摘要
乡村聚落物质空间作为乡村地区各项建设与发展的载体,其空间演变特征可以反映乡村聚落发展的规律。选取湘西州花垣县所有的乡村聚落为样本,以时间为轴线,借助ArcGIS10.2、Envi5.2、Fragstats4.2等软件对不同历史年份乡村聚落的空间特征进行分析表达,通过对比总结其演变规律。对于乡村聚落空间演变特征的研究,主要从乡村聚落的空间规模演变特征、空间形态演变特征、空间分布演变特征3个维度,分别选取乡村聚落数量、面积、面积的标准差、平均形状指数、面积加权的平均分形维数、核密度、聚合度指数等指标进行表达。选择2006年、2013年、2020年3个年份作为统计节点,总结花垣县乡村聚落空间规模、空间形态、空间分布的演变特征。
As the carrier of various construction and development in rural areas,the spatial evolution characteristics of rural settlement material space can reflect the law of rural settlement development.Taking all rural settlements in Huayuan county of Xiangxi prefecture as samples and time as the axis,with the help of ArcGIS10.2、Envi5.2、Fragstats4.2 and other software,this paper analyzes and expresses the spatial characteristics of rural settlements in different historical years,and summarizes their evolution law through comparison.The research on the spatial evolution characteristics of rural settlements mainly selected the indicators such as the number of rural settlements,area,standard deviation of area,average shape index,area weighted average fractal dimension,nuclear density and aggregation index from three dimensions,including spatial scale evolution characteristics,spatial form evolution characteristics and spatial distribution evolution characteristics of rural settlements.2006,2013 and 2020 were selected as statistical nodes to summarize the evolution characteristics of spatial scale,spatial form and spatial distribution of rural settlements in Huayuan county.
