云山国家森林公园土壤动物资源生态特征

1998年5月至2001年5月对云山国家森林公园土壤动物资源进行了生态特征研究,共获得土壤动物9769个,隶属6门13纲31个类目。亚热带土壤动物的类群在这里几乎都有分布。其中优势类群为蜱螨目、弹尾目及线虫类3类;常见类群有膜翅类、双尾目、原尾目、线蚓类、双翅目5类;其余为稀有类群。通过与我国东西方向及其南北方向上典型土壤动物生态群落的分析比较,研究过程发现,受其地表生物多样性的影响,云山土壤动物资源种群丰富;原始群落结构完整;区系组成地带过渡性明显;山体顶部灌丛地段节肢动物有个体偏大的生态特征。研究结果表明:地处我国南岭、雪峰山及滇黔桂地区3种不同类型山系过渡地带的云山国家森林公园,作为自然保护区,不但是一个资源丰富的地表生物生态基因库,同时还是一个异常宝贵的地下生物生态基因库。

Study on the ecological characteristic of soil animal resources in Yunshan National Forest Park

From1998to2001,we studied the ecological characteristics of soil animal resources in the Yunshan National Forest Park of China.Of the9769total soil animals,the invertebrates include31genera in13classes and6phyla.Almost all subtropical soil animals are found to be distributed in Yunshan National Forest Park.Among them,Acarina,Collembola and Nematoda are dominant species;Hymenoptera,Diplura,Protura,Enchytraeidae and Diptera are common species;and the rest is rare species.Analysis and comparison of the community ecosystem of soil animals indicate that affected by terrestrial biodiversities,there are abundant soil animal species with complete primitive community structure,apparent zonal transitivity of faunal composition and mountaintop Arthropoda of individual partial heavy ecological characteristic.The research results show that the Yunshan National Forest Park situated in Nanling,Xuefengshan and Yunnan-Guizhou Plateau,the three different kinds of mountain system of China,is not only a surface bio-ecological gene pool with rich resources but also an extremely precious underground bio-ecologi-cal gene pool.
