巴东县不同森林类型林下灌草和凋落物水文效应研究
- Title:
- Studies on the Shrub, Herbage and Litter Hydrological Effect Under Different Forest Type in Badong Area
- Keywords:
- forest type; shrub and herbage; litter; water capacity

- 摘要:
- 对巴东县的不同森林类型林下灌草和凋落物的数量与持水特性进行了调查分析，结果表明：林下灌草生物量最多的是灌木林，其后依次是马尾松林、针叶混交林、针阔混交林、阔叶林和柏木林；灌草层的持水量与其生物量具有密切关系，生物量多的持水量相应也多。林下凋落物层存储量最多的是柏木林，其后依次是针阔混交林、阔叶林、针叶混交林、灌木林和马尾松林；凋落物持水量最多的是阔叶林，其后依次是柏木林、针阔混交林、针叶混交林、灌木林和马尾松林，主要原因是除了受凋落物数量的影响外，还受凋落物持水能力的影响。
- Abstract:
- Through the shrub,herbage and litter amount survey and the water holding characteristic experiment of the litter under different kinds of forest.The result shows that the shrub and herbage amount of different forest type is bush forest,Pinus massoniana Lamb.forest,mixed forest of conifer,mixed forest of conifer and broadleaf,broadleaf forest and Cup ressusf unebris Endl.forest in order.The water holding amount of shrub and herbage have positive relative with their amounts.The litteramount of different forest type is Cupressus funebris Endl.forest,mixed forest of conifer and broadleaf,broadleaf forest,mixed forest of conifer,bush forest and Pinus massoniana Lamb.forest in order.And the water holding amount of litter is broadleaf forest,Cupressus funebris Endl.forest,mixed forest of conifer and broadleaf,mixed forest of conifer,bush forest and Pinus massoniana Lamb.forest in order.And the water holding capacity of the litter form is affected with its amount and component.
