Abstract: Based on the observation data and geographic information data of 69 meteorological stations in Yanqi Basin, the spatial interpolation technology of GIS was used to grid the climatic factors and reclassify them according to the level of regional indicators.The results showed that the suitable planting areas of winter wheat were distributed in the mountainous and gully areas with relatively high terrain around the basin. The more suitable areas are distributed in most of the traditional agricultural areas around Bosten Lake.
