- 摘要:
- 为了探讨黄土丘陵沟壑区主要群落地上生物量季节变化及其与土壤水分的关系,选择17个样地8个具有代表性的主要群落,通过野外定点跟踪观测,运用相关分析法对生物量和土壤水分的季节变化及二者之间的关系进行了分析.结果表明:(1) 不同植物群落地上生物量具有明显的单峰型季节变异特征,最大值出现在7月或8月份,最小值出现在5月份;(2) 土壤水分在土层垂直方向上具有3个明显的分层,0-100cm土壤水分活跃层、100-300cm土壤水分相对活跃层和300-500cm土壤水分相对稳定层,3个层都有规律性的季节变化特征,其中0-100cm土层土壤水分的季节动态变化最为明显,表现为8月份最大,5月或6月份最小;(3) 地上生物量的季节变化与土壤水分密切相关,0-100cm土层土壤水分对地上生物量季节变化的影响较为明显,随着土层深度的增加,其影响作用逐渐降低;(4) 不同植物群落对土壤水分的消耗作用不同,在植被恢复和重建过程中应因地制宜地选择适宜的物种,以加速整个黄土丘陵沟壑区植被恢复进程.
- Abstract:
- In order to explore the seasonal variation of aboveground biomass of main communities and its relationship with soil moisture in the hill-gully Loess Plateau, 17 sample plots set in 8 representative main plant communities were investigated monthly, and correlation analysis was used to examine the seasonal variation of plant aboveground biomass and soil moisture, and their relationship. The results showed that: (1) aboveground biomass of different plant communities had obvious seasonal variation characteristics with single-peak type, and the maximum appeared in July or August, the minimum appeared in May; (2) soil moisture distribution along the vertical direction of soil profile exhibited three obvious layers, which were active layer of 0-100cm, relatively active layer of 100-300cm and relatively stable layer of 300-500cm. All these three layers had regular seasonal change characteristics. But the variation in the soil layer of 0-100cm was significant, the maximum occurred in August, and the minimum was observed in May or June; (3) seasonal variation of aboveground biomass was closely associated with level of soil moisture. In soil layer of 0-100cm, the effect of soil moisture on the seasonal change in aboveground biomass was more significant. With the increase of soil depth, its effect gradually declined; (4) the different plant community consumption capacity of the soil moisture was various. In the vegetation restoration and reconstruction, we should choose appropriate species according to local conditions in order to speed up the whole hill-gully loess vegetation restoration process.
