以干旱区绿洲城市草坪草为试材,进行人工降雨截留试验,综合运用统计分析和模型回归分析方法,研究了降雨时间、降雨强度和植被覆盖度对草坪草截留的影响。结果表明:不同降雨强度下,随着降雨时间的持续,截留量先是快速增长,随后趋向稳定;建立截留量和降雨时间拟合方程,多项式方程模拟最好;截留量与植被覆盖度呈正相关关系,截留量随降雨强度的增大而减小;通过多元回归分析,建立基于降雨时间、降雨强度和植被覆盖度为参数的草坪草截留量模型,模拟效果显著。 Using artificial turfgrass in oasis urban arid area as tested material, artificial rainfall interception test was carried out. The effects of rainfall time, rainfall intensity and vegetation coverage on turfgrass interception were comprehensively analyzed by means of statistical analysis and model regression analysis. The results showed that under different rainfall intensities, the interception rate firstly increased rapidly and then tended to be stable with the continuous rainfall time. The establishment of the fitted equation of interception and rainfall time, the polynomial equation was the best, and the interception was positively correlated with the vegetation coverage , And the interception amount decreased with the increase of rainfall intensity. Through multivariate regression analysis, the turfgrass interception model based on the rainfall time, rainfall intensity and vegetation coverage was established, and the simulation effect was significant.
