通过对太行山低山片麻岩区８种主要植被类型的土壤渗透性及孔隙状况的调查测定和９种植被类型的坡面径流观测，具体反映出各种植被类型土壤的水土保持性能和涵蓄水分功能。结果表明：松栎乔灌草混杂林、酸枣与荆条灌草丛、中华卷柏和盖度大于７０％的密荒草坡，径流系数小，泥沙冲刷少；土壤渗透性以中华卷柏最大为１．９９ｍｍ／ｍｉｎ；孔隙状况以生长多年的油松林和密草坡最好，非毛管孔隙度分别为２．９％和２．２％；半风化母岩渗速为 ０．９５ｍｍ／ｍｉｎ，非毛管孔隙度为１．２％，具有一定渗透性和贮水功能。
Through the investigation of the soil permeability and the pore condition of 8 main vegetation types in the Taihang mountain low gneiss area and the observation of slope runoff of 9 vegetation types, the soil and water conservation performance and storage of various vegetation types Moisture function. The results showed that: the mixed forest of Quercus acutissima, the jujube and Jingtiao shrubs, the Chinese Selaginella and the close grassland slope with the coverage of more than 70% had small runoff coefficient and less sediment erosion; the soil permeability was about 1 .99mm / min. The best condition for Pinus tabulaeformis and Michelia macclurei is that the porosity is 2.9% and 2.2%, respectively. The infiltration rate of semi-weathered mother rock is 0.95mm / min, The capillary porosity of 1.2%, with a certain permeability and water storage function.
