摘　　要：随着人工固沙植被防治土地沙漠化的需要,沙漠(地)的土壤水分深层渗漏动态的研究显得尤为重要。通过详细查阅中国沙漠(地)土壤水分深层渗漏的近年研究成果,综合分析了深层渗漏量的研究方法、时空分布特征及影响因素,指出不足,指明未来研究工作的发展方向与重点领域。认为今后研究工作的重点应通过模拟降雨等试验建立深层渗漏模拟模型;利用水量平衡公式模拟计算土壤蒸发动态等方面进行深入研究与探讨。With the need of artificial sand-fixing vegetation to control land desertification,it is very important to study the dynamics of deep leakage of soil moisture in desert(sandy land).Based on a detailed review of recent research results on deep leakage of soil moisture in China's?deserts(sandy land),the research methods of deep leakage,characteristics of space-time distribution and influencing factors are comprehensively analyzed.The insufficiency is put forward.The development direction and key field of future research work are pointed out.It is considered that the emphasis of recent research work is the establishment of deep leakage simulation model by simulating rainfall.Then,the water balance formula was used to simulate the actual soil evaporation dynamics and other aspects of in-depth study and discussion.
