摘　　要：在借鉴前人关于土地利用综合分区研究的基础上,采用地域分区和功能分区相结合的两级分类法科学制定土地利用方向,促进区域协调发展。基于云阳县DEM数据,运用ArcGIS的空间分析功能,依据自然条件的地域分布规律,将云阳县划分为4个地貌区,即西部低山岗地区、江北中低山区、江南中低山区、东北中山区。在各个地貌区内部,依据区域社会经济、土地资源和生态环境三方面相关指标,运用因子分析和聚类分析相结合的方法,续分出10个土地利用功能亚区。综合各区域土地利用存在的问题,提出不同区域土地利用布局导向建议,为云阳县土地资源优化配置和社会经济可持续发展提供科学依据。Learning from the previous studies of comprehensive land use regionalization,the direction of land use was made by the means of two-level classification-regional division and functional division to promote the regional harmonious development.Yunyang County can be classified into 4first-level regional zones including hillock zone of western Yunyang,middle and low mountains zone of north Yangtze River,middle and low mountains zone of south Yangtze River,middle-hills zone of northeastern Yunyang.By the means of factor analysis and cluster analysis,sub-divisions in every regional zone were made according to relative indexes of regional social economy,land resource and ecological environment.And then based on the existing land-use problems in each divisional zone,land-use control rules of different zones are put forward.Therefore,the result can provide the scientific basis for optional allocation of land resource and social economic sustainable development of Yunyang County.
