摘　　要：运用GIS空间分析技术、景观指数法和Voronoi图Cv值相结合的分析方法,研究了胶东山区栖霞市农村居民点的空间均匀性特征,并探讨了农村居民点在地形梯度上的分布特征。结果表明：全市农村居民点分布的Cv值为58.84%,空间分布表现为随机分布;唐家泊镇、松山镇、臧家庄镇和翠屏街道4个乡镇的农村居民点呈集群分布,其他乡镇为随机分布;农村居民点分布的优势区间在1~3地形位,随着地形位的增大农村居民点的优势度降低;农村居民点的面积、斑块数目和平均斑块面积随地形位的增大而减少,平均斑块形状指数和平均斑块分维数随地形位的增大而增大;同时,公路是影响山区农村居民点空间布局的重要因素。研究反映了栖霞市农村居民居住习惯的差异,为农村居民点的整治和规划提供了依据。The research on spatial distribution characteristics of rural settlements is one of the fundamental tasks of rural settlements consolidation.Based on GIS technology,landscape ecology method and Cv value,taking the mountainous area of Qixia City as a case,this paper studied the uniformity of spatial distribution in rural settlements and discussed the influence of terrain niche index on rural residential distribution.The results showed that the Cv of rural settlements in Qixia City was 58.84%,which demonstrated the distribution of rural settlements in Qixia City was random;however,that of four towns′ rural settlements were clustered distribution.With the terrain niche index increasing,the average patch shape index and average patch fractal dimension increased;inversely,the area of rural settlements,the number of patches and the average area of patches decreased.It was also concluded that highroad was the influence factor of rural settlements spatial distribution.It was proposed that the differences of inhabitant custom in rural settlements which provided an academic basis for rural settlements consolidation and planning.
