Abstract	In this paper, the spatial variation of winter wheat growth and soil nutrient were studied as the objects. Winter wheat growth spatial distribution is not homogeneity, and the Vari-700 index is the best vegetation index to represent winter wheat spatial distribution in heading stage. Winter wheat growth spatial heterogeneity is mainly affected by altitude and soil nitrate nitrogen content in the returning-green stage. Winter wheat grows well in high soil nitrogen content area, grows poor in low soil nitrogen content region. Crop growth is good in high terrain region, bad in low terrain. In addition, the growth of some crop is poor in high soil nitrogen content region because of the low terrain.
