- 摘要:
- 为了探讨不同抚育间伐强度下麻栎（Quercus acutissima）林土壤水分渗透规律及影响因素，以桥山林区麻栎天然次生林地土壤为研究对象，对不同间伐强度（对照，10%，20%，30%）近自然经营抚育间伐5年后麻栎林的土壤入渗、土壤基本物理性质和土壤根系进行了研究。结果表明：在0-10 cm土层中土壤渗透性能表现为间伐30% > 间伐20% > 间伐10% > 对照；林地土壤总孔隙度、非毛管孔隙度随着间伐强度增强而增大，间伐达到20%以上显著高于对照，土壤容重则随间伐降低；在10-20 cm土层中，间伐对土壤入渗及土壤基本物理性质并无显著影响；土壤根系结构指标随间伐强度增强而升高；通过相关性分析知，土壤容重、总孔隙度、非毛孔隙度、根长密度、根表面积密度是影响该地区土壤渗透性的关键因素；Philip模型能准确描述该研究区域的土壤水分入渗过程。间伐对土壤表层（0-10 cm）的渗透性具有显著的改善作用，对较深层（10-20 cm）土壤的渗透性并无显著影响。
- Abstract:
- In order to investigate the law and influencing factors of the soil permeability in Quercus acutissima forest under different tending thinning intensities, we took the Q.acutissima natural secondary forests in Qiaoshan forests as the study site. The analyses were made on soil permeability, soil basic physical properties and plant roots of the near natural management tending Q.acutissima forest after 5 years of thinning under different tending thinning intensities (CK, 10%, 20%, 30%). The results showed that the soil permeability ability in 0-10 cm soil layer decreased in the order:thinning rate (20%) > thinning rate (10%) > CK > thinning rate (30%); the total soil porosity and non-capillary porosity of woodland increased with the increase of thinning intensity and the they was significantly higher uneder thinning rate greater than 20% than those of the control, while the soil bulk density decreases with the thinning intensity. Thinning had no significant effect on soil infiltration and soil physical properties in 10-20 cm soil layer. The plant root structure index increased with the increase of thinning intensity. According to the correlation analysis, the soil bulk density, total porosity, non-capillary porosity, root length density and root surface area density are the key factors affecting soil permeability in this area. The Philip model can accurately describe the process of soil water infiltration in the study area. Thinning had a significant improvement on the permeability of soil surface (0-10 cm), but had no significant effect on the permeability of deeper soil (10-20 cm).
