【摘要】 笔者以敦煌莫高窟的水研究为基础,对极干旱区深埋潜水蒸发的研究进展进行了综述与总结。笔者通过对莫高窟的地质、气候的调查与分析得出:极干旱区土壤可能存在潜水来源与潜水蒸发。通过一系列独到的系统实验,对潜水来源、运行机理、蒸发数量、影响因子等进行了监测与分析。结果表明:潜水是极干旱区土壤水分的主要来源,潜水蒸发使古老戈壁土壤富含盐分。潜水蒸发是GSPAC水盐循环的重要环节,也是地球物理循环的重要组成部分,在地球物理、干旱区生态、矿物形成、荒漠化治理、洞窟文物保护等方面具有重要意义。蒸发的数量表明,蒸发潜水具有较高的开发与利用价值,在生态恢复和风沙防治中具有特别的意义。更多还原

【Abstract】 The case of water research at Mogao Grottoes,summarized the progress of the evaporation of deep buried phreatic water in extremely arid zone.Through investigation and analysis the geology and climate of Mogao grottoes,1 thought that the phreatic water may he the source of soil water and the evaporation of phreatic water exactly appeared in extremely arid area.Through a series unique experiments and monitoring to analysis and measure the source of phreatic water,mechanism,the quantity of evaporation,impact factors and etc..The Result shows that the phreatic water is the main source of soil moisture in extremely arid areas,the evaporation of phreatic water makes the ancient gohi soil rich in salt.The evaporation of phreatic water is the important link of GSPAC water and salt cycle,and also is the important part of geophysical cycle.The evaporation of phreatic water has the significance for geophysical,ecological,mineral formation,desertification control,cultural relics conservation of caves.The amount of evaporation shows that the evaporation of phreatic water has high exploitation and utilization value,and with a special significance on sand control and ecological rebuild.更多还原
