| 摘 要： | 综合运用最近邻分析、Ripley"s K函数、Voronoi图、景观格局指数和缓冲区分析等方法,分析了浙江省桐乡市2013到2018年农村居民点的时空分布及演化特征,还进一步探索了水系、交通和城镇这些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,但乡镇间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。农村居民点分布与河流、道路和城镇距离呈负相关,但河流对农居点的影响逐步降低,道路和城镇对农居点的影响逐步提高,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。

| Abstract: | In this paper, used the nearest neighbor analysis, Ripley"s K function, Voronoi diagram, landscape pattern index, buffer analysis were used, with the aim of analyzing the spatial-temporal distribution and evolution characteristics of rural settlements in Tongxiang City, Zhejiang Province from 2013 to 2018, and exploring the influence of hydrological factors, traffic factors and urban factors on the distribution of rural settlements. Results indicated that the rural residential areas in Tongxiang City show significant agglomeration distribution in both temporal and spatial dimensions, and the degree of agglomeration increases with the increase of years and spatial scales. Although the rural residential areas of each township are clustered, the total area and patch number of rural residential areas vary greatly among towns, and the number, density and fragmentation degree of patches decrease with the years. These changes are related to the positive promotion of comprehensive rural land consolidation and new rural community construction in Tongxiang in recent years. It was also shown that the distribution of rural residential areas is negatively correlated with the distance between rivers, roads and towns, but the impact of rivers on rural settlements is gradually reduced, and the impact of roads and towns on rural settlements is gradually increased. These changes are related to the transfer of freight channels from water transportation to land transportation and the improvement of urban living standards. |
