摘要:
本文以会同地区杉木人工林采伐迹地自然恢复后形成的次生林为研究对象,以杉木人工林和常绿阔叶林作为对照,调查了杉木人工林、次生林和常绿阔叶林的土壤动物群落特征。结果显示:杉木人工林采伐迹地自然恢复20 a后,次生林与常绿阔叶林土壤动物在群落组成上表现了更高的相似性,其中次生林与杉木人工林Jaccard相似性为0.57,杉木人工林与常绿阔叶林相似性为0.58,次生林与常绿阔叶林Jaccard相似性为0.64;杉木人工林采伐迹地自然恢复后,土壤动物群落的多度出现了显著的增加,从杉木人工林的52 916.1 ind/m2,增加到次生林的86 618.7 ind/m2(P = 0.03),接近常绿阔叶林的78298.4 ind/m2(P = 0.75),这些增加主要归因于线虫纲、线蚓科、蜱螨目、弹尾目的增加,分别贡献了增加量的62.84%、26.57%、4.74%、2.26%。但土壤动物群落的多样性变化缓慢,Shannon多样性指数从杉木人工林到次生林增加了25.71%,达到常绿阔叶林的88.88%。通过比较3种森林类型土壤动物多度和多样性,明显可以看出土壤动物的多样性恢复速度要慢于土壤动物的多度恢复。由于次生林的群落组成、多样性和多度特征比杉木人工林更加接近于常绿阔叶林,因此结果支持生态系统不稳定性的增加促进了土壤生物的恢复。
Abstract:
Taking fallow blanks of clear-cutting Chinese fir (Cunninghamia lanceolate (Lamb.) Hook.) plantation (FF) as research object and Chinese fir plantation (FR) and secondary evergreen broad-leaved forest (SF) as the controls, characteristics of Soil faunal community of Chinese fir plantation, fallow blanks of clear-cutting Chinese fir plantation and secondary evergreen broad-leaved forest were investigated in Huitong of Hunan Province. Results showed that the composition of soil faunal community in the fallow blanks of clear-cutting Chinese fir plantation and secondary evergreen broad-leaved forest showed a higher similarity after 20 years being fallowed in Chinese fir plantation, among which the similarity Jaccard coefficient between the fallow blanks of clear-cutting Chinese fir plantation and secondary evergreen broad-leaved forest was 0.64, that Jaccard coefficient between the Chinese fir plantation and secondary evergreen broad-leaved forest was 0.58, and that Jaccard coefficient between the fallow blanks of clear-cutting Chinese fir plantations and secondary evergreen broad-leaved forest was 0.57. After fallow in clear-cutting forestland of Chinese fir plantation, Abundance of soil faunal community appeared significantly increase from 52 916.1 ind/m2 in Chinese fir plantation to 86 618.7 ind/m2 in the fallow blanks of clear-cutting Chinese fir plantation (P = 0.03), that was close to 78298.4 ind/m2 in the evergreen broad-leaved forest ( P = 0.75). The increases were mainly attributed to the increase of Nematoda, Enchytraeidae, Acarina and Collembola, which contributed 62.84%, 26.57%, 4.74% and 2.26% of the increase respectively. However, the diversity of soil faunal community changed slowly. The Shannon diversity index increased by 25.71% from Chinese fir plantation to the fallow blanks of clear-cutting Chinese fir plantation, which reached 88.88% of the secondary evergreen broad-leaved forest. By comparing the abundance and diversity of soil fauna of the three forest types , it is obvious that the restoration rate of diversity of soil fauna is slower than that of abundance. Since the community composition, diversity and abundance characteristics of the abandoned land are closer to the secondary evergreen broad-leaved forest than the Chinese fir plantation forest, results support the increase of ecosystem instability promotes the recovery soil organism.
