This study evaluates soil hydraulic conductivity (SHC) and water repellency (SWR) in three mixed forest stands in relation to site plant and soil characteristics. The studied forest stands were (i) Pinus nigra Arn. ssp salzmannii and Quercus ilex; (ii) P. nigra Arn. ssp salzmannii and Juniperus Thurifera; (iii) P. nigra Arn. ssp salzmannii, Q. ilex and Juniperus Thurifera. A 100‐ to 120‐year‐old unmanaged P. nigra Arn. ssp salzmannii stand was also chosen as control. The hydrological variables, physico‐chemical properties and surface characteristics of soils were surveyed. Soil water infiltration was higher in Pinus + Juniper mixed forest and Pinus + Quercus + Juniper mixed forests compared to unmanaged Pinus stands. None of the studied forest stands shows a high level of repellency. Only a slight repellency (in unmanaged stands dominated by pines) or moderate repellency (in soils with Pinus and Juniper) were evident, while soils with Pinus and Quercus were not repellent. Differences in SHC among the forest species were driven primarily by the soil texture and associated structure and secondarily by soil organic matter and associated SWR. The latter was mainly due to organic matter content of the soils, but others of the soil physico‐chemical properties and covers analysed were found as influencing parameters to discriminate SWR among mono‐specific and mixed forest stands. While SHC at the studied forest stands could be predicted using organic matter as well as sand and clay contents of the soil, SWR is the result of several hydrological and physico‐chemical parameters.

林分组成和土壤性质对地中海森林疏水性和水力传导率的影响

这项研究评估了三种混交林林分的土壤水力传导率（SHC）和憎水性（SWR）与现场植物和土壤特性的关系。研究的林分是（i）黑松Arn。ssp salzmannii和栎栎; （ii）P。老黑阿恩 ssp salzmannii和刺柏; （iii）P。老黑阿恩 ssp salzmannii，Q。冬青和杜松杜鹃。一个100至120岁的非托管P。老黑阿恩 SSP salzmannii摊位也被选作对照。对土壤的水文变量，理化性质和表面特征进行了调查。与未管理的松林林分相比，松树+杜松混交林和松树+栎+杜松混交林的土壤水分入渗较高。所研究的林分均未显示出高水平的驱虫性。仅表现出轻微的驱避性（在松树为主的非管理林中）或中等的驱避性（在具有松树和杜松的土壤中），而具有松树和栎的土壤不驱蚊。森林物种之间SHC的差异主要由土壤质地和相关结构驱动，其次由土壤有机质和相关SWR驱动。后者主要是由于土壤中的有机质含量引起的，但其他一些土壤理化性质和覆盖率却被认为是在单一和混交林分中区分SWR的影响参数。虽然可以使用有机物以及土壤中的沙子和粘土含量来预测所研究林分的SHC，但SWR是几个水文和理化参数的结果。
