【摘要】 作为土壤水资源补给的主要途径,入渗决定着土壤对降水和灌溉的有效蓄存程度,影响作物生长和产量。在综述土壤入渗基本理论、测定方法、模拟方程和影响因素分析等方面研究进展的基础上,重点分析了现存问题和未来发展方向。传统土壤入渗研究侧重于单点监测,还需充分考虑环境变化的影响,以定量分析土壤入渗的时空变异规律;监测手段受到尺度限制;基本方程以土体单元单一入渗过程为主,需进一步考虑SPAC系统的协同作用。因此,亟需融合单点监测、遥感反演和数值模拟优势,加强气候变化和人为干扰下土壤入渗时空动态变化特征的研究。更多还原

【Abstract】 As a major way to replenish soil water resources,infiltration determines the effective storage of soil for precipitation and irrigation,and affects crop growth and yield. On the basis of reviewing the research progress of basic theory,measurement methods,basic equations and influencing factors of soil infiltration,this paper focuses on the existing problems and future development directions. Traditional soil infiltration research focuses on single-point monitoring,which is necessary to fully consider the effects of environmental changes to quantitatively analyze the temporal and spatial variability of soil infiltration. Monitoring methods are limited by scale. The basic equation is dominated by the single infiltration process of the soil unit,and the synergy of the SPAC system needs to be considered further. Therefore,it is urgent to combine the advantages of single-point monitoring,remote sensing monitoring and numerical simulation. The research on temporal and spatial dynamic characteristics of soil infiltration under climate change and human disturbance is strengthened.更多还原
