中文摘要	为分析干旱区高盐度潜水蒸发与淡潜水蒸发间的关系,提出了干旱区潜水蒸发溶解性总固体(TDS)折算系数(KM)。2012年4月1日2014年3月31日在新疆昌吉地下水均衡试验站开展了不同TDS(30和100 g /L)、不同包气带岩性(细砂和粉质黏土)和不同潜水水位埋深(0.5、1.0、2.0、3.0 m)的蒸渗仪潜水蒸发试验,利用实测的高盐度潜水蒸发数据计算不同条件下的K_M。对潜水蒸发系数和KM进行分析,初步得出了以下结论:高TDS潜水蒸发系数冻结期大于非冻结期,在其他条件一定的情况下,潜水TDS越高,潜水蒸发系数越小;非冻结期高盐度潜水蒸发量小于淡潜水蒸发量,且随着观测时间的延续高盐度潜水蒸发量有减少趋势;冻结期高盐度潜水蒸发量大于淡潜水蒸发量,潜水埋深越大,两者的差值越大,且随着观测时间延续,高盐度潜水蒸发量与淡潜水蒸发量间的差值有变大的趋势;在其他条件一定的情况下,潜水TDS为100 g /L的全年潜水蒸发量小于潜水TDS为30 g /L的全年潜水蒸发量。
英文摘要	In order to analyze the relationship between evaporation of high salinity phreatic water and evaporation of fresh-phreatic water in arid areas,the concept of the conversion coefficient of evaporation TDS of phreatic water in arid areas is introduced. Evaporation tests of the phreatic water are carried out using lysimeters of different TDS (30 and 100 g /L),different vadose lithologies (sand and silty clay) and different water table depths (0.5,1.0,2.0,3.0 m) from April 1,2012 to March 31,2014 at the groundwater balance experimental station of Changji in Xinjiang. We use evaporation data of high-salinity phreatic water to calculate KM under different conditions. The phreatic water evaporation coefficient and KM are analyzed. The preliminary results show that the evaporation coefficient of high TDS phreatic water in the freezing period is greater than that in the unfreezing period. Under certain other conditions,the higher the TDS in the phreatic water,the smaller the evaporation coefficient of the phreatic water. Evaporation of high salinity phreatic water is less than that of fresh water in the unfreezing period. Evaporation of high salinity phreatic water has a decreasing trend with the observation time. Evaporation of high salinity phreatic water is greater than that of fresh water in the freezing period. The difference between them increases with increasing phreatic water table depth and with the increasing observation time. Under certain other conditions,the annual phreatic water evaporation with TDS of 100 g /L is less than that with TDS of 30 g /L.
