摘　　要：以陕西省商州区为研究区域,从自然、社会经济和生态角度出发,构建农村居民点的综合影响力评价指标体系,分析了农村居民点的影响力及其等级划分.应用加权Voronoi图等空间分析技术,确定各居民点的整理方向,实现全区农村居民点的布局规划.结果表明:各农村居民点综合影响力存在较大差异,将居民点分为高级居民点587个、中级居民点1 052个和低级居民点984个;各等级居民点的空间分异特征明显;农村居民点有集中发展、优先发展、内部整理和拆迁合并4种整理方向,商州区农村居民的整理应坚持"集中发展为主,优先发展为辅,兼顾内部整理和拆迁合并"的策略.Taking Shangzhou district of Shaanxi province as study area,the comprehensive influ-ence evaluation indexes of rural residential areas are established from the natural,social and eco-nomical,ecological aspects,and the influence and grade division of rural residential areas are ana-lyzed.Using the weighted Voronoi diagram technology,the consolidation direction of rural resi-dential areas is determined,and the layout planning of rural residential areas in Shangzhou district is realized.The results indicated that all the villages were classified into three categories,namely 587 high-level villages,1 052 mediate-level villages,984 low-level villages according to grades of rural residential comprehensive influence.The spatial features of different grades of rural residen-tial areas are significantly different.There presented four feasible directions of land consolidation for villages,that is,centralized development,prior development,interior consolidation and di-rection of consolidation and combination.
