Analysis of the Spatial Distribution Character and its Influence Factors of Rural Settlement in Transition-region between Mountain and Hilly
以甘肃天水麦积区为例，利用GIS和统计分析，研究了黄土丘陵与秦岭山地过渡区农村居民点的景观指数、规模等级和空间分布特征，发现高程和坡度对分布影响显著，自然因素为基础而人文社会因素是主要驱动力。
Take Maiji district in TianShui that across the loess hilly region of east Gansu province and west Qinling Mountains as a case,using GIS and statistical analysis,calculating and analyzing the Landscape indices,scale levels and space distribution characteristics of the rural settlement.The research shows that:(a)the area of rural settlements plaques differ greatly,and the plaques number of small and medium size obviously higher than other types;(b)the spatial distribution of rural settlements shows the pattern of thick in the north and sparse in the south,and the directive property of the settlements distribution of rivers and roads is very apparent;(c)elevation and slope have significant influence on the spatial distribution of settlements,the range of elevation about 1000~1500m and slope 5°~15 °is the intensive settlement distribution area,settlements present a significant normal distribution along with the elevation and slope;(d) the forming,development and spatial distribution of rural settlement is influenced by many combined factors.The Natural factor is the foundation of rural settlement formation and development,while the humanities social factor is the main driving factors in the development and spatial evolution of rural settlements.
