摘要：【目的】为探讨兼性互利关系对节肢动物群落及春砂仁生产的影响。【方法】于2015年5月和9月,采用目光搜寻法对云南省墨江县雅邑镇3种类型样地(样地I:纯春砂仁地;样地II:不放养紫胶虫的紫胶林—春砂仁混农林;样地III:放养紫胶虫的紫胶林—春砂仁混农林)的节肢动物群落进行调查,同时调查春砂仁的生产情况(开花结实)。【结果】(1)物种组成及多度:样地I采集节肢动物851头,36种;样地II采集节肢动物1 097头,30种;样地III采集节肢动物1 494头,37种。(2)多样性比较:3种类型样地间的节肢动物、益虫和害虫的物种丰富度均无显著差异;3种类型样地间的节肢动物和益虫多度有显著差异,由多到少排序为:III>II>I;3种类型样地的害虫多度无显著性差异。(3)群落结构相似性:样地III节肢动物群落结构与样地I和样地II不相似。(4)春砂仁生产情况比较:3种类型样地间的春砂仁开花总数、授粉率无显著差异;3种类型样地间春砂仁的正常果实数和不正常果实数有显著差异,样地III正常果实数最高,不正常果实数最低。【结论】兼性互利关系显著增加了春砂仁地中益虫的多度,改变节肢动物群落结构,显著增加春砂仁的产量,对生态系统服务有积极影响。
In order to explore the effects of ties and Amomum villosum production in lac plantation-A facuhative mutualism on arthropod communi- villosum agroforest. [ Method ] Investigations of arthropod communities and A. villosum productions were conducted by searching methods in three types sites of Yayi, Mojiang Couty, Yunnan Province in May and September, 2015 （plot I： A. viUo- sum plantation; plot II： lac plantation-A, villosum agroforestry without lac insect infestation; plot III： lac plantation- A. viUosum agroforestry with lac insect infestation）. [ Results ] （ 1 ） Species composi- tions and abundance： 851 arthropod individuals were collected from the plot I, representing 36 spe- cies; 1 097 arthropod individuals were collected from the plot II, representing 30 species; 1 494 ar-thropod individuals were collected from the plot III, representing 37 species. （2） Diversity compari- sons： there were significant differences of arthropod abundance and beneficial insect abundance among three sites. Arthropods and beneficial insect abundance ranked as III〉 II 〉 I ; but there were no signif- icant differences of arthropod species richness and pest abundance. （3） Community structures： arthro- pod community structures of plot III were dissimilar with those in plot II and I. （4） A. villosum produc- tions： there were no significant differences in terms of A. villosum blossom quantities and pollination rates among different plots. Number of normal fruits and abnormal fruits of A. villosum had significant differences among different plots; plot III had the highest normal fruits and the lowest abnormal fruits. [ Conclusion] Faeuhative mutualism increased the abundance of beneficial insects, changed the ar- thropod community structures, and increased the A. villosum productions, which had positive effects on ecosystem servers.
