摘　　要：以陇川县农村居民点为研究对象,综合运用GIS分析技术揭示农村居民点空间分布特征与规模空间差异。选取自然环境与社会经济两个方面影响因素,结合景观格局指数分析,研究各因素对农村居民点数量、规模及形状等方面的影响。结果表明:陇川县农村居民点整体分布为聚集模式,空间数量分布呈现由护国乡至城子镇的"带状"和户撒阿昌族乡、勐约镇的"点状"聚集,且农村居民点规模热点与核密度呈现明显负相关的空间特征。影响因素方面,耕地、道路对农村居民点空间分布影响较大,高程、坡度、城镇用地与工矿用地对农村居民点规模差异影响较大,形状特征受坡度影响最大,而交通对其无明显影响。Taking Longchuan County rural residential area as the research object,this paper comprehensively uses GIS analysis technology to reveal the spatial distribution characteristics and spatial differences of scale of rural residential area. Based on the analysis of landscape pattern index,this paper studies the influence of various factors on the number,scale and shape of rural residential areas. The results show that the overall distribution of rural settlements in Longchuan County is an aggregation pattern,and the spatial quantity distribution presents the "belt"from protecting the country to Chengzi Tow n,as w ell as the "point"aggregation of Huzaachang Tow n and M engyue Tow n,and the spatial characteristics of the scale hot spots of rural settlements and nuclear density are obviously negatively correlated. In terms of influencing factors,arable land and road have a greater impact on the spatial distribution of rural residential areas,w hile elevation,slope,urban land and industrial and mining land have a greater impact on the difference in the size of rural residential areas. Shape features are most affected by slope,w hile traffic has no significant impact on them.
