摘　　要：农村居民点的空间分布及变化特征的研究可为农村居民点空间布局优化及建设用地的合理利用提供参考。以江西省安福县为研究区域,运用GIS空间分析及景观指数分析方法,分析了区域环境综合影响下的农村居民点空间分布及变化特点。结果表明:随着农村社会经济的发展,安福县农村居民点用地面积增加了2 095.12hm2,用地规模扩大明显;空间分布的密集程度不断提高,属于分布较为密集区;农村居民点扩展表现为整体上的分散化和局部的规模集中化;用地的空间形态趋于非紧凑性,用地扩展属于外延类型;农村居民点分布格局受自然和社会经济环境的综合影响,空间扩展逐渐向地势相对平缓、交通更便利、经济发展条件较好的地方集中。安福县农村居民点集约利用潜力较大,今后应正确引导农村居民点的空间分布,促进其空间布局的优化。Study on the characteristics of spatial distribution and changes of rural residential areas can instruct spatial distribution optimization and the rational utilization of rural residential areas. Anfu County was se- lected as a case, intending to discuss the spatial distribution and changes of rural residential areas under the multiple regional environments by using spatial analysis and landscape index methods. The results showed that the scale and density of rural residential areas increased significantly with the development of rural social and economic. The scale of rural residential areas in 2010 was 2 095.12 hm2 larger than it in 1996. Second, it showed the general expansion in the distribution with small scale of centralized residences. Third, the fractal features of rural residential areas tended to non compact. Fourth, the expansion of rural residential areas tended to the areas with flatter terrain, better transportation infrastructure and more developed economic environment. Intensive use and potential of rural residential areas in Anfu County are great. Spatial distribution of rural residential areas should be correctly guided to promote the spatial distribution optimization.
