文章通过判别分析法,尝试构建一套针对不同主体功能定位县通用的指标体系,以反映社会经济发展状况、生态环境保护重要性、国土空间开发支撑条件.通过在广西10个不同主体功能定位县的实践应用,将县城空间划分为城镇空间、农业空间和生态空间,重点开发区、农产品主产区、重点生态功能区的城镇空间分别小于30％、20％和10％,农产品主产区的农业空间和重点生态功能区的生态空间均大于50％.研究成果为全省范围推广县城空间功能区划提供了科学依据.%In this research,discriminatory analysis is used to build up a set of universal index system for different principal function orientation in counties so as to reflect the social and economic development status,the importance of ecological environment protection,and the supporting conditions for the land space development.By practical application in 10 different principal function orientation counties of Guangxi Province,the county space is divided into urban space,agricultural space and ecological space.The urban space of important exploitation zone,main agricultural production zone and ecological function zone is less than 30％,20％ and 10％ respectively,and the agricultural space of main agricultural production zone and the ecological space of key ecological zone is both over 50％,providing a scientific basis for promoting the county spatial function regionalization in the whole province.
