阿尔泰山南坡主要土壤类型及分布

Main Soil Types and Soil Vertical Distribution in Altay Mountains Area,Xinjiang

通过样地调查与土壤理化分析相结合对阿尔泰山南部山区的土壤特性进行研究,确定该区域主要的土壤形成特征有有机物质积累特征、粘化特征、钙积特征、盐积特征和相应的化学组成及粘土矿物特征;按土壤发生学分类将主要土壤类型划分为9个土类,从高到低,形成较为完整的土壤垂直谱,并比较了东西部差异;该区域具有温带荒漠草原土壤垂直分布的典型特征,在干旱中温带的山地土壤中有代表性。

In order to confirm the soil types in altitudinal belts in the Altay Mountains, the author investigated the climate, plant, and soil resources. Some characteristics of soils in different elevation highlands in the Altay Mountains were studied. The soil has organic matter accumulative characteristics, clayification characteristics, calcic characteristics and salic characteristics in the area. Based on the Chinese Soil genetic classification, the results showed that the spectrum of vertical distribution is nine. The mountains are huge in the area, and the vertical distribution is intact. There are remarkable differences from the east to west. The soll has typical characteristics of vertical distribution along the temperate zone of the desert steppe, it is a representative in desert middle temperate zone mountains soil.
