摘  要：
[目的]深入了解川西亚高山退化森林生态系统恢复与重建过程中的生态学特征。[方法]2007年在理县毕蓬沟森林样地内,对采伐后人工种植的云杉纯林及人工天然混交林土壤动物群落进行了研究。[结果]川西亚高山针叶林土壤动物群落以线虫纲、蜱螨目、弹尾目为优势类群,以倍足纲、猛水蚤目、轮虫纲、线蚓科、双翅目幼虫等为常见类群。川西亚高山针叶林土壤动物群落垂直分布仍具有表聚性,但有向下层移动的趋势。人工云杉纯林土壤动物群落类群数及多样性指数DG低于人工天然混交林,但并无显著差异。[结论]人工纯林较之混交林退化程度还不高,通过对植被组成和结构的调控,有望增加其生态系统内土壤生物的多样性。

摘  要：
[Objective] The study aimed to understand deeply the ecology dynamics in the process of subalpine degraded forest ecosystem restoration and reconstruction in western Sichuan.[Method] The soil animal community in artificially planted Picea aspoerata pure plantation and artificial natural mixed plantation after cutting was studied in forest sample land in Bipenggou in Lixian County in 2007.[Result] In subalpine coniferous forest in western Sichuan,the Nematoda,Acarina and Collembola were the dominant groups of soil animal community and Diplopoda,Harpacticoida,Rotatoria,Enchytraeidae and Diptera(larva) were the frequent groups.The vertical distribution of soil animal community in ubalpine coniferous forest in western Sichuan still had surface accumulation,but had the tend of adown moving.Group number and DG(Density-groups) index of soil fauna in P.aspoerata pure plantation was lower than that of the mixed plantation,but without significant difference.[Conclusion] the degradation of P.aspoerata pure plantation was not severe.The biodiversity of soil organisms in its ecosystem would be enhanced through the regulation of the composition and structure of the vegetation.
