摘　　要：目的对黄土丘陵沟壑区的甘谷县农村居民点景观格局与空间分布特征进行分析,为农村居民点整理和集约节约利用土地提供研究基础。方法运用GIS空间数据分析技术与景观生态学方法,研究甘谷县农村居民点景观格局与空间分布特征,并分析了农村居民点分布与自然环境、生产环境、社会经济环境因素的关系。结果甘谷县农村居民点空间分布的密度大小、规模、形状特征区域差异明显;农村居民点分布格局受坡度、高程、坡向、农用地以及河流和交通道路等自然环境、生产环境和社会经济环境的综合影响;农村居民点在总体上呈现出轻度集聚分布的态势。结论 GIS以及景观指数分析方法的结合能较好地揭示农村居民点分布及其与各种环境因素的关系,是探讨农村居民点空间分布格局形成机制的有效方法。Aim To analyze the rural residential landscape patterns and spatial distribution characteristics in loess hilly and gully region,Gangu County,to provide preliminary research for the rural residential area consolidation and intensive use of land.Methods By using the GIS spatial data analysis techniques and methods of landscape ecology,the rural residential landscape patterns and spatial distribution characteristics in Gangu County were studied,and the interactional relationship between the distribution changes of rural residential land and three environmental elements including natural environment,product environment and social-economic environment was analyzed.Results Studies have shown that the regional differences in density,size and shape features of rural residential areas of Gangu County are significant.Distribution pattern of rural residential areas are affected by slope,elevation,aspect,agricultural land,as well as rivers and roads.Rural residential areas in general,show the trend of the distribution of mild concentration.Conclusion It was pointed out that GIS and landscape indices analysis method is an effective way to explore the spatial pattern of rural residential areas,it lies in its ability to better reveal the distribution of rural residential areas and their relationship with a variety of environmental factors.
