摘要
为了研究安徽省村庄群落差异,通过运用Google地图数据和安徽省统计年鉴数据,采用破碎度指数和土地利用率等计算方法,分析了安徽省村庄群落差异。结果表明:地形、地貌对安徽村庄选址和空间形态的总体布局有着决定性的影响;淮北平原地区村庄空间形态多呈团块状,江淮丘陵地区村庄多呈组团型,皖南山区村庄多呈线型;安徽省村庄群落的农业人口密度、破碎度和土地利用率等方面南北差异较大,其中农业人口密度和村庄土地利用率的变化趋势一致,淮北平原区最大,江淮丘陵区次之,皖南山区最小。
In order to study the difference of village community in Anhui, by using Google map data and Anhui statistic yearbook data, ac- cording to the design procedure of degree of size breakage and land use rate, the difference of village community was analyzed. The results showed that the site and spatial form of Anhui village are dependent on the surface features ; the village spatial form of Huaibei Plain is crumb- y, the Jianghuai hilly ground is organizational and the Anhui south region is alphabet of lines ; the north and south of Anhui agricultural popula- tion density, degree of size breakage and land use rate are different, agricultural population density and land use rate variation trends are simi- lar, the biggest is Huaibei Plain,then is Jianghuai hilly ground and the least is Anhui south region.
