| Abstract: | With Zhouzhi County in Shaanxi Province as the studied area,the establishment and application of maize yield estimation models based on spatial data of soil nutrients was studied. The distribution data of 9 nutrients in the area were obtained through spatial interpolating of points data of soil nutrient in the studied area. The principal component analysis of nutrient content and maize yield were conducted with SPSS software and then the maize yield estimation model was established. |
