摘　　要：本文采用最近邻点统计量、Voronoi图及变异系数、景观格局指数和Ripley′s K函数来研究桐乡市农村居民点的空间格局及其演化特征,还进一步探索了水系、道路和城镇3个因素对农村居民点分布的影响。结果表明,桐乡市农村居民点在时间和空间维度上均表现出显著的集聚分布特征,而且集聚程度随着年份和空间尺度的增加而增大。尽管各乡镇的农村居民点均属于集聚分布,但不同乡镇农村居民点的总面积和斑块数量差异较大,而且斑块数量、密度和破碎化程度随年份呈下降趋势,这些变化与近年来积极推进农村土地综合整治和农村新社区建设有关。农村居民点分布与距河流、道路和城镇距离成负相关,但河流对农村居民点分布的影响逐步降低,道路和城镇对农村居民点分布的影响逐步提高,这些变化与货运通道从水运转移到陆运以及城镇生活水平提高有关。This paper used nearest neighbor statistics,Voronoi diagram and coefficient of variation,landscape pattern index and Ripley′s K function to study the spatial pattern and evolution characteristics of rural settlements in Tongxiang City,further explored the influence of three factors of water system,road and town on the distribution of rural settlements.The results showed that the rural settlements in Tongxiang City showed significant agglomeration distribution characteristics in both time and space dimensions,and the agglomeration degree increased with the increase of the year and the spatial scale.Although the rural settlements in each township belonged to the agglomeration distribution,the total area and the number of patches of the rural settlements in different towns were quite different,and the number,density of the patches and fragmentation degree showed a downward trend with the years.These changes were related to the active promotion of comprehensive consolidation of rural land and the construction of new rural communities in recent years.The distribution of rural settlements was negatively correlated with the distance from rivers,roads and towns,but the influence of rivers on the distribution of rural settlements gradually reduced,and the influence of roads and towns on the distribution of rural settlements gradually increased.These changes were associated with a shift of freight lanes from water transport to land transport and improved living standards in cities and towns.
