摘要
贵州喀斯特高原独特的地理环境对土壤动物分布的影响研究较少,通过对花江喀斯特高原峡谷,清镇喀斯特高原盆地与毕节喀斯特高原山地天然灌草丛中土壤动物群落的分析,得知贵州喀斯特高原地貌异质性对土壤动物分布有一定影响:(1)沿峡谷—山地方向,土壤动物类群不断增加,膜翅目、双尾目比重不断减少,弹尾目比重不断增加。(2)双翅目与半翅目的分布与地表空气的相对湿度呈正相关关系。(3)近孔寡毛目和蜱螨类的分布与地表的光照度呈正相关关系。
The research about the distribution of soil fauna in the unique geographical environment on Guizhou karst plateau is a lack of consideration.Research on soil fauna in natural shrub-meadow showed that geomorphic heterogeneity done something to soil fauna which come from Huajiang valley,Qinzhen basin and Bijie Mountain.The communities and quantities of the soil animals was on the increase along the valley-mountain direction,and the percentages of Hymenoptera and Diplura were on the decrease,the percentage ofCollembola was on the increase.The distributions ofDiptera andHemiptera had a positive correlation to the relative humidity.The distributions ofPlesiopora andAcari had a positive correlation to the illuminance.
