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,分析了安徽省村莊群落差异。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。

AbstractIn order to study the difference of village community in Anhui, by using Google map data and Anhui statistic yearbook data, according 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 crumby, the Jianghuai hilly ground is organizational and the Anhui south region is alphabet of lines; the north and south of Anhui agricultural population density, degree of size breakage and land use rate are different, agricultural population density and land use rate variation trends are similar, the biggest is Huaibei Plain,then is Jianghuai hilly ground and the least is Anhui south region.

Key wordsVillage spatial form; Agricultural population density; Degree of size breakage; Land use rate

村庄是农民聚居的场所,包括建筑与周围的环境。村庄的空间形态包括村庄与自然山水环境的关系、村庄布局形态、建筑道路街巷的形式和尺度以及空间肌理等[1]。随着经济社会的发展和历史的变迁,村庄的空间形态已经发生和正在发生着巨大变化。当前在推进新农村村庄建设的时候,必须根据不同村庄形态类型及布局模式,来探讨符合村庄自身的发展方向与发展模式,以确保新农村建设健康、和谐、可持续发展。

何川等[2]对湖南滨水村镇的空间形态进行举例分析;李欣[3]对苏州村庄的空间形态进行了研究;向兵等[4]将江苏省盐城市农村村庄形态格局分为自然形态布局、集中居住布局、自然与集中居住模式相结合的布局三种类型,并逐一分析其利弊。……
