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OA
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
开展新型城镇化与河流氨氮污染的耦合研究,对稀土矿区优化城镇化质量和速度,修复生态环境状况具有重要现实意义.以赣南稀土矿区作为研究对象,基于研究区社会经济环境现状,综合运用耦合协调度模型、空间自相关及地理探测器方法分析 2000-2020 年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规律及驱动因素.结果表明:(1)时间序列上,2000-2020 年赣南稀土矿区新型城镇化综合发展水平与耦合协调度稳步提升,呈现"S"型曲线变化特征;(2)从空间演变来看,定南县和全南县分别在 2010 年和 2020 年缓慢下降的发展趋势,总体上耦合协调度保持稳定增长态势.耦合协调度的热点区以及冷点区均保持相对稳定,且耦合协调度由随机性向规律化转变,集聚效应趋于明显;(3)城镇人口比重、森林覆盖率、二三产业增加值等驱动因素对矿区耦合协调度产生不同程度的影响,具有一定的空间分异.赣南稀土矿区两者耦合协调的发展是多种因素相互作用、相互影响于不同的类型驱动力所形成,需立足赣南稀土自然资源优势,促进产业结构优化升级,实现矿区绿色发展.
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.
