研究了非生长季节向生长季节转换过程中川西高山森林土壤动物群落结构和多样性的特征,以期解释土壤动物群落的自适应变化.从川西高山原始针叶林下6种小生境共捕获大型土壤动物为3 167只,隶属于2门8纲16目,以林隙小生境内大型土壤动物的个体密度(530.71只/m2)和类群数量(10类)最高;中小型土壤动物为10 585只,隶属于4门8纲8目,以苔藓小生境内中小型土壤动物的个体密度(148 400.00只/m2)和林隙小生境中类群数(8类)最高.林隙小生境中的大型土壤动物群落Shannon-Wiener多样性指数H’和Pielou均匀性指数J最高,Simpson优势度指数C最低,但倒木小生境表现出相反的趋势.林下凋落物小生境的中小型土壤动物群落多样性指数H’最高,C最低,但灌木小生境则相反.
This paper studied the characteristics of soil animal community structure and diversity during the conversion from non-growing season to growing season in order to explain the adaptive changes of soil animal community.From 6 kinds of niches under the native coniferous forest in western Sichuan, There were 3 167 animals belonging to 2 classes, 8 classes and 16 orders, with the highest individual density (530.71 / m2) and the highest number of taxa (10 species) in the niche niches. The number of small and medium sized soil animals was 10 585, Belonging to 4 classes, 8 classes and 8 orders, with the highest density (148 400.00 / m 2) and the lowest number of species (8) in the moss niche in the moss niche.Marginous soil fauna The community Shannon-Wiener diversity index H ’and Pielou evenness index J were the highest while the Simpson dominance index C was the lowest, but the inverted wood niche showed the opposite trend. The diversity index of small and medium soil fauna in litter niche ’The highest, C the lowest, but the shrub niche is the opposite.
