摘要:通过对六盘山北侧不同立地类型华北落叶松、阳坡草地、半阴坡草地、虎榛子灌丛和沙棘灌丛的土壤水文物理性质的调查和比较,结果表明这几种植被类型下的土壤容重、持水性能和渗透性均有较大的差异。土壤持水能力的变化范围为520.34~585.82 mm,初始渗透率变化范围为0.76~9.71 mm,稳定渗透率变化范围为0.50~2.93 mm/min,比较后发现营造的华北落叶松人工林具有很好的增加入渗和涵养水源作用。
The investigation and comparision of soil hydrological and physical properties are carried out in the different types of sites such as Larix principis-rupprechtii, sunny grassland, semi-shady grassland, Ostryopsis davidiana, Hippophae rhamnoides in the north side of Liupan Mountain. The results show that these plots are different among soil bulk density, water holding capacity and the infiltration characteristic. The water holding capacity is between 520.3-585.82 mm; The initial infiltration coefficients and stable infiltration coefficients are between 0.76-9.71 mm and 0.50-2.93 mm/min respectively. After a comparison, it can be concluded that the plantation of Larix principis-rupprechti plays a good role in increasing soil infiltration and water-holding capacity in the studied region.
