森林增雨效应的实例分析

Illustration analysis of forest on precipitation increasing

对安徽省滁州地区和大别山区的44个雨量站资料进行相关分析。结果表明,森林能增加大气降水,森林覆盖率增加1%,丘陵地区年平均降水量增加7.99 mm,山区年平均降水量增加约16.59 mm。森林对局地降水量影响大,对过程降水影响小。

The forest can increase the atmospheric precipitation. The annual mean precipitation will increase 7.99 mm in the hilly area and approximately 16.59 mm in the mountainous area as the forest coverage fraction increases by 1%. The forest greatly affects the local area precipitation, but slightly affects the process precipitation.
