摘要： 西昆仑山区位于青藏高原西北隅,高山深谷,原面广阔,地形复杂,气候多样,致使本区土壤垂直带谱类型众多,概分为极干旱、干旱、半干旱和高寒干旱、高寒半干旱5个类型。其中干旱和半干旱型土壤垂直带谱中广布着草原和草甸草原,是塔里木盆地南缘重要的天然牧场。特别是半干旱型中还有云杉林分布,是昆仑山系唯一森林分布区。 本区土壤垂直带谱在边缘山脉与内部山脉之间,低海拔山地与耸立在5000m左右高原面上的高海拔山地之间有明显的差别。

关键词: 垂直带谱, 建谱土壤

Abstract: The West Kunlun Mountains are located in the northwestern part of the Qinghai-Xizang Plateau with complex topographic and climatic conditions, high peaks and deep valleys. All these make the spectra of vertical soil zones very complicated. The spectra can be divided into five categories: super-arid, arid, semiarid, frigid arid, frigid semiarid. In the semiarid spectrum on the Kunlun Muntain range, there is only spruce. In the arid and semiarid spectra in the southern part of the Tarim basin, there are widely distributed meadow grassland and grassland.Significant difference in spectra has been found between the marginal mountains and the interior mountains and between the low hills and the plateau surface above 5,000 meters

Key words: spectrum of vertical soil zones, spectrum-building soill
