摘要: 采用实地调查和环刀法,研究了王朗自然保护区7种典型生态系统(糙野青茅草地、柳树灌丛、白桦林、混交林、冷杉林、云杉林和方枝柏林)的土壤持水能力,并以此为基础评价了王朗自然保护区的土壤水源涵养能力。结果表明:同一生态系统土壤容重随深度极显著上升而持水能力随深度极显著下降,生态系统系统类型对土壤容重和持水能力有极显著影响,以混交林土壤平均容重最小和持水效果最好;王朗自然保护区土壤的最大持水能力为90 870 361 t,主要贡献都是草地生态系统和混交林。生态系统对区域土壤持水的贡献取决于其面积的大小及其本身的持水能力。基于土壤持水能力的生态系统定向管理中,应加强混交林的建设,在构建的过程中还应注意群落的结构及减少人为干扰。

Abstract: In this paper,studies were made of the soil water-holding capacity of 7 typical ecosystems,which were grass land (dominated by Deyeuxia scabrescens),shrub (dominated by Salix paraqplesia),broadleaf forest (dominated by Betula platyphylla),mixed forest (dominated by Betula spp.and Abies faxoniana),fir forest (dominated by Abies faxoniana),spruce forest (dominated by Picea purpurea) and cypress forest (dominated by Sabina saltuaria) in Wanglang National Nature Reserve (WNNR)in the subalpine of western Sichuan by field survey and ring shear testing,and the assessment were conducted on the regional soil water-holding capacity in Wanglang National Nature Reserve (WNNR).The results indicated that in the studied 7 ecosystems,the soil bulk density increased with the increasing of the depth while the soil water-holding capacity decreased with the increasing of the depth significantly.Ecosystems largely affected the soil bulk density and soil water-holding capacity,and the soil of mixed forest had the smallest bulk density and the largest water-holding capacity.The soil of WNNR could hold 90 870 361 t in all of the studied 7 ecosystems,which were contributed by grass land and mixed forest.Therefore,the contribution to regional soil water-holding depended on the size of a given ecosystem and its water-holding capacity.It was also indicated that ecosystem management for increasing the water-holding capacity should be strengthened to establish the mixed forest,and much attention should be paid to the ecosystem structure and removing human disturbance.
