The regional distribution of climate is uneven, the small terrain climate is complex, the vertical variation is large, the mountain inversion effect is obvious, and it has the characteristics of mountain forest microclimate. The micro distribution of soil humus and soil layer thickness is obvious, and the soil texture is mostly loam or sandy loam. The area with a nitrogen content greater than 1% accounts for 83%.
