Eco-environmental Effects and Driving Factors of Land Use Transformation in Anhui Province
Studying the ecological effects of the transformation of the"production-living-ecology"space land use is an important way to understand the trend of changes in regional ecological environment quality.From the spatial perspective of the"production-living-ecology",the ecological environment quality index and ecological contribution rate are used to study the impact of the spatial and temporal evolution of land use transformation on the ecological environment in Anhui Province from 2000-2020,and the partial least squares regression model is used to explore the driving factors of the ecological effect during the land use transformation.The study showed that a stable overall land structure of"production-living-ecology"space in Anhui Province tends a gradually expanding living space,an increasing area by 2588.41 square kilometers from 2000 to 2020,and a slightly shrinking production and ecological space by 2517.77 and 73.61 square kilometers,respectively.The trend of ecological environment quality has steadily declined,but the change range was small,with an decrease of the ecological environment quality index from 0.4424 to 0.4396.The distribution of ecological environment quality was step-shaped,and the overall spatial distribution pattern was"high in the southwest and low in the northeast".In the past 20 years,the overall ecological environment quality has decreased slightly,and the obvious ecological quality change index is mainly distributed in the surrounding areas of Hefei City,the urban belt of the Wanjiang River and the banks of the Huai River.Among the driving factors,industrial structure optimization,energy structure adjustment and ecological construction have an obvious promoting effects on ecological environment quality.The increase in population and social consumption as well as the economic development in some areas have made a negative impact on the ecological environment,while the impact of various indicators of foreign trade on the ecological environment is different.It is proposed to focus on the improvement of the environment in key areas and promote the construction of ecological civilization in Anhui Province,give priority to the protection of ecological space and improve the level of ecological security,and give full play to the role of environmental reversal and accelerate the green transformation of production methods,thereby providing reference for Anhui Province in promoting green development.
