| 摘 要： | 通过对西乌珠穆沁旗境内不同类型伏沙地的土壤剖面特征和土壤粒径的分析认为:伏沙地土壤具有两层结构,其平均粒径大于地带性土壤.腐殖质层从上至下的粒径变化是先减小后增大.由松散的沙物质组成的母质层能够提供充足的水分,促进了矿物质的循环,使伏沙地的养分输出加快,不利于积累.良好的通气状况便有机物质矿化速度加快,不利于腐殖质的积累.

| Abstract: | The soil section and soil size of different type sinking sandy land were analyzed. It concluded that the soil of sinking sandy land has two level structures, and its average size was bigger than that of regional soil. The sizes of humus soil from top to down changed conversely, decreasing first and then increasing. The parent soil level which contained loose materials could offer enough water, improving the circulation of minerals and speeding up the output of nutrients of sinking sandy land, but having negative impact on accumulation. The good ventilation conditions speeded up the mineralization of organic matter, but being unfavorable to accumulation of humus. |
