吐鲁番乡村聚落空间演变特征研究

Study on the Characteristics of Spatial Evolution of Rural Settlements in Turpan

该文以吐鲁番乡村聚落为研究对象,选取2000年、2010年和2020年吐鲁番土地利用数据和DEM为主要数据源,运用位序-规模法则和GIS空间分析法,研究吐鲁番乡村聚落空间分布特征。结果显示:(1)吐鲁番乡村聚落扩展趋势与乡村位序-规模法则比较符合,聚落日益趋向于中小规模发展;(2)吐鲁番乡村聚落斑块随高程和坡度的变化呈现出偏左正态分布的趋势,密集分布在高程0~452m和坡度0°~3°区域;(3)吐鲁番乡村聚落主要集聚在主要道路与河流两侧。

Taking the rural settlements in Turpan as the research object,this paper selected the land use data and DEM of Turpan in 2000,2010 and 2020 as the main data sources,and used the rank-size rule and GIS spatial analysis method to study the spatial distribution characteristics of the rural settlements in Turpan.The results showed that(1)The expansion trend of rural settlements in Turpan is consistent with the rank-size rule,and the rural settlements tend to develop in a small and medium-sized scale;(2)The patches of rural settlements in Turpan exhibit a leftward normal distribution trend with changes in elevation and slope,which are densely distributed in the elevation of 0~452 m and the slopes of 0°~3°;(3)Rural settlements in Turpan are mainly concentrated on both sides of main roads and rivers.
