摘　　要：资源环境承载能力和国土空间开发适宜性评价是国土空间规划的基础,而县域国土空间规划具有承上启下的作用,县域国土空间双评价如何支撑县域规划一直是重点研究的问题。围绕县级国土空间规划对资源环境要素的选取、国土空间开发适宜性评价、资源环境承载能力评价、国土空间规划优化4个关键问题,以山西省清徐县为研究区,提出基于短板-长板理论的资源环境要素分析和基于地区特色+上下协同的国土空间优化模式,构建适应地区特点的县域双评价框架体系。研究结果表明:清徐县除西部山区、汾河两侧、潇河和水源地一级保护区为生态保护极重要区外,其他地区均为农业生产适宜区和城镇建设适宜区;清徐县农业生产和城镇建设规模主要受水资源约束,该地部分农业灌概区已超出水资源承载规模。研究合理划分清徐县生态、农业、城镇优先发展区,提出县域生态空间、农业空间和城镇空间优化建议,为清徐县等县域国土空间详细规划提供了基础支撑。Resource and environment carrying capacity and suitability evaluation of territorial space development are the basis of territorial space planning.The county-level territorial space planning plays a role of linking the preceding and the following,so“double evaluation”is the key issue of how to support the county-level territorial space layout.The authors in this paper took Qingxu County of Shanxi Province as the research area,and focused on four key issues,including the selection of resource and environment elements,suitability evaluation of territorial spatial development,resource-environment carrying capacity evaluation,and optimization of territorial space planning.The territorial space optimization model was proposed based on the resource and environment elements analysis by short-board and long-board theory and the regional characteristics plus up-down coordination.Besides,the county-level“double evaluation”framework system adapted to regional characteristics was constructed.The results show that Qingxu County is basically a suitable area for agricultural production and urban construction,except for the western mountainous area and both sides of Fenhe River,which are extremely important areas for ecological protection.The scale of agricultural production and urban construction in Qingxu County is mainly restricted by water resources,and some agricaltural irrigation areas in this region have already exceeded their water resources carrying capacity.The priority development areas of Qingxu County s ecological,agricultural and urban development were reasonably divided.Meanwhile,suggestions for the optimization of county-level ecological space,agricultural space and urban space were put forward,which could provide some basic support for the detailed layout of county-level territorial space in Qingxu County.
