摘要:
修正的土壤风蚀方程(revised wind erosion equation,RWEQ)被广泛应用于土壤风蚀预报,风因子是该模型的重要参数。RWEQ将风蚀力定义为风因子(wind factor,Wf),RWEQ最初要求使用逐小时风速数据计算Wf。基于中国河北省康保县、拉伯克市两地长时间逐小时风速数据计算了月均、年均Wf(Wf24),并对比了由当地标准时间(local standard time,简称LT)1日4风速(02:00、08:00、14:00、20:00)计算的Wf(Wf4)。结果表明,对于康保县,Wf24Wf4符合得很好(年均Wf24Wf4误差为-2.60%),1日4风速能够用于计算土壤风蚀量;对于拉伯克市,Wf24Wf4之间的误差相对较大(年均Wf24Wf4误差为11.16%),1日4风速可用于评估不同农田管理措施的防风蚀效果;1日4风速的其他组合、1日3风速以及1日2风速等风速组合类型亦可以用于RWEQ模型。可以看出,站点风速的日变化特点是选取风速数据组合的重要影响因素。
