- 摘要:
- 对浙江庙山坞自然保护区天然次生林和人工毛竹林的水文生态特征进行了定位观测研究.结果表明：天然次生林具有较高的林冠截留作用.总林冠截留是人工毛竹林的2.40倍,林冠截留率和产生穿透雨与茎流的最小次降雨量都大于人工毛竹林;天然次生林枯枝落叶层具有较高的截持水能力,其最大蓄水潜力是人工毛竹林的1.88倍;天然次生林的水土保持能力较好,其中人工毛竹林的地表径流是天然次生林的1.92倍,径流泥沙含量高达3.82倍;天然次生林和人工毛竹林降雨分配情况都可以用数学模型模拟,具有较高的相关性与显著性水平.
- Abstract:
- The eco-hydrological characteristics of natural secondary forest and artificial bamboo forest in Miaoshanwu Nature Reserve were observed and studied.The results showed as follows:The effect of canopy interception of natural secondary forest was better,which was 2.40 times as that of artificial bamboo forest.The canopy interception percentage and the minimum rainfall that emerging throughfall and stemflow was higher than that of artificial bamboo forest too.The water-holding capacity of floor litter of natural secondary forest was greater,which was 1.88 times as that of artificial bamboo forest.The effect of soil and water conservation of natural secondary forest was also better.The surface runoff and sediment of artificial bamboo forest were 1.92,3.82 times as that of natural secondary forest.It was very good fit to simulate the laws of precipitation partitioning by Mathematical model,and it had a higher relevance and significance level.
