1) runoff starting time
产流历时
1.
Using the two indexes of runoff starting time and steady infiltration rate,the infiltration features of the soil were analyzed.
利用人工模拟降雨对黑龙江西部半干旱区坡耕地不同坡度和不同降雨强度下的土壤水分入渗规律进行了试验研究,采用产流历时和稳定入渗速率二项指标进行分析,发现随着地面坡度的增大,产流历时提前,稳定入渗速率逐渐减小,坡面产流历时与坡度呈对数函数关系,土壤稳渗速率与坡度呈幂函数关系;随着降雨强度的增大,产流历时提前,稳定入渗速率逐渐增大;坡面产流历时与降雨强度呈指数函数关系,土壤稳定入渗速率与降雨强度也呈指数关系。
