摘　　要：运用Pearson分层聚类分析方法,对重庆市40个区县的土地利用现状数据进行聚类分析,将重庆市分为五大土地利用类型区:工业集中区、农业优势区、外围产业区、农林混合区、林业生态区.结果表明:工业集中区、农业优势区及林业生态区在土地利用结构上存在明显的地域差异;相对于林业生态区,同属典型山区的农林混合区土地开发利用程度明显较高;农业优势区的土地集约利用程度比外围产业区的要高.Based on Pearson hierarchical clustering analysis of the available data of land-use in 40 counties/ districts of Chongqing, five major types of land-use zones are identified： main industrial zone, agriculturedominated zone, peripheral industrial zone, agriculture-forestry mixed zone and forestry ecological zone. Distinct geographical differences exist in the structure of land use among the main industrial zone, the agriculture-dominated zone and the forestry ecological zone. Compared with the forestry ecological zone, the agriculture-forestry mixed zone has a markedly higher degree of land development and utilization, though both zones belong to the typical mountain area. The agriculture-dominated zone has more intensive use of land than the peripheral industrial zone.
