以试验模拟剖面在不同潜水埋深条件下的负压观测资料为依据 ,用土壤水能量的观点 ,探讨了天山北麓细土平原区包气带水分的运移规律及其与潜水的转化关系。试验研究成果对农业生态环境、水盐运移、三水转化及区域水循环等均有重要意义。同时 ,对其它内陆干旱平原区包气带的研究也具有一定意义和参考价值 According to the negative pressure observation data under different submerged depths of simulated submarine section, with the view of soil water energy, the transport rule of subatmospheric moisture in the fine terra cotta zone along the northern Tianshan Mountains and its relationship with the submersion transformation were discussed . The results of experimental research are of great significance to agro-ecological environment, water and salt transport, transformation of tri-water and regional water cycle. At the same time, the research on gas-bearing zones in other inland arid plains also has certain significance and reference value
