nterception capability in an evergreen broad-leaved forest of Ailaoshan,Yunnan Province

    Corresponding author: GONG He-de

Abstract: An experiment was conducted in the evergreen broad-leaved forest (the primitive tree species were Castanopsis wattii and Lithocarpus xylocarpus) of Ailaoshan,Yunnan Province to evaluate its water interception capability and accumulate basic data for forest hydrology. A total of 144 precipitation events from May 2005 to May 2006 were monitored,and a correlation analysis was used to determine the redistribution and interception effects of the tree canopy on precipitation. The total of 1 707.8 mm of precipitation,consisted of throughfall,1 421.8 mm (83.3%);stemflow,15.4 mm (0.9%);and canopy interception,270.6 mm (15.8%). However,throughfall and stemflow could only be recorded when precipitation was over 3.7 mm. A “funnel” shaped canopy structure and duration of rainfall sometimes caused recorded rainfall to be greater than real precipitation;meanwhile a low stemflow of tree with greater diameter at breast height and crowns sometimes resulted from large branch angles and lots of epigrowth. Total throughfall,stemflow,and canopy interception were positively correlated(P<0.01) with precipitation,whereas the canopy interception rate was negatively correlated(P<0.01) with precipitation. Thus,precipitation and forest structure mainly determined interception capability. [Ch,3 fig. 3 tab. 20 ref.]
