| 中文摘要: |
| 从森林生态系统林冠截留降雨、林下植被及枯落物持水、土壤蓄水以及不同林地土壤的抗侵蚀性等四个方面对黔东南5种森林类型涵养水源功能进行了定量研究遥结果表明：黔东南5种主要森林类型截留率介于9.98%~28.46%，以马尾松纯林和针阔混交林截留效果最好。林下灌木层的持水能力表现为针阔混交林跃马尾松纯林跃落叶阔叶林跃杉木纯林跃常绿阔叶林。草本层持水能力表现为马尾松纯林＞常绿阔叶林＞杉木纯林＞针阔混交林＞落叶阔叶林。枯落物层持水能力大小分别为针阔混交林马尾松纯林＞落叶阔叶林＞常绿阔叶林跃杉木纯林。5种森林类型中落叶阔叶林表层土壤容重最小、仅为0.84g/cm3，对土壤改善最为明显，表层土静态总蓄水量也相对较大。针阔混交林在各个层次的土壤稳渗速度均为最大，因此动态蓄水方面强于其他森林类型袁表层土方面马尾松林次之尧其后分别是常绿阔叶林和杉木纯林袁而落叶阔叶林的表层土壤稳渗速度最小,其土壤抗侵蚀性优于黔东南其它森林类型遥 |

| The main forest types in southeast of Guizhou Province were selected to test their water conservation capacity.The results showed that the average interception rate of different forest types varied f rom 9.98 % to 28.46 %.The best forest type for the effect of canopy interception were Pinus massoniana plantation and broad-leaved mixed forest.The water retention characteristics in shrubs layer from the maximum to minimum was: broad -leaved mixed forest, Pinus massoniana plantation, deciduous broad -leaved forest,Cunninghamia lanceolata plantation, evergreen broad-leaved forest.while herbaceous layer in shrubs layer from the maximum to minimum was:Pinus massoniana plantation, evergreen broad -leaved forest, Cunninghamia lanceolata plantation, broad -leaved mixed forest,deciduous broad -leaved forest. and the water retention characteristics in litter layer:broad -leaved mixed forest 跃Pinus massoniana plantation跃deciduous broad-leaved forest跃Cunninghamia lanceolata plantation跃evergreen broad-leaved forest. The soil bulk density of surface soil in deciduous broad-leaved forest was least (0.84g/cm3),and the Effect of soil bulk density for the Soil improvement in deciduous broad-leaved forest was obvious, surface soil static water storage capacity was the most large in main forest types in southeast of Guizhou Province.The ability of soil infiltration and dynamics of Soil water storage in broad-leaved mixed forest was much matter than other forest types in southeast of Guizhou Province. |
