摘要
文中分析了林内透过降水量、林冠截留量、树干径流量及枯枝落叶层截留量，得出林内透过降水量（Ｐｉ）、树干径流量（Ｓ）与林外降水量（Ｐ）呈直线正比关系。即Ｐｉ＝－１．１９９十０．８２９ＰＳ＝－０．１５７９＋０．０４７３Ｐ；林冠截留量（Ｉ）与林外降水量（Ｐ）呈幂函数关系，即Ｉ＝０．７５３９Ｐ０．６１０５；给出了林分密度（ρ）影响林内透过降水量的关系式Ｐｉ＝３．９４５４十０．８２１７Ｐ－０．
The throughfall of precipitation under canopy,interception in canopy,stemflow and interception in litter were analysized in Artifical Chinese pine.in this paper,they turned out that the through fall of precipitation(Pi),stemflow(S)and field precipitation(P)were separately in linear positive c6rrelation,Pi=-1.199+ 0.829PS=-0.1579 + 0.0473P;The interception in canopy(I)and field precipitation(P)were in power function correlation,I=0.7539P0.6105.The correlation among the density of the stands(ρ),the field precipitation (P)and the throughfall of precipitation(Pi)was given, Pi= 3.9454+ 0.8217P-0.0022ρ.
