摘要
为了探讨不同林龄锐齿栎林分土壤物理性质及水源涵养功能差异,在宝天曼自然保护区开展了相关研究.结果表明,不同林龄土壤各层容重大小顺序均为成熟林>幼龄林>中龄林;对于最大持水量、毛管持水量、最小持水量、总孔隙度、非毛管孔隙度,各层土壤大小顺序均为中龄林>幼龄林>成熟林,不同林龄上述指标随土壤加深均是逐渐减小;不同林龄锐齿栎森林水源涵养功能物质量从大到小分别为:中龄林,17.82×105t.hm-2;幼龄林,15.75×105t.hm-2;成熟林,14.47×105t.hm-2.
In order to investigate difference of soil physical properties and water conservation quercus aliena vat. Acuteserrata of different age,studies were conducted in Baotianman Nature Reserve. The re-suits show： the order of volume weight of different age forest soil from each layer was： mature forest 〉 young forest 〉 middle-aged group forest; for maximum moisture capacity, capillary moisture capacity, minimum water-holding capacity, total porosity, non-capillary prosity, the order was： middle-aged for- est 〉 young forest 〉 mature forest, for the three age groups of forest, indexes mentioned above all de-clined with the deepening of soil; the amount and order of water conservation of quercus aliena var. Acuteserrata forest of different age was middle-aged forest, 17.82×10^5t·hm^-2, young ：forest, 15.75×10^5t·hm^-2, mature forest, 14.47×10^5t·hm^-2.
