如皋市农村居民点空间分布特征分析

摘要

Based on the modified data of land use of Rugao city in 2012, this paper explored the overall characteristics of spa-tial distribution of rural residential land in this city , and further studied the influences of road and river on rural residential land dis-tribution .The findings showed that:the rural residential land in Rugao city belonged to the high-density region , and presented an u-niform distribution pattern;the proportion of rural residential land on the two sides of roads and rivers was 6 times the average pro-portion, and that on the two sides of rivers was even higher;the influencing distance of road on rural residential land distribution was significantly bigger than that of river , and the influence ability of road was 9 times that of river , leading to the differences in rural residential landscape pattern along roads and rivers;as for the distribution of rural residential land along rivers , the arterial traffic was an important influential factor .%以如皋市2012年土地利用现状变更数据为基础，在讨论其农村居民点空间分布总体特征的基础上，进一步研究了公路及河流等因素对农村居民点分布的影响程度。结果表明：如皋市各镇农村居民点属于高密度地区，并呈现均匀分布格局；公路及河流两侧农村居民点比重可达到平均比重的6倍，且沿河流两侧比重更高；但公路对农村居民点用地分布的影响距离要显著高于河流，其影响能力是河流的9倍，并由此导致沿公路和河流两侧的农村居民点景观格局出现差异；对于农村居民点的河流布局，交通干线是重要考虑因素。
