- 摘要:
- 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。
- Abstract:
- Turfgrass were used as test material for actificial rainfall experiments in arid oasis city,and the integrated use of statistical analysis and regression analysis method to study the impact of rainfall time,rainfall intensity and vegetation coverage on the interception of turfgrass.The results showed that under different rainfall intensity,with rainfall time sustained,the amount of interception was rapidly growth,and then tended to be stable;the amount and rainfall time fitting equation was established,and it was found that polynomial equation simulation was the best;interception and vegetation coverage were a proportional relationship,and it decreased with increasing rainfall intensity.By mean of multiple regression analysis,the model was established based on the rainfall time,rainfall intensity and vegetation coverage as the parameters,and the simulation effect was remarkable.
