中文摘要	基于潜水蒸发的最新国内外研究成果,提出了当前在潜水蒸发研究方面的薄弱之处: 即以往有关潜水蒸发的研究较多集中于其常规影响因素,且大多是对裸土条件下潜水蒸发特性及其计算进行研究,而对种植作物、土表覆膜和特殊土壤等条件下潜水蒸发问题的认识和研究较为不足. 根据中国干旱地区土壤特性和种植模式,分别对有无作物种植、土表覆膜和盐渍土壤等3种条件下的潜水蒸发特性及计算方法进行了较为详细地阐述和评价,并就目前研究中存在的不足和未来亟待深入研究的问题进行了探讨,认为在今后的研究工作中,应把潜水蒸发对作物耗水的补给比例、不同地区适宜潜水埋深和生态地下水位、潜水蒸发昼夜变化特性,以及盐碱地潜水蒸发与土壤积盐的数值模拟等内容作为研究重点.
英文摘要	State-of-the-art studies on groundwater evaporation at home and abroad are surveyed,and the weakest part in them is put forward. It is found that more studies are focused on usual affecting factors, such as atmosphere evaporation intensity,soil texture,groundwater depth and degree of mineralization. Moreover,groundwater evaporation is mostly measured and predicted under bare soil condition, and less investigated for the soils covered with plants and under film mulching and special soil conditions. According to soil feature and planting mode,the groundwater evaporation characteristics and its prediction methods are reviewed in detail under three conditions,such as bare soil covered with plants, plastic-film mulch and saline soil. The drawbacks in present studies and the subjects urgently needed to solve in future are explored. The following contents,namely,contributions of groundwater to crop water consumption,proper and ecological groundwater table for different farmlands,characteristics of day-and night-time groundwater evaporation and numerical simulation of groundwater evaporation and salt accumulation in soil under saline soil condition,should be paid significant attention in forthcoming studies.
