广东天井山森林群落植物多样性与土壤持水性研究 A preliminary study on floristic diversity and soil water storage capacity of three forest communities at Tianjingshan, Guangdong province

open access: yes, 2002
设样方调查了广东天井山铜桥原生阔叶林、天群次生阔叶林和杉木人工林等3种森林群落的植物多样性、土壤理化性质和土壤持水性能。初步结果显示,天群次生阔叶林的植物种类丰富,多样性指数高,土壤有机质、全氮、全磷、全钾和有效氮含量高,土壤持水性能较好;铜桥原生阔叶林的物种丰富程度稍低于天群次生阔叶林,但土壤速效磷和速效钾则较高,土壤持水性能稍弱;杉木人工林林分组成最简单,物种多样性指数最低 ...

Water holding capacity of moss and litter layers of subalpine coniferous plantations in western sichuan, China

open access: yes, 2002
亚高山针叮林作为长江上游生态屏障的主体,具有重要的水源涵养和水土保持作用,本文作者对川西地区典型的不同恢复阶段的人工云杉林、迹地、次生林和原始林下苔藓与杜枝落叶层贮量和持水性能进行了试验研究,结果表明,人工云杉在生态恢复过程中,苔藓与枯落叶层的贮量和持水性能呈现出波动式递增,表现为30a<40a<60a<50a,50a云杉林达到最大值,苔藓、枯枝落叶层的贮量分别为10.96*10^3kg/hm^2、76.9*10^3kg/hm^2,最大持水量分别为44.77*10^3kg/hm^2、182.5*10 ...
