摘要

为明确浑河上游典型水源涵养林的降雨再分配过程，以浑河上游地区5种典型水源涵养林（红松人工林、落叶松人工林、红松混交林、落叶松混交林、阔叶混交林）为研究对象，应用自记式观测记录仪，分析不同林型林冠层对降水再分配过程（穿透雨、树干茎流、林冠截留）的影响。结果表明：各林型穿透雨量（率）、树干茎流量（率）、林冠截留量均随林外降雨量增加而增大；穿透雨量、树干茎流量、林冠截留量均与林外降雨量呈显著的线性正相关；各林型穿透雨率、树干茎流率与林外降雨量呈显著的对数函数关系；红松混交林、落叶松混交林的树干茎流率（32.12%，15.44%）均高于阔叶混交林与红松、落叶松人工林，红松、落叶松人工林的林冠截留能力（80.66%，77.47%）高于阔叶混交林、针阔混交林。该结果为浑河上游地区水源涵养林的最优空间结构配置与经营管理提供科学依据。

Abstract

In order to explore the redistribution processes of rainfall that were caused by canopy

five typical forest types in the upper reaches of the Hun River

including Korean pine plantation (KP)

larch plantation (LP)

broadleaf-Korean pine mixed forests (BKMF)

broadleaf-larch mixed forests (BLMF) and broadleaved mixed forests (BMF) were studied. Throughfall

stemflow and canopy interception were recorded by automatic data recorder. The results showed that the throughfall

stemflow

and canopy interception in five typical forests increased linearly with an increase of rainfall. The rate of throughfall and stemflow logarithmically increased as rainfall increased. The stemflow in BKMF (32.12%) and BLMF (15.44%) was higher than those in KP

and BMF. The canopy interceptions in KP (80.66%) and LP (77.47%) were higher than those in the other three forest types. This study provides the theoretical basis for the configuration of water conservation forest with the optimal spatial pattern and management strategies in the upper reaches of the Hun River.
