[Objective]This paper aims to rationally manage paddy soil nutrients, provide the scientific basis for rational fertilization in rice production and realize high production and high efficiency of rice production in Guizhou. [Method]The paddy soil nutrient management sub-area is divided by taking accumulated temperature, elevation, topography, soil type and soil nutrient as subarea indexes and using the second-grade subarea method based on GIS technology. [Result] The paddy soil is divided into six first-grade subareas according to the subarea indexes of topography, paddy soil type, effective accumulated temperature and elevation and nine soil nutrient management subareas are divided according to soil nutrient indexes based on the first-grade subarea results in Guizhou. [Conclusion] The complex effective accumulated temperature, topography, soil type and soil nutrient are orderly classified by planning management subarea of paddy soil nutrients in Guizhou.
