| 摘 要： | 通过对试验小区观测值的分析和研究 ,发现本地区径流量与降雨量呈线性正相关 ,径流量与各瞬时雨强表现出幂函数的关系。径流量与降雨参数 (降雨量、30min最大瞬时雨强和降雨历时 )之间的三元线性回归分析表明 ,除裸地相关性不显著外 ,林地和农地相关性都达到极显著水平 ,可作为估测该区径流量大小的指标。

| Abstract: | Based on the analysis of the observed data from the runoff plot trials, there exists a positive linear correlation between the rainfall rate and the runoff rate, and the power function correlation between the runoff rate and various instantaneous rainfall rate. According to the linear-regression equations, apart from bareland, there also exists a significantly positive correlation in forestland and farmland between rainfall parameters (rainfall rate, maximum rainfall rate during 30min and rain duration) and runoff rate. This linear-regression equations can be used to estimate the runoff rate in Leizhou Peninsular. |
