了解喀斯特地区土壤养分的空间分布特点。选取贵州省关岭县为研究样区，利用克里金插值法分别对选取的有效土壤指标数据进行空间插值，在ArcGIS10.0中得出土壤养分的空间分布变异特点，并与研究样区土地利用现状图对比。研究区土壤各养分指标中土壤缓效钾含量变化最大，空间变化最为剧烈；结合研究区土地利用现状数据对土壤养分指标分别进行空间插值的结果表明，土壤养分包括有机质、全氮、速效磷和缓效钾的空间分布变异特点都与该区域内土地利用类型有关。合理利用土地资源、改进土地利用方式对喀斯特地区土壤保护有积极作用。

This paper aims to study the spatial distribution characteristics of Karst area. Taking Guanling city in Guizhou province as an example, using the Kriging interpolation method for the calibration date to interpolate. Obtain the spatial distribution characteristics of soil nutrient by ArcGIS10.0.Moreover, using the SPSS20.0 to analysis the relativity for soil nutrient indexes. Study on soil nutrient indexes of soil available K content in slow change, spatial change is the severest;combined with the present situation of the study area land use data on soil nutrient indexes are spatial interpolation results showed that soil nutrients, including organic matter, total nitrogen, available phosphorus and available potassium in the spatial variability characteristics are related to the regional land use of type. Utilizing existing resource and improving land patterns have a vital significance for the soil in Karst area.
