饱和-非饱和带温度广泛用于判断地下水运动。在野外试验获取的实验数据基础上,分析饱和-非饱和的温度变化特征,结果表明:风积沙包气带70cm以上温度呈现昼夜波动特征,70cm以下温度为趋势变化;夜间降水加速了土壤温度的下降,白天降水量较大时对土壤温度影响较大;土壤温度与气温、净辐射呈正相关关系,与气压呈负相关关系;多元线性回归分析表明,气温、净辐射、相对湿度、风速和气压解释了50%以上的饱和非饱和带温度变化。
Saturated - unsaturated zone temperature is widely used to determine the movement of groundwater. The arti- cle is based on field experiments to obtain experimental data and analyzes the saturated - unsaturated temperature variation. The results showed that aeolian sand bags gas with a temperature 70cm above presents the characteristics of diurnal fluctuation in temperatures and the temperature below 70cm trends. The night precipitation accelerated soil temperature decreasing. The precipitation is greater during the day while a greater impact on soil temperature. Soil and air temperature, net radiation showed a positive correlation and negatively correlation with the air pressure. Multiple linear regression analysis showed that the air temperature, net radiation, relative humidity, wind speed and Pressure explain more than 50% of saturation in the un- saturated zone to temperature changes.
