在不同疏密程度草本地共捕获大型土壤动物61只,分别隶属3门7纲14类.经研究得出结论:优势类群为蜘蛛目和膜翅目;草本(密)H’指数最高、草本(疏)e指数最高,草本(无)c指数最高;空间分布上大型土壤动物类群数和个体数量均为草本(密)〉草本(疏)〉草本(无),表聚现象明显;在群落相似性系数上草本(疏)和草本(密)表现出中等相似,草本(无)和草本(密)表现出明显中等不相似.
在不同疏密程度草本地共捕穫大型土壤動物61隻,分彆隸屬3門7綱14類.經研究得齣結論:優勢類群為蜘蛛目和膜翅目;草本(密)H’指數最高、草本(疏)e指數最高,草本(無)c指數最高;空間分佈上大型土壤動物類群數和箇體數量均為草本(密)〉草本(疏)〉草本(無),錶聚現象明顯;在群落相似性繫數上草本(疏)和草本(密)錶現齣中等相似,草本(無)和草本(密)錶現齣明顯中等不相似.

According to the research of 61 soil macrofauna,which belong to 3 phylums,7 Classes,14 kinds,under different density degree of the herb,we arrive at a conclusion:superiority group are Araneida and Hymenoptera;H’ index in herb(dense) is the highest;e index in herb(sparse) is the highest;c index in herb(none)is the highest;group and individual number of soil macrofauna in spatial distribution are herb(dense)〉herb(sparse)〉herb(none),and another surface aggregation phenomenon;herb(sparse) and herb(dense) display medium in the community similarity coefficients,and herb(none) and herb(dense) display obviously medium not similar.
