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0.21~4.55 mm,0~105.88 mm,0~2.8 mm;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171.7,864.78,74.3 mm;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。
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 0~2.8 mm,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...
