- 摘要:
- 采用土钻法研究了黄土丘陵沟壑区自然恢复坡面土壤根系的分布特征及土壤养分含量与土壤水分含量对根系分布的影响。结果表明：根系的分布因坡向、侵蚀带、土层深度、植被类型等的不同而异。阳坡根系总生物量高于半阴坡，但差异不显著；沟谷地根系总生物量及≤1mm根系生物量与沟间地各侵蚀带存在显著性差异；随着土层深度的增加，根系生物量减小；不同植被类型及其盖度对根系生物量有很大影响。不同坡向、各侵蚀带、不同土层中各径级根系生物量的总体趋势是≤1mm根系生物量最大，1～2mm次之，2～3mm和>3mm根系生物量较小，且≤1mm根系生物量与2～3mm和>3mm根系生物量间存在显著差异。根系生物量与土壤养分(除全磷)总体为中度正相关，与土壤水分分布不一致。因此，根系分布不仅与植物自身特性有关，还受土壤环境的影响。
- Abstract:
- The root distribution and the influence of soil nutrient and soil moisture on root distribution of vegetation recovery slope on the hilly and gully Loess Plateau were studied. The results showed that the distribution of root varied with slope aspect, erosion belt, soil depth and vegetation types. The total root biomass of south-face slope was higher than that of east-face slope, but there was no significant difference. Significant differences in the total root biomass and ≤1 mm root biomass existed between the gully slope and each erosion belt on the inter-gully slope. The root biomass decreased with the increase of soil depth. Different vegetation types and coverage had great influence on root biomass. Among the different diameter levels, the biomass of root with the diameter less than 1 mm group was the largest, followed by the 1～2 mm group, and the 2～3 mm group and the >3 mm group were smaller, meanwhile there existed significant differences between the root biomass of ≤1 mm group and that of other diameter levels. There was a medium positive correlation between root biomass and soil nutrient(except total phosphorus), and the distribution of root biomass and soil moisture in different soil depth was inconsistent. Therefore, root distribution not only depends on its own characteristics, but also is affected by the soil environmental condition.
