中文摘要	国土空间优化是促进喀斯特地区可持续发展的重要抓手,也是解决喀斯特地区生态和贫困问题的有效途径。为实现喀斯特地区国土空间的协调发展,研究以西南喀斯特典型区广南县为例,基于城镇-农业-生态功能协调方法和国土空间"双评价"方法的探索,以及冲突空间修正规则的制定,提出了一种国土空间地域功能综合优化分区方法,并结合地理空间建模和统计分析工具,构建了喀斯特地区国土空间地域功能综合优化分区格局。结果表明:1)最适宜级和适宜级占比之和最多的是生态保护适宜性,为61.21%,主要分布于北部和东部,城镇开发适宜性最少,为27.81%,主要分布于中部和南部,农业开发适宜性为49.80%,主要分布于东北部和东部;资源环境承载力以VI级和V级为主,在东北部和东南部承载力等级最高,在南部、西南部和西北部最低;2)在国土空间地域功能优化分区中,与生态功能相关的国土空间类型占据喀斯特地区发展的主导地位,占79.54%,与城镇功能相关的国土空间类型最少,占2.35%;以城镇功能为主导的区域主要分布于中部和东南部,以农业功能为主导的区域主要分布于北部、西部和东部,以生态功能为主导的区域主要分布于北部和南部。3)双评价方法和城镇- 农业-生态功能协调方法的结合能够更精准化和更合理的构建喀斯特地区国土空间格局。不同国土空间地域功能类型的合理布局将为喀斯特地区生态环境质量的提升、石漠化状况的治理以及国土空间的协调发展提供借鉴和参考。
英文摘要	Territorial space is the important carrier of urban construction, agricultural activities, and ecological protection. It is necessary to reasonably promote the coordination, moderation, and sustainable utilization of territorial space. The territorial development of different function types has posed serious conflicts on the regional economy and ecological system, especially in karst areas with fragile ecological environment and high poverty rate. Taking Guangnan County, a typical southwest karst area, as an example, this study aims to realize the coordinated development of territorial space in research regions. A series of geospatial modeling and statistical analysis tools were combined to propose the urban-agricultural-ecological functions coordination method, and the "dual evaluations" method of territorial space in karst areas. According to the environment situation of natural resource and regional planning, amendment rules was also formulated for conflict spaces, while a comprehensive optimization method was proposed for function areas of territorial space. This comprehensive method systematically combined the urban-agricultural-ecological functions coordination and the "dual evaluations", constructed comprehensive optimization patterns of territorial space function areas, and divided different types of territorial space function area in karst areas. The results showed that: 1) In the most suitable level and less, the ecological suitability was the maximum, accounting for 61.21%, which was mainly distributed in the north and east. The suitability of urban development was the minimum, accounting for 27.81%, which was mainly distributed in the middle and south. The suitability proportion of agricultural development was 49.80%, which was mainly distributed in the northeast and east. The carrying capacity of resource and environment was dominated the level VI and V, where the highest level of carry capacity distributed in the northeast and southeast, whereas, the lowest levels of carry capacity in the south, southwest, and northwest. 2) In the optimized function areas of territorial space, seven types of function areas were divided in karst areas. Specifically, the types of function areas related to ecological function dominated in the development of karst areas, accounting for 79.54%. The types of function areas related to urban function were the smallest, accounting only for 2.35%. The areas dominated by urban function were mainly distributed in the middle and southeast, whereas, the areas dominated by agricultural function were mainly distributed in the north, west, and east, as well as the areas dominated by ecological function were mainly distributed in the north and south. 3) Compared with the urban-agricultural-ecological functions coordination method and the "dual evaluations" method, the comprehensive method could more accurately and rationally construct the spatial patterns of territorial space for karst areas. This proposed method can provide an important decision-making support to delimit different areas in karst areas for territorial space planning and ecological restoration. The reasonable layout for different function types of territorial space can provide a sound reference to improve ecological environment, the management of rocky desertification, and the coordinated development of territorial space in karst areas.
