摘要
以江西省2011~2021年11个设区市的统计数据为基础,采用耦合协调度模型、空间自相关模型对江西省土地集约利用与生态环境耦合协调时空发展进行了分析。结果表明:(1)江西省各设区市的土地集约利用和生态环境的协调度与耦合协调度几乎都为上升趋势,仅新余耦合协调度呈下降趋势,景德镇、萍乡、九江、赣州、吉安、宜春、抚州、上饶耦合协调度呈V型,先上升,后下降;(2)江西省土地集约利用和生态环境的耦合协调度总体较高,其耦合协调度的空间特征表现为:北部地区耦合协调程度大于南部与中部地区,并以南昌市为中心呈现聚集状态;(3)江西省2011~2021年土地集约利用和生态环境的耦合协调度的Moran’s I指数在低水平上呈现增长趋势,为低水平的空间正相关,就局部空间而言,主要有高—低聚集、低—低聚集,低—高聚集,三种空间聚集形态,高—低聚集以南昌市为中心,低—低聚集主要分布在赣南,低—高聚集分布在赣北区域,两极分化明显。
Based on the statistical data of 11 district-divided cities in Jiangxi Province from^(2)011 to 2021,this paper uses the coupling coordination degree model and the spatial autocorrelation model to analyze the coupling and coordination spatio-temporal development of intensive land use and ecological environment in Jiangxi Province.The results show that:①The coordination degree and coupling coordination degree of land intensive use and ecological environment in Jiangxi Province are almost all on the rise.Only the coupling coordination degree of Xinyu shows a downward trend.Jingdezhen,Pingxiang,Jiujiang,Ganzhou,Ji'an,Yichun,Fuzhou,and Shangrao showed a V-shaped coupling coordination degree,rising first and then falling;②The coupling and coordination degree of intensive land use and ecological environment in Jiangxi Province is generally high,and the spatial characteristics of the coupling coordination degree are that the degree of coupling coordination in the northern region is greater than that in the southern and central regions.The growth rate in the northern region is greater than that in the southern and central regions.With Nanchang City as the center,it presents a state of aggregation;③The Moran's I index of the coupling coordination degree of land intensive use and ecological environment in Jiangxi Province from^(2)011 to 2021 showed an increasing trend at a low level,which is a low-level spatial positive correlation.In terms of local space,there are mainly three spatial aggregation forms,including high-low aggregation,low-low aggregation and low-high aggregation.High-low aggregation is centered in Nanchang City;low-low aggregation is mainly distributed in southern Jiangxi Province,and low-high aggregation is distributed in northern Jiangxi Province,and the polarization is obvious.
