乡村聚落景观格局及其影响因素一直是农村地理学研究的热点问题。本文研究了不同类型的交通工具对乡村聚落景观格局的影响。利用Patch Analyst Version 4.0计算和分析了4种格局指数，利用ArcGIS Version 9.3计算了每个距离带的斑块数量和面积，从而定量地分析和解释了不同类型和等级的交通工具与乡村聚落景观格局的空间关系。结果表明，交通用地是农村居民点景观斑块之间以及景观类型与其他景观类型之间的景观廊道，是物质和信息的传递。国道、、省道、县道与农村居民点景观斑块在空间上呈正相关，国道与农村居民点景观斑块的关联度高于省道S，省道与县道的关联度高于省道S。铁路、高速公路和农村公路在空间上与乡村聚落景观斑块呈负相关，乡村聚落的平均斑块面积随着与交通用地距离的增加而变小，对乡村聚落形成机制和村庄规划布局的研究具有积极意义。
The rural settlement landscape pattern and its influencing factors are always the hot topics of the rural geography.In this paper,we studied different kinds of transports influence on rural settlement landscape pattern.Four pattern indexes were computed and analyzed using Patch Analyst version 4.0,the number of patches and area in each distance belt were calculated using ArcGIS version 9.3.Therefore we quantitatively analyzed and explained the spatial relationships between different kinds and grades of transports and the rural settlement landscape pattern.The farmland is the biggest part of the study district and its spatial connectivity is high,indicting farmland is the landscape matrix.The average fractal dimension、spatial connectivity、edge effects and spatial contiguity of the transport land are higher than other landscape patterns.The result indicated that the transport land is the landscape corridor among the rural settlement landscape patches and between the landscape type and others,which were considered as the transfer of material and information.The State Road、the Provincial Road and the County Road act as positive correlation in space with the rural settlement landscape patches,and the correlation of the State Road is more relevant than the Provincial Road 's,the Provincial Road's is more relevant than the County Road 's,too.The Railway、the Expressway and the Rural Road act as negative correlation in space with the rural settlement landscape patches.The average patch area of the rural settlement would become smaller as the distance from the transport land increases.This paper would be positive to the study of the formation mechanism of rural settlement and the village planning distribution.
