| 摘 要： | 分析了半沙漠流域的水文特征,提出了半沙漠流域分沙漠覆盖区和非沙漠覆盖区的水量平衡关系,在此基础上,提出了确定沙漠覆盖面积的水文分析法,确定了毛乌素沙地周围半沙漠流域沙漠覆盖面积比例,并据实地调查资料作了检验。检验结果表明,提出的半沙漠流域分区水量平衡关系和沙漠覆盖面积确定的水文分析法是合理的,符合实际情况。

| Abstract: | In this paper,the hydr ologic characteristics of semi-desert basin was analyzed,two different water balance equations respectively for desert covered area and non desert-covered area in semi-desert basin were developed,and hence a calculation method for desert-covered area was proposed.The method was tested with field surveyed results of nine semi-desert basins.The calculated and surveyed desert-covered area were very closed. |

| Keywords: | semi-desert basin runoff formation character water balance desert-covered area hydrological method |
