| 摘 要： | 土地生态经济系统是融自然、社会、经济于一体的复合系统．文章以位于桂东南的横县为研究区，对土地生态经济分区的原则和指标体系进行了探讨，采用GIS技术建立了包括自然生态、土地资源和社会经济等信息的土地生态经济系统的空间数据库，选择其中40项特征指标，运用SPSS软件对研究区的21个农业乡(镇)进行了聚类分析，据此将研究区划分为4类8个土地生态经济分区，在分析各土地生态经济分区的主要特点基础上，提出了土地资源可持续利用和生态建设方向的合理性建议。

| Abstract: | Principles,framework of indices that serves to land eco-economical regionalization were discussed in Hengxian county,an area of hilly-basin in the southeast of Guangxi. The spatial database of a land eco-economical system that includes information of natural ecology,land resources and social economical conditions was established using Geographic Information System (GIS). With the support of SPSS software,forty factors derived from the spatial database were selected to clusteringly analyze for twenty-one villages or towns in the research region. Thus,the research region was divided into four types region,eight land eco-economical zones. The characteristics of every land eco-economical zone are analyzed thoroughly,hence some rational advices about sustainable utilization of land resources and the targets of ecological construction were brought forward. |
