摘要
设计了一种基于计算承雨器四周各 1m范围内树冠郁闭度 ,进而通过一次降雨试验可观测到不同郁闭度级林冠截留降雨量的方法 。
A new method to determine crown interception on the basis of calculating crown density where the raingage places within 1 m on all sides to it,which may determine the crown interceptions on different density classes at one time,is designed to solve the difficult problem,the big error in determining crown interception because of the unevenness of canopy density and spaces.
