Soil hydraulic properties are important aspects of the bamboo plantation's eco-hydrological processes as they affect the runoff, soil erosion, and water balance. This study assessed the effect of four commercially important sympodial bamboo species viz., Bambusa vulgaris, Bambusa balcooa, Dendrocalamus hamiltonii, and Dendrocalamus strictus on surface soil saturated and near-saturated hydraulic conductivity (NSHC), macropore characteristics, and the factors influencing the soil hydrological processes. The surface soil hydraulic conductivity at 0, -10, and -30 mm pressure heads and macropore characteristics were estimated from measured steady-state infiltration using a tension (hood) infiltrometer. Soil organic carbon, bulk density, aggregate mean weight diameter (MWD), root biomass, and litterfall was correlated with saturated hydraulic conductivity (SHC) to determine these parameters' relationship with the hydraulic properties. D. hamiltonii showed significantly higher SHC, NSHC, and water-conducting macroporosity than the rest of the species. The correlation analysis revealed that root biomass and soil aggregate MWD were the major determinants of soil hydraulic conductivity characteristics. Bulk density, soil organic carbon, and leaf litter were weakly correlated with SHC. Among the species evaluated, D. hamiltonii was found to be a highly promising species for improvement of soil hydro-physical property and, therefore, can be recommended for increasing infiltration, reducing runoff, controlling soil erosion, and improving groundwater recharge.

土壤水力特性是竹林生态水文过程的重要方面，因为它们影响径流、土壤侵蚀和水平衡。本研究评估了四种商业上重要的共生竹种的影响，即Bambusa vulgaris、Bambusa balcooa、Dendrocalamus hamiltonii 和 Dendrocalamus strictus表层土壤饱和和近饱和导水率（NSHC）、大孔隙特征以及影响土壤水文过程的因素。在 0、-10 和 -30 mm 压头和大孔特征下的表层土壤水力传导率是通过使用张力（罩）入渗计测量的稳态入渗来估计的。土壤有机碳、容重、总平均重量直径 (MWD)、根生物量和凋落物与饱和水力传导率 (SHC) 相关，以确定这些参数与水力特性的关系。D. hamiltonii显示出显着高于其他物种的 SHC、NSHC 和导水大孔隙度。相关分析表明，根系生物量和土壤团聚体MWD是土壤导水率特性的主要决定因素。容重、土壤有机碳和凋落物与 SHC 的相关性较弱。在评估的物种中，发现D. hamiltonii是一种非常有希望改善土壤水物理性质的物种，因此可推荐用于增加入渗、减少径流、控制土壤侵蚀和改善地下水补给。
