Abstract: Using geo-statistics methods,an invstigation was conducted on the spatial variability of soil pH, organic matter, t available N, P, K, and total N, P, K in Shuixi Sightseeing agriculture demonstration zone of Qianxi County (Wuluoba Communities). The results showed that pH was weak variability and the reaining indicators were medium variability, pH, organic matter, t available N, P, Kand total N were lower distributiton in the central region, organic matter were higher distribution in northern and southern regions, available K was high est distribution in eastern region, total N ,K were highest distribution in northern regions.The C0 /(C0 + C) was 31.935% of organic matter, showing a medium spatial correlation, and the reaining indicators indicating showing strong spatial correlations.
