Abstract:

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 shows that geomorphic heterogeneity does something to soil fauna which come from Huajiang valley,Qinzhen basin and Bijie mountain. The communities and quantities of the soil animals is on the increase along the valley-mountain direction, and the percentages of Hymenoptera and Diplura are on the decrease, the percentage of Collembola is on the increase. The distributions of Diptera and Hemiptera have a positive correlation to the relative humidity. The distributions of Plesiopora and Acari have a positive correlation to the illuminance.
