| 摘 要： | 西北内陆盆地冻结期和冻融期几乎占全年时间的1/2,该时期土壤水分运移特点与非冻结期存在较大差异.本文根据北疆昌吉平原区土壤水分运移观测试验,分析了冻结期和冻融期土壤水势分布和土壤含水量变化规律及其与潜水的转化关系,并阐述了冻融水的生态环境意义.

| Abstract: | The duration of freezing and thawing period almost accounts for a half year in the inland basin of northwestern China,in which the characteristics of soil moisture transfer is greatly differential from that of non-freezing period.Based on the observatory experiment on soil moisture transfer in inland plains,the distribution of soil moisture potential and the regularity of soil moisture ratio variation as well as its converting to groundwater during freezing and thawing period are analyzed.The significance of thawed water in eco-environment is also expounded. |

| Keywords: | soil moisture potential soil moisture ratio freezing period thawing period inland basin northwestern China |
