摘要： 区域土地利用形态与其经济和社会发展阶段相对应,它随着某个区域所处的经济和社会发展阶段的变化而变化。区域土地利用转型,即区域土地利用形态在时序上的变化,它通常与经济和社会发展阶段的转型相对应。论文在划分长江沿线样带土地利用变化的区域类型基础上,结合社会经济统计数据,分析了各区段耕地和建设用地的变化。研究表明,长江沿线样带区域农村建房用地的转型基本上能反映整个样带的区域土地利用转型,且各区段所处的农村建房用地转型阶段非常明显。此外,还发现样带各区段所处的农村建房用地转型阶段与整个样带的社会经济发展水平相吻合。

Abstract: Regional land use morphology is the overall pattern of actual land cover in a region at a given time,comprising the main types of land use.It can be represented either(a)spatially,by a map of a region divided into cropland,pasture land,forestland,urban-industrial land and wasteland,etc.,or(b)non-spatially by the shares of regional territory under each land use type.Furthermore,it can change with the changes of the socio-eco nomic development phase that the region is in.Regional land use transition refers to the changes in regional land use morphology over time,and it usually corresponds to the transition of socioeconomic development phase.Transect of the Yangtze River(TYR),with obvious grads both in the change of physical envi-ronmental factors and in the level of socioeconomic development,was taken as study area in this paper.According to land use changes and pattern,five regional types of land use changes in TYR are classified.Land use changes in several years or decades are mainly driven by socioeconomic factors and restricted by physical factors,and they can be mainly reflected by the changes of cul-tivated land and built-up land,which are tightly interrelated with human productive activities.The changes of farmland and settlements in TYR are examined.Analysis of concerned data showed that the rural housing transition in TYR could reflect its regional land use transition.Regional rural housing transition,that is the development of rural housing of every region,should undergo some stages:the ratio of rural housing to increased settlements decreases gradu-ally,and the end of the transition corresponds to a new equilibrium between rural housing and other construction activities.The study of rural housing transition of every region characterized by land use changes in TYR showed that,every region was in different rural housing transition phase respectively,and they corresponded to their respective socioeconomic development level.

Key words: land use morphology, land use transition, land use change, transect of the Yangtze River
