| 摘 要： | 为了探究岫岩地区不同类型水源涵养林内土壤储水能力,对该区域红松(Pinus koraiensis)林、落叶松(Larix spp.)林、灌木林、混交林〔红松+白桦(Betula platyphylla)〕、红松采伐迹地等5种不同类型水源涵养林根系分布特征进行了研究,结果表明:5种水源涵养林中,根系主要集中分布在0~40 cm土层中,2 mm以下较细径级的根系占比较大,有较好的涵养水源效果,其中,以灌木林、红松林、红松+白桦混交林涵养水源的效果较好,根系数量相对较多,较细根系分布比例高。

| Abstract: | In order to explore the soil water storage capacity of different water conservation forests in Xiuyan Area,the root distribution characteristics of five water conservation forests in the region,including Pinus koraiensis forest,Larix spp.forest,shrub forest,mixed forest(Pinus koraiensis+Betula platyphylla),and Pinus koraiensis logging area.Result shows that among the five water conservation forests,the roots are mainly distributed in the 0-40 cm soil layer,and the roots of the finer diameter below 2 mm account for a larger proportion of the roots,which have better water conservation effects.Among them,the shrubs,Pinus koraiensis and Pinus koraiensis+Betula platyphylla mixed forest have better water conservation effects,with a relatively large amount of root coefficient,and a higher proportion of finer root systems. |
