摘    要:随着城市化进程的不断加快,对农村居民点空间布局产生巨大的影响,分析农村居民点空间布局及其时间变化,有利于促进城乡统筹协调发展。文章选取2011年长寿区土地利用变更数据、长寿区1∶50 000 DEM以及该年的社会经济数据作为数据源,用景观生态学、聚落地理学以及图形学的方法,从空间形态、空间分布模式、垂直分布特征方向对长寿区农村居民点空间形态、分布特征进行研究。研究结果表明:长寿区农村居民点空间形态的边界效应不明显性和形状的不规则性突出且在空间分布上表现出明显的规律性和层次性;长寿区农村居民点的分布模式主要呈现集聚—随机模式,其最近邻距指数主要集中于0.85~0.95,在空间上的差异性不明显;在空间垂直分布上,长寿区农村居民点的分布呈突出的规律性,主要集中分布在海拔高度为300~500 m,坡度在6°到15°的区域内。研究成果拟为快速城市化的西南低山丘陵地区农村居民点的规划、管理和发展提供依据。

关 键 词:农村居民点  空间分布  低山丘陵区  景观生态学  聚落地理学  长寿区

Abstract:The development of city has a great impact on the space layout of residents in rural areas. Analysis on the spatial variation and temporal variation in rural areas is propitious to the city and countryside overall plan coordinated development. This paper selects land use change data of 1∶50 000 DEM and the social and economic data of 2011 Changshou District as the data sources. Landscape ecology, settlement geography and graphics methods were used to study the direction distribution space form and characteristics of the rural residents in Changshou District from the characteristics of spatial pattern, spatial distribution pattern, the vertical distribution. The results show that the boundary effect is unobvious and the irregular boundary of shape of Changshou District Rural residential space is obvious, in addition, the spatial distribution regularity and obvious hierarchy are significant. The distribution pattern of rural residents in Changshou district shows the main cluster-random model, the distance to nearest neighbor index mainly ranges from 0.85 to 0.95, and the difference is not obvious in space; in the vertical distribution of spatial distribution of rural residents, Changshou district presents regularly prominent, mainly distributs in the area with altitude of 300~500 m and the slope of 6° to 15°. The research results provided the basis for the planning, management and development of the rural residential area in lower mountains and hilly area of southwest China.
Keywords:rural residential land  spatial distribution  lower mountains and hills  landscape ecology  settlement geography
