【摘要】 对小蓬竹的水土保持特性进行研究,结果表明:相对于典型的喀斯特灌木群落和草地,小蓬竹群落下土壤的固土、保水、保肥效果更显著。小蓬竹群落林冠层、枯枝落叶层能够截留更多的降水;小蓬竹群落能够有效增加土壤入渗性能;明显增强土壤的抗蚀性和抗冲性;加快土壤的熟化程度,增加土壤肥力,可为喀斯特生态系统的恢复和重建提供理论支持。更多还原

【Abstract】 It was studied that the role of bamboo in water and soil conservation,the result showed:In relation to typical Karst shrub community and grassland,it is found that the capacity of soil-reinforcement,water-restrain,fertilizer-conservation is more evident in Drepanostachyum luodianense(Yi et R.S.Wang)Keng f.community and its canopy,litter layer,humus layer enables to capture more rainfall.The Drepanostachyum luodianense(Yi et R.S.Wang)Keng f.community can also capillary moisture capacity and saturation moisture content,and what’s more,is benefits to strengthen water-storage,water-restrain and water-infiltration,evidently increases soil corrosion resistance and anti-erosion property,and significantly accelerates soil maturation process and increases soil fertility.The study can provide theoretical support for the reconstruction and recoveration of ecosystem of karst with Drepanostachyum luodianense(Yi et R.S.Wang) Keng f.更多还原
