| 摘 要： | 该文根据2004年8月的实测数据，对三峡库区重庆缙云山4种典型林分（马尾松阔叶混交林、常绿阔叶林、楠竹林和常绿阔叶灌丛）森林土壤的持水和入渗特性进行研究.结果表明，4种典型林分森林土壤的非毛管持水量是农地的1.5～2倍；除楠竹林外，各林分土壤的有效蓄水容量为农地的1.1～1.9倍；各林分土壤持水量为:常绿阔叶灌丛（454.1 mm）马尾松阔叶混交林（327.6 mm）常绿阔叶林（292.5 mm）楠竹林（218.9 mm）； 4种典型林分森林土壤稳渗率的顺序为:常绿阔叶灌丛（10.169 mm/min）楠竹林（0.927 mm/min）马尾松阔叶混交林（0.743 mm/min）常绿阔叶林（0.551 mm/min）农地（0.253 mm/min）； 从土壤持水性能和入渗性能来看，常绿阔叶灌丛的水源涵养和理水调洪功能远好于其他林分土壤，而马尾松阔叶混交林优于常绿阔叶林，楠竹林较差.

| Abstract: | In order to evaluate hydrological functions of different vegetation communities in the Three Gorges Region,the results of a study in August 2004 on the water retaining capacity and infiltration property of soil of four typical forest stands(mixed Pinus massoniana-deciduous forests,evergreen broadleaved forests,Phyllostachys pubescens forests and evergreen broadleaved shrub forests) in the Jinyun Mountain of the Three Gorges Region,Chongqing were presented.Study showed that the non-capillary water retaining capacity was 1.5(--)2 times as high as that of arable farmland soil and the effective water storage of the soil was 1.1(--)1.9 times as high,the exception was the soil of P. pubescens forests.For the four forest stands, the water retaining capacities of the soil were ranked as follows: evergreen broadleaf shrub forests(454.1 mm) > mixed P.massoniana-deciduous forests(327.6 mm) > evergreen broadleaf forests(292.5 mm) >P.pubescens forests(218.9 mm).The stable infiltration rates of the soil of four typical forest stands were ranked in the following order: evergreen broadleaf forests(10.169 mm/min) > P.pubescens forests(0.927 mm/min) > mixed P.massoniana-deciduous forests(0.743 mm/min) > evergreen broadleaved forests(0.551 mm/min) > arable farmland(0.253 mm/min).In general,the soil of the evergreen broadleaved shrub forests has the best hydrological function in soil water retention capacity and infiltration property.These characteristics are better in the mixed P.massoniana-deciduous forests than in the evergreen broadleaf forests,while the performance of the P.pubescens forests is worse in both capacities. |
