云南省不同气候带蚯蚓分布特征
Distribution characteristics of earthworms in different climatic zones of Yunnan Province,Southwest China
摘要
Abstract
Earthworms,as large soil animals,play a crucial role in soil ecological functions.We investigated the spatial distribution characteristics of earthworms by collecting 1984 earthworm individuals from six climatic zones in Yunnan Province.The results showed that Octolasion tyrtaeum and Aporrectodea trapezoides were the dominant earth-worm species in Yunnan Province.The highest diversity of earthworm species was found in the temperate zone,fol-lowed by the northern tropics,northern subtro-pics,central subtropics,plateau climatic zone,and southern sub-tropics.In terms of density,the order was plateau climatic zone(70.7 ind·m-2)＞temperate zone(62.4 ind·m-2)＞northern subtropics(55.9 ind·m-2)＞northern tropics(37.7 ind·m-2)＞central subtropics(37.7 ind·m-2)＞southern subtropics(22.7 ind·m-2).Regarding biomass,the order was northern subtropics(27.4 g·m-2)＞northern tropics(24.5 g·m-2)＞southern subtropics(19.1 g·m-2)＞temperate zone(17.0 g·m-2)＞central subtropics(15.3 g·m-2)＞plateau climatic zone(12.5 g·m-2).Climate zones exerted a direct influence on the biomass of earthworms.Furthermore,soil characteristics,including soil moisture,organic matter,and total nitrogen content significantly impacted earthworm communities.关键词
