Land development poses challenges to the sustainable use of resources and environmental health in regions. This study explores the coupling relationship and its spatial-temporal evolution trend between land development intensity and resources environment carrying capacity of 31 provinces in China from 2005 to 2017. The information entropy method, coupling degree model, and coupling coordination degree model are used to calculate the index weight, coupling degree, and coupling coordination degree. The results show that: (1) Three change types of resources environment carrying capacity are presented with land development intensity increasing: first decrease and then increase; first increase and then decrease; and alternating fluctuations. (2) The proportion of construction land, GDP per land, and population density are dominate determinants of land development intensity, while the water resources per capita, energy consumption per unit of GDP, and per capita cultivated land area are that of resources environment carrying capacity. (3) From the perspective of temporal evolution, both coupling and coordination relationship were found to have continuously strengthened. (4) In terms of spatial evolution, the coupling level presented a constantly narrowing inter-regional gap, and the coordination level has changed from initial two-level differentiation to final regional gap narrowing. These findings can provide evidence in support for integrating land development with resources environmental protection to promote regional coordinated development.
土地开发给区域资源可持续利用和环境健康带来挑战。本研究探讨了 2005 年至 2017 年间中国 31 个省份土地开发强度与资源环境承载力之间的耦合关系及其时空演变趋势。利用信息熵法、耦合度模型和耦合协调度模型，计算了各指标权重、耦合度和耦合协调度。结果表明：（1）资源环境承载力随土地开发强度的增加呈现三种变化类型：先降后升、先升后降、交错波动。（2）建设用地、单位土地 GDP 和人口密度是土地开发强度的主要决定因素，而人均水资源、单位 GDP 能源消耗和人均耕地面积是资源环境承载力的主要决定因素。（3）从时间演变来看，耦合和协调关系都在不断加强。（4）从空间演变来看，耦合水平呈现出区域差距不断缩小的趋势，协调水平则由最初的两级分化转变为最终的区域差距缩小。这些发现可以为整合土地开发与资源环境保护，促进区域协调发展提供依据。
