| 摘 要： | 江苏省丹阳市即将实施统筹城乡发展改革试点项目,如何加快农村居民点土地整理是项目面临的一个难题。该研究以丹阳市2010年土地利用现状调查数据库为基础,采用Ripley’s K函数分析方法,分析了农村居民点空间分布尺度特征,研究了公路、河流、农村道路等交通因素对农村居民点分布的影响程度。结果表明:丹阳市各镇农村居民点在镇级尺度呈现均匀、随机和聚集3种分布模式,在村级尺度呈现聚集和均匀2种分布模式。公路、河流、农村道路等交通线路两侧农村居民点用地比例为平均用地比例的2～3倍。交通线路两侧农村居民点用地比例距离系数的大小与农村居民点的空间分布相关,在更小的尺度范围内,公路、河流和农村道路对农村居民点空间分布影响程度不同。该研究为丹阳市农村居民点土地整理的实施提供重要参考。

| Abstract: | In order to accelerate land consolidation of rural residents, which is about to be implemented in Danyang city Jiangsu province, scale characteristics about the spatial distribution of rural settlements and transportation factor influence on distribution of rural settlements were analyzed by using the GIS spatial analysis method such as the Ripley's K function analysis based on the land survey use database about Danyang City in 2010.The results showed as follows: 1) In the township scale, the spatial pattern of rural settlements presented three kinds of patterns, such as uniformity, randomness, and cluster. However, in the village scale, it presented both the uniformity pattern and the cluster one. 2)The proportion of rural settlements on the both sides of the transportation lines, such as highways and rivers, country roads was 2-3 times of the average proportion of rural settlements. The distant coefficient of rural settlements on both sides of traffic lines was closely related to the distribution of rural settlements. In the smaller scale range, the effects of highways, rivers, and country roads on the spatial distribution of rural settlements were different. This research could provide an important reference for the smooth implement of the land arrangement of rural settlements. |
