摘    要:采用中子仪、负压计和测温器同步监测沙丘水分、势能和温度场的变化.利用“零通量面”方法(ZFP)首次研究沙丘水分运移特征,并同时引用温度场的热渗透传导、热扩散的不可逆耗散理论解释沙丘水分运移机理.对利用沙丘水分、改造沙漠、治理灾害环境具有实际意义

关 键 词:沙丘  零通量面  运移机理  热渗透传导  热扩散

Authors:Wu Xiuzhen  Zhang Huichang
Abstract:It studies the characteristics of water movement in man made sand dune by the method of zero flux potential for the first time, based on making the observation of changes of water content, potential and temperature simultaneously by using neutron moisture meter, tensiometers and electric temperature gauge. It also explains the mechanism of water movement in the irreversible thermodynamic theory of thermal conduction and diffusion. That is very significant for utilizing water in sand dune, transforming desert and controlling disaster environments.
Keywords:sand dune  zero flux potential  mechanism of movement  thermal conduction  thermal diffusion
