| 摘 要： | 针对沙漠包气带的特点，运用中子仪一负压计一地温计联合观测法，对试验场典型地段水位埋深分别为1m，2m，3m的包气带含水量、水分势能和温度场进行了长期野外实地观测，并总结出相应的日变化、季节变化规律，分析了降水、蒸发等气象因素对包气带水分的影响过程，从而得出沙漠包气带水分运移机理及运移规律。为红砂岗矿区水源地水资源评价提供了科学依据。

| Abstract: | According to the characteristic of desert unsaturated zone, through the method of combined observation using neutron moisture meter - densitometer - land temperature meter, water content, moisture potential and temperature field of the unsaturated zones in typical test place have been measured in the open for a long time, where water level depth is one meter, two meters and three meters. This thesis sums up the law of corresponding changes of every day and season, and analyses the climate factors including rain, evaporation etc. how to influence the desert unsaturated water, then it gets the mechanism and the law of moisture transport in the desert unsaturated zone. It provides the scientific guide for the water resources evaluation of headwater in Hongshagang mining area. |
