【摘要】：为探明热带森林蚂蚁巢穴的分布特征及其影响因素,采用样方法研究了西双版纳不同演替阶段热带森林定居巢穴蚂蚁的种类及其巢穴的密度、盖度和空间分布特征,并分析了土壤理化环境与蚂蚁种类总数、巢穴密度及盖度的相关性。结果表明,不同演替阶段热带森林蚂蚁种类总数、巢穴的密度及盖度大小顺序为:小果野芭蕉(Musa acuminata)群落白背桐(Mallotus paniculatus)群落思茅崖豆(Mellettia leptobotrya)群落,并且热带森林的演替类型显著影响蚂蚁种类总数及巢穴密度,而对巢穴盖度的影响未达到显著水平;蚂蚁种类总数、巢穴密度与土壤总有机碳和水解氮显著正相关,与土壤容重和土壤含水率显著负相关,但所选择的土壤理化指标与巢穴盖度的相关性均未达到显著水平;蚂蚁巢穴的空间分布呈随机分布格局。我们的数据表明,不同演替阶段热带森林所形成的植被类型及土壤环境状况共同影响定居的蚂蚁种类总数与筑巢密度。
[Abstract]:In order to find out the distribution characteristics and influencing factors of ant nests in tropical forests, the species, density, coverage and spatial distribution of nest ants in tropical forests of Xishuangbanna at different succession stages were studied.The correlation of soil physical and chemical environment with the total number of ant species, nest density and coverage was analyzed.The results showed that the total number of ant species in tropical forest, the density and coverage of nest in different succession stages were: Musa acuminata) community, Mallotus paniculatus) community, Mellettia leptobotrya community.The succession type of tropical forest significantly affected the total number of ant species and nest density, but the effect on nest coverage was not significant, and the total number of ant species, nest density and soil total organic carbon and hydrolyzed nitrogen were significantly positively correlated.There was a significant negative correlation between soil bulk density and soil moisture content, but the correlation between the selected soil physical and chemical indexes and nest coverage was not significant, and the spatial distribution of ant nest showed a random distribution pattern.Our data show that the total number of ant species and nesting density are affected by vegetation types and soil environmental conditions in tropical forests at different succession stages.
