赣南稀土矿区新型城镇化与河流氨氮污染耦合的时空演变及其驱动因素
Spatiotemporal evolution and driving factors of the coupling between new urbanization and river ammonia nitrogen pollution in the rare earth mining area of southern Jiangxi Province
摘要
Abstract
The coupling study of new urbanization and river ammonia nitrogen pollution is of great practical significance for optimizing the quality and speed of urbanization and restoring ecological environment in the rare earth mining area.Taking the rare earth mining area of southern Jiangxi Province as the case study,based on the status of the social and economic environment in the research area,the spatiotemporal evolution characteristics and driving factors of the coupling between new urbanization and river ammonia nitrogen pollution from 2000 to 2020 were revealed using the coupling coordination degree model,spatial auto-correlation and geographic detector methods.The results showed that:(1)In terms of time series,the comprehensive development level and coupling coordination degree of new urbanization in the rare earth mining area of southern Jiangxi Province had steadily improved from 2000 to 2020,showing an S-shaped curve.(2)From the perspective of spatial evolution,the development trend of Dingnan and Quannan County declined slowly in 2010 and 2020 respectively,and generally the coupling coordination degree maintained a stable growth trend.The hot and cold spot of coupling coordination degree remained relatively stable,the coupling coordination degree changed from randomness to regularity,and the agglomeration effect tended to be obvious.(3)Driving factors such as the proportion of urban population,forest coverage rate and increased value of the secondary and tertiary industries had different degrees of influence on the coupling coordination degree of mining areas with certain spatial differentiation.The coupling and coordinated development of the two rare earth mining areas in southern Jiangxi Province was formed by the interaction of various factors and their mutual influence on different types of driving forces.It is necessary to promote the optimization and upgradation of industrial structure in order to realize green development in the rare earth mining area of southern Jiangxi Province.关键词
