摘　　要：天然坡面径流场,是指布设在地形、土壤、植被等有代表性的天然坡地上,用于观测径流的自然集流区。为研究方便,便于建立运算模型,通常在野外设置观测场进行定量研究,面积因研究尺度不同大小不一,从几十平方米到几千平方米,场地周围应设有围堰,保证集水面积固定,场地内外没有水分交换,同时也保证计算单元的独立性和完整性。传统的径流量通常用量水堰或径流池进行径流过程或总量的监测,而实时在线监测系统进行自动监测和实时记录数据,根据径流形成原理和当地河槽切割河流深度确定三个出流通道,分别监测地表径流、壤中流和地下径流,在计算各分水源的径流量的基础上计算径流总量和径流过程。径流场监测项目主要是降水、蒸发和径流等。Natural slope runoff field is a natural catchment area for observing runoff,which is arranged on representative natural slopes such as topography,soil and vegetation.In order to facilitate research and facilitate the establishment of operational models,observation fields are usually set up in the field for quantitative research.The area varies from tens of square meters to thousands of square meters due to different research scales.Cofferdams should be set around the site to ensure that the catchment area is fixed.There is no water exchange inside and outside the site,and the independence and integrity of the calculation unit are also guaranteed.The traditional runoff is usually monitored by measuring weir or runoff pool for runoff process or total amount,while the real-time online monitoring system is used for automatic monitoring and real-time recording data.According to the principle of runoff formation and the depth of local river channel cutting river,three outlet channels are determined to monitor surface runoff,interflow and underground runoff respectively,and the total runoff and runoff process are calculated on the basis of calculating the runoff of each water source.Runoff field monitoring projects are mainly precipitation,evaporation and runoff.
