With the acceleration of urbanization, the construction land scale of urban and rural areas is constantly expanding, which leads to contradiction and conflict between territorial development and ecological protection becoming more and more serious. Therefore, as an important unit of county (district), and even urban and rural, development, the study on land resource carrying capacity and the rationality of the development can provide some basis for developing the optimal strategies of differential territorial space. Taking Xifeng, Gansu Province, China as the research area, this study constructs the evaluation index system of township construction land carrying capacity from the three dimensions of ecological protection, natural environment, and social economy. It evaluates the suitability of township construction land by the means of a comprehensive scoring method and discusses the carrying capacity and spatial pattern matching of township construction land based on the suitability evaluation results. The results showed that: (1) the spatial difference of suitability of construction land is obvious, which is higher in the city center than in the surrounding areas; (2) the comprehensive carrying capacity of township construction land is 52.62%, and different townships range from 3.78% to 13.15%. It is different between towns; (3) on the whole, the condition of township construction land is well-developed, and the main distribution forms are flaky, banded, and dotted. (4) There is a positive correlation between spatial matching and carrying capacity. The carrying capacity should be considered in regional development to avoid overdevelopment. It can provide a basis for optimizing the territorial spatial layout, strengthening the coordinated development among townships, and improving the comprehensive township carrying capacity in the Loess Plateau hilly and gully region.
随着城市化进程的加速，城乡建设用地规模不断扩大，导致国土开发与生态保护之间的矛盾和冲突日益尖锐。因此，作为县域（区）乃至城乡发展的重要单元，研究土地资源承载能力和发展的合理性，可以为差异化的国土空间发展策略提供一些依据。本研究以中国甘肃省西峰区为研究区，从生态保护、自然环境和社会经济三个维度构建了乡镇建设用地承载能力评价指标体系，采用综合评分法对乡镇建设用地适宜性进行评价，并基于适宜性评价结果探讨了乡镇建设用地的承载能力和空间格局匹配。结果表明：（1）建设用地适宜性的空间差异明显，城区中心高于周边地区；（2）乡镇建设用地综合承载力为 52.62%，不同乡镇在 3.78%~13.15%之间存在差异；（3）整体来看，乡镇建设用地条件较为发达，主要分布形式为片状、带状和点状；（4）空间匹配与承载能力呈正相关。在区域发展中应考虑承载能力，避免过度开发，可以为优化国土空间布局、加强乡镇协调发展、提高黄土高原丘陵沟壑区乡镇综合承载能力提供依据。
