【摘要】：[目的]探討巨桉林中螞蟻群落的生態(tài)狀況及植被變化后螞蟻群落的響應(yīng),為今后土地利用方式的選擇優(yōu)化及生態(tài)恢復(fù)策略的制定提供依據(jù)。[方法]于2012年10月和2013年4月采用Winkler袋法調(diào)查云南省綠春縣的巨桉人工林和天然次生林中枯落物層螞蟻群落。[結(jié)果]共采集枯落物層螞蟻5亞科34屬66種2 118頭。四個樣地間枯落物層螞蟻的物種豐富度有顯著差異(GLM,t=-2.068,P=0.039),相對多度無顯著差異(GLM,t=-0.174,P=0.863),其中巨桉林E1螞蟻物種豐富度最高,N2最低;天然次生林N1螞蟻多度最高,E2最低。巨桉林枯落物層螞蟻群落結(jié)構(gòu)與天然次生林無顯著差異(ANOSIM Global R=0.5,P=0.333)。巨桉林中的指示物種為菱結(jié)大頭蟻和東方小家蟻,天然次生林中的指示物種為紅足厚結(jié)猛蟻�？萋湮飳雍穸扰c螞蟻物種豐富度顯著負(fù)相關(guān),枯落物層其它指標(biāo)與螞蟻物種豐富度和多度均無顯著相關(guān)性。[結(jié)論]干擾少、林下植被豐富的人工巨桉林對枯落物層螞蟻群落多樣性的保護(hù)具有積極意義。
[Abstract]:[objective] to study the ecological status of ant community in Eucalyptus grandis forest and the response of ant community after vegetation change, so as to provide the basis for the selection and optimization of land use mode and the formulation of ecological restoration strategy in the future. [methods] in October 2012 and April 2013, Winkler bag method was used to investigate the litter layer ant community of Eucalyptus grandis plantation and natural secondary forest in Luchun County, Yunnan Province. [results] A total of 2 118 species and 66 species of litter layer ants belonging to 34 genera and 5 subfamilies were collected. There was significant difference in species richness of litter layer ants between four plots, but there was no significant difference in relative abundance between GLMMtTU and 2.068, and there was no significant difference in relative abundance. Among them, the species richness of E1 ants in Eucalyptus grandis forest was the highest and that of E1 ants was the lowest, and that of N1 ants in natural secondary forest was the highest and that of E2 was the lowest. There was no significant difference between ant community structure in litter layer and natural secondary forest in eucalyptus grandis forest. The indicator species in Eucalyptus grandis forest are Rhombohedral species and Oriental small ants, while in natural secondary forest they are Red-footed and ferocious ants. There was significant negative correlation between litter layer thickness and ant species richness, but there was no significant correlation between other indexes of litter layer and ant species richness and abundance. [conclusion] the artificial Eucalyptus grandis forest with abundant understory vegetation has positive significance for the protection of ant community diversity in litter layer.
