| 摘 要： | 国土空间规划是落实主体功能区战略、绘制未来“美丽国土一张蓝图”的重要抓手，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编制的前提和基础.以贵州省黔西南布依族苗族自治州义龙新区为研究对象，围绕生态保护、农业生产、城镇建设功能特征，以定量方法为主、定性方法为辅，依次开展了资源环境要素单项评价、资源环境承载能力集成评价、国土空间开发适宜性评价，并与现状土地利用进行对比，识别其国土空间开发问题和潜力.结果表明:①义龙新区生态保护极重要区面积占比为36.93%，农业生产适宜区面积占比为24.84%，城镇建设适宜区面积占比为25.08%，三者可分别作为重点生态功能区、农产品主产区、城市化发展区.②生态保护极重要区中基本农田面积为23.60 km2、一般农用地面积为15.21 km2，农业生产不适宜区中基本农田面积为72.17 km2、一般农用地面积为27.63 km2，地块功能指向重叠性较大，建议结合城市发展意向，明确不同区域功能指向的侧重.③后备耕地面积为131.87 km2，后备建设用地面积为114.85 km2，与实地核查结果相符.研究显示，构建的喀斯特地区“双评价”方法体系可以很好地应用于区域国土空间规划，实现了格网单元地域功能优化分区.

| Abstract: | Territorial spatial planning is an important action to implement the functional zone strategy and draw a blueprint for a beautiful country in the future. Evaluations of carrying capacity of resources and environment and developmental suitability of land space are the prerequisite and basis of territorial space planning. Taking Yilong District in the southwest of Guizhou Province as a sample, this article focused on the functional characteristics of ecological improvement, agricultural production and urban construction, chosen a quantitative method as the main method and a qualitative method as supporting method to carry out the evaluations, including single-factor evaluation of resources and environments, integrated evaluation of carrying capacity of resources and environments and evaluation of developmental suitability of land space, and compared with the current land use, the constraints and potential of land space development are identified. The results showed that the area of ecologically important zones accounted for 36.93%, the area of suitable zones for agricultural production accounted for 24.84%, and the area of suitable zones for urban construction accounted for 25.08% in Yilong District. They could be used as key ecological functional zones, main producing zones of agricultural products, and urbanization development zones. The basic farmland area in ecologically important zones was 23.60 km2, and the general farmland area was 15.21 km2. The basic farmland area in unsuitable zones for agricultural production was 72.17 km2, and general farmland was 27.63 km2. There was a large overlap in the function directions of the plots. It was recommended to combine the development intentions of the city to clarify the function directions of different regions. The reserve arable land area was 131.87 km2, and the reserve construction land area was 114.85 km2, which was consistent with the field verification results. This research shows that the parallel evaluation system of karst area can be satisfactorily applied to territorial spatial planning to achieve the regional functional optimization zoning of grid cells. |
