【摘要】：[目的]探討天然次生林和人工林及人工林樹種選擇對樹冠層螞蟻群落多樣性的影響。[方法]運用樹棲螞蟻陷阱法調(diào)查云南省綠春縣天然次生林和4種人工林的樹冠層螞蟻群落、植物多樣性及植物垂直密度變化。[結(jié)果](1)共采集螞蟻標(biāo)本17 998頭,隸屬于6亞科29屬68種。(2)樹冠層螞蟻多度:紫膠林-玉米混農(nóng)林紫膠林桉樹林橡膠林天然次生林。(3)樹冠層螞蟻豐富度:紫膠林-玉米混農(nóng)林紫膠林天然次生林橡膠林桉樹林。(4)樹冠層螞蟻ACE估計值:紫膠林-玉米混農(nóng)林紫膠林天然次生林桉樹林橡膠林。(5)樹冠層螞蟻多度和豐富度與枯落物蓋度、300 cm處垂直密度和喬木郁閉度呈顯著或極顯著負(fù)相關(guān),而與植物蓋度顯著正相關(guān);ACE估計值與枯落物蓋度、草本植物蓋度和喬木郁閉度顯著負(fù)相關(guān),與175 199.9 cm區(qū)段內(nèi)垂直密度顯著正相關(guān)。[結(jié)論]人工林對螞蟻多樣性保護(hù)有一定積極作用,尤其選擇鄉(xiāng)土樹種保護(hù)效果更顯著,對人工林進(jìn)行合理的管理有利于保護(hù)生物多樣性。
[Abstract]:[objective] to study the effect of tree species selection on the diversity of ant community in tree canopy in natural secondary forest, artificial forest and artificial forest. [methods] the tree canopy ant community, plant diversity and vertical density of natural secondary forest and four artificial forests in Luchun County, Yunnan Province, were investigated by the method of arboreal ant trap. [results] (1) A total of 17 998 ant specimens were collected. It belongs to 68 species belonging to 29 genera of 6 subfamilies. (2) Ant abundance in canopy layer: natural secondary forest of rubber forest in Lac forest and mixed agriculture forest with maize. (3) ant richness in canopy layer: lacca forest and mixed agriculture forest with maize in lac forest. (3) ant abundance in rubber forest in eucalyptus forest. Natural secondary forest rubber forest eucalyptus forest. (4) ACE estimate of canopy ant: rubber forest of natural secondary forest eucalyptus forest. (5) ant abundance and richness of canopy layer and litter coverage. There was a significant negative correlation between vertical density and canopy density at 300 cm, but a positive correlation between vertical density and canopy density. ACE estimation was negatively correlated with litter coverage, herbaceous coverage and tree canopy density, and positively correlated with vertical density in 175 199.9 cm. [conclusion] artificial forest has a positive effect on ant diversity protection, especially the conservation effect of native tree species is more remarkable. Reasonable management of plantation is beneficial to the conservation of biodiversity.
