通过对伊犁河流域不同植被带下土壤剖面的采样对比分析,研究了土壤的垂直分布规律,分析了地形、植被对土壤的影响作用。结果表明:伊犁河流域土壤随着海拔高度和植被变化有垂直地带性变化特征。相对来说,南部土壤垂直带谱较完整,自上而下随着海拔高度的下降,土壤垂直带的分布规律是:高山草甸土—亚高山草甸土—灰褐色森林土—山地黑钙土—山地栗钙土;在相同的地理位置,由于地形、植被不同土壤程度发育不同。
Through the comparative analysis of soil samples under different vegetation belts in Yili River Basin, the vertical distribution of soil was studied, and the influence of topography and vegetation on soil was analyzed. The results show that the soil in the Ili River basin has vertical zonal variation along with the altitude and vegetation change. Relatively speaking, the vertical spectrum of soil in the southern part is more complete. From top to bottom, the vertical distribution of soil along the altitude is: alpine meadow soil - subalpine meadow soil - brown forest soil - mountainous black calcium Soil - mountain chestnut soil; in the same geographical location, due to the topography, vegetation, different degrees of soil development.
