西南丘陵山区县级土地利用分区研究——以重庆市酉阳县为例

土地利用分区是地域分异规律的体现,在空间区划尤其是土地利用总体规划中处于重要地位.立足于西南丘陵山区,以层次聚类分区方法为主导,以构成自然、社会经济方面的主导因素分区评判为控制,融合地理信息技术研究了酉阳县的土地利用分区问题.结果表明,通过对分区单元的调整优化,将全县划分为中部低山高丘城乡统筹发展区、东部高丘综合农业优化开发区、西南部低山生态旅游开发区、北部中山生态涵养区,明确了区域土地利用的方向和重点,为有效地引导和规范土地利用活动提供了依据.研究认为,在土地利用分区方案编制中,融合地理信息技术应用聚类层次分区方法,能够有效提高分区方案的科学性、针对性和可操作性.

Abstract：

Land-use regionalization is the reflection of the regularity of regional differentiation and plays an important part in spatial zonation, especially in general land use planning. Based on the hilly and moun-tainous regions in southwestern China, using layer cluster method, choosing the natural-socio-economic leading factors as zoning criterions and integrating the geographic information technology, this paper stud-ies the land-use regionalization issues of Youyang county. Through adjustment and optimization of the di-visions, the county is divided into four areas, they are urban and rural development areas with the terrain of high-hills and low-mountains in the central part, comprehensive optimization of agricultural develop-ment areas with the terrain of high-hills in the eastern part, eco-tourism development areas with the terrain of low-mountains in the southwestern part and ecological conservation areas with the terrain of mountains in the north. This makes clear the focus of regional land-use and provides a basis for regulating land-use activities. It is suggested that using GIS technology and layer cluster method can make land-use regional-ization programs more science-based, pertinent and maneuverable.
