摘　　要：开展区域土地资源承载力评价技术研究,对区域经济社会的可持续发展以及党中央提出的"五位一体"发展思路顺利实现具有重要意义。本文从空间开发利用角度出发,综合考虑对土地开发建设影响显著的因子,运用分步式算法测算适宜建设用地规模及分布,确定土地合理开发强度及分布区域,通过分析现状开发状态与合理开发状态之间的差异评价区域承载状况。并以京津冀地区为例开展案例研究,结果表明:现状开发状态与合理开发状态之间的关系能够有效地反映土地资源承载开发利用的状态;同时以承载建设开发行为为明确承载对象,有显著的政策指向,为精细化、差异化制定空间格局优化调控政策提供了可能。本文从面向国土空间开发利用优化应用出发提出的承载力评价路径,可为中国制定和完善承载力评价相关技术规范提供一些新思路。Carrying out research on evaluation techniques of regional land resources carrying capacity is of great significance for the smooth implementation of national strategic objectives. From the perspective of land development and utilization, this article comprehensively considers the factors that have marked impact on land development and construction. First it estimates the scale and distribution of construction land by distributed algorithm, and then it determines the reasonable intensity of land exploitation and its spatial distribution. Finally, it evaluates the regional carrying status through the analysis of the present development state and reasonable development state. In a case study of the Beijing-Tianjin-Hebei region, the results show that the relationship between the present situation of development and the reasonable development state can effectively reflect the state of land development and utilization with regard to the carrying capacity, Using construction development activities as the evaluation focus has important policy implications because it enables refined and differentiated spatial structure optimization regulation policy making.
