposed green development policy recommendations, aiming to provide a scientific basis for the construction of ecological civilization in the region.
