摘要

对长江三角洲森林生态定位站北亚热带次生毛竹林(Phyllostachys edulis)林冠水文作用进行了观测研究。结果表明:(1)毛竹林林冠截留量、透流量、树干茎流量变化范围分别为0.21-4.55mm

0-105.88mm

0-2.8mm;截留率、透流率、树干茎流率变化范围分别为1.3%-100%

0-96.3%

0-11.8%;年截留量、透流量、干流量分别为171.7

864.78

74.3mm;年截留率、透流率、树干茎流率分别为15.5%

77.9%

6.7%。(2)毛竹林林冠截留量(率)、透流量(率)、树干茎流量(率)均与降雨量、降雨强度存在着不同程度的相关性

降雨特征对毛竹林林冠分配降雨的各环节影响最大。(3)不同雨量级、雨强条件下

毛竹林分配降雨效果差异显著。

Abstract

The eco-hydrological effects of north subtropical secondary bamboo forests(Phyllostachys edulis) were observed and studied in the forest ecosystem station of the Yangtze River delta.Results showed that(1) the ranges of canopy interception

stemfall

and throughfall were 0.21-4.55

0-105.88

and 0-2.8mm

respectively;the ranges of canopy interception ratio

stemfall ratio

and throughfall ratio was 1.3%-100%

0-96.3%

and 0-11.8%

respectively;annual canopy interception

annual stemfall

and annual throughfall were 171.7

864.78

and 74.3mm

respectively;annual canopy interception ratio

annual stemfall ratio

and annual throughfall ratio were 15.5%

77.9%

and 6.7%

respectively.(2) The canopy interception(ratio)

stemfall(ratio)

and throughfall(ratio) all had correlation with rainfall amount and rainfall intensity to different degrees and rainfall characteristics had the greatest influence on each link of rainfall redistribution.(3) The differences among rainfall redistribution effects of bamboo forest were significant in the different levels of rainfall amount and rainfall intensity.
