摘要
运用遥感影像提取研究区1998年、2008年、2018年三期农村居民点时空分布数据,利用Fragstats软件、GIS技术和地理探测器等工具研究农村居民点在规模、形状和分布三方面的演变特征,探索区位因素对农村居民点格局的影响方式,分析了经济和社会因素对农村居民点格局演变的作用机制。结果表明:(1)研究区农村居民点用地总体规模和平均规模扩张明显;农村居民点形状变化不明显但不规则性增强;农村居民点分布更加聚集。(2)研究区农村居民点的公路、河流指向性特征显著;无明显铁路指向性特征;城镇对农村居民点的格局影响程度逐渐增大。(3)地理探测器探测结果表明,经济和社会因素对研究区农村居民点空间格局的影响是综合的、多样的和复杂的;农村居民人均纯收入、产业非农化率和城镇化率是对农村居民点规模、形状和分布均产生显著影响的综合性因子,其他因子对农村居民点空间格局的影响具有一定的交叉性和片面性。
Baoding City is located in the middle of Hebei Province,with diverse landforms.We use the tools of landscape analysis software,GIS technology and geographical detector,to describe the evolution characteristics of rural settlements in scale,shape and distribution from 1998 to 2018,discussed the influence of location factors on the layout of rural settlements and the mechanism of economic and social factors on the development and change of rural settlements.First,landscape indexes including total area(TA),largest patch index(LPI),number of patch(NP),percent of landscape(PLAND),mean patch size(AERA_MN),patch size standard deviation(PSSD),mean shape index(SHAPE_MN),mean fractal dimension(FRAC_MN),mean patch perimeter area ratio(PARA_MN),landscape shape index(LSI),patch cohesion index(COHESION)and aggregation index(AI)were selected to calculated,analyze and compare the evolution of rural settlements in plains and non-plain areas.Furthermore,kernel density estimation method was used to show the density distribution of rural settlement patches.Still,overlay and buffer analyses were used to analyze the influence of location factors on the evolution of rural settlement patches.Lastly,P values show the influence of economic and social factors on the evolution of rural settlement patches.The results are drawn as follows.(1)From 1998 to 2018,the overall scale and average size of rural settlement patches in the plain areas are larger than the non-plain areas and the scale difference was increasing;the shape of rural settlement patches in the plain areas was more complex than that in the non-plain areas,but the two areas were still relatively regular in style.The distribution of rural settlement patches in the plain area and the non-plain areas was gradually gathering,and the concentration of the plain areas was higher than that in the non-plain areas.(2)The directional characteristics of highways and rivers in rural settlements were significant;there was no obvious directional characteristics of railways;the influence of urba
