摘要:
为研究毛竹 Phyllostachys heterocycla 扩张对土壤甲螨群落的影响,2017 年冬季在从化流溪 河森林公园内,采用样方调查法分别对毛竹林、竹阔混交林、阔叶林 3 种林地进行调查取样,通过室内 Tullgren 漏斗法对土壤甲螨进行分离和鉴别。结果表明:共捕获 5 607 头甲螨,隶属于 67 属,优势属为角 单翼甲螨属、大奥甲螨属和大头甲螨属。竹林土壤甲螨数量最多;但阔叶林样地的土壤甲螨类群数最多, 群落的 4 种多样性指标亦最高,毛竹扩张导致竹林地下土壤甲螨数量增加但多样性降低,各样地土壤甲 螨群落相似性和 MGP 分析得出类似的结论。

Abstract:
In order to better understand the effect of bamboo (Phyllostachys heterocycla) expending on community structure of soil oribatid mite, an experiment was conducted in Conghua Liuxihe Forest Park. The bamboo forest, bamboo and broad-leaved mixed forest and broad-leaved forest were investigated and sampled by quadrat method in winter of 2017. Soil oribatid mites were extracted and identified by a modified Tullgren method. The results showed that a total of 5 607 oribatid mites were captured, belonging to 67 genera. The dominant genera were Rostrozetes, Lasiobelba and Megalotocepheus. The individual number of soil oribates in bamboo forests was larger than other forests. However, the number of family of soil oribates in broad-leaved forest was the highest among three type of forests, and the four diversity indices of community were also the largest. Our results indicated bamboo forest expending was conducive to increase the individual number of oribatid mites, but not on the diversity of soil oribates communities. Similar conclusions were drawned by similarity of soil oribatid mite communities and MGP analysis.
