摘要:
为探究福建省南平市洪涝灾害受损区不同林型自然恢复过程的土壤微生物群落变化特征,以该区毛竹林、杉木林和次生阔叶林等3种主要林型为研究对象,采用Biolog-ECO板技术研究林地受损、受损自然恢复7年(自然恢复)和未受损3个阶段的土壤微生物群落碳源代谢多样性。结果表明:对不同林型而言,杉木林和次生阔叶林自然恢复样地对6类碳源利用情况优于受损样地,微生物整体活性优于未受损样地,而毛竹林仅对3类碳源利用较好,微生物整体活性低于未受损样地。杉木林和次生阔叶林自然恢复样地微生物多样性指数H、E和D显著优于受损样地(p < 0.05),而毛竹林2样地差异不显著。林型与恢复阶段的交互作用显著影响除多聚物外的其他碳源与H,E,D。对3种林型恢复类型土壤微生物群落具有分异作用的主要碳源是氨基酸类、碳水化合物类和羧酸类。3种林型自然恢复过程中土壤微生物总体活性上升,但次生阔叶林和杉木林微生物群落恢复程度好于毛竹林。(图1表6参31)
Abstract:
In order to explore characteristics of soil microbial community changes during the natural succession process of different forest types in the damaged floods area of 2010 in Nanping City, Fujian Province . Three main forest types, including bamboo forest, Chinese fir forest and secondary broad-leaved forest, were selected as research objects , destroyed plots and undestroyed plots were set up . Biolog-ECO plate technique was used to study the carbon source metabolic diversity of soil microbial communities. The results showed that: (1) The microbial activity of the secondary broad-leaved forest and the Chinese fir forest was natural recovery plots > undestroyed plots, while the natural recovery plots of bamboo forest were only better than destroyed plots . (2) For different recovery stages, the overall utilization capacity of the 6 types of carbon sources in the undestroyed plots were better than that in the damaged plots. For different forest types, the utilization of 6 types of carbon sources in natural recovery plots of Chinese fir and secondary broad-leaved forest were better than that of the destroyed plots. However, in natural recovery plots of bamboo forest, only the use of carboxylic acids, polymers and carbohydrates were better. (3) Different diversity, evenness and dominance index indicated that: the microbial diversity of natural recovery plots of Chinese fir and secondary broad-leaved forests was significantly better than that of the destroyed plots, while the difference between the two plots of bamboo forests was not significant. (4) Two-way analysis of variance showed that: the effects of different forest types on each research factor were less than the different recovery stages. The interaction between the two forest types had extremely significant effects on other carbon sources except for the polymer and diversity index (H) (p < 0.01), and significantly affected the evenness( D) and dominance index(E) (p < 0.05). (5) Amino acids, carboxylic acids and carbohydrates three carbon source types contributed to the differentiation of soil microbial communities from three forest restoration types. This study showed: the overall activity of soil microbes increased during the natural restoration of the three forest types, but the restoration of microbial communities in the secondary broad-leaved forest and Chinese fir forest was better than that in the bamboo forest.? ? ? ? ? ? ? ? ??
