摘　　要：基于自定义的土壤颜色量化方法,运用地统计学与GIS技术,将室内布点和实地监测相结合,对果化示范区土壤颜色的空间自相关和空间分布进行了研究。结果表明,果化示范区土壤颜色的空间分布存在正向的全局空间自相关,空间自相关尺度为2 200 m。土壤颜色的空间样点呈现出平行线型的空间分布格局,土壤颜色的空间结构在1～2 200 m区间内为空间集聚,在2 200～2 800 m区间内为空间孤立。示范区棕色土壤广泛分布,黄棕色和黄褐色土壤仅呈小块状的零星分布。According to the customed methods of soil color, by using Geo-statistics and GIS, combining with indoor sampling point distribution and field monitoring of soil color, the spatial autocorrelation and spatial distribution of soil color of typical karst area at Guohua demonstration zone on Baise town in Guangxi were studied. The results showed that the spatial distribution of soil color showed obviously positive global spatial autocorrelation. The spatial autocorrelation distances of soil color was2 200 m. The soil color samples showed the spatial distribution pattern of parallel lines, of that showing two types of spatial structures： the one was spatial agglomeration between 1 m to 2 200 m in spatial distances, the other was spatial isolation between 2 200 m to 2 800 m in spatial distances. The soil in brown was widely distributed, of that in yellowish-brownl, as well as in dark-brown only scattered as small lumps.
