摘　　要：大型土壤动物蚯蚓对土壤生态功能具有重要影响。本研究采集了云南省6个气候带的1984个蚯蚓样本,探讨云南省蚯蚓的空间分布特征。结果表明:神女辛石蚓和梯形流蚓为云南省优势蚯蚓物种。云南省温带地区的蚯蚓物种最多,其次为北热带、北亚热带、中亚热带、高原气候带和南亚热带;蚯蚓密度表现为高原气候带(70.7 ind·m^(-2))>温带(62.4 ind·m^(-2))>北亚热带(55.9 ind·m^(-2))>北热带(37.7 ind·m^(-2))>中亚热带(37.7 ind·m^(-2))>南亚热带(22.7 ind·m^(-2));蚯蚓生物量为北亚热带(27.4 g·m^(-2))>北热带(24.5 g·m^(-2))>南亚热带(19.1 g·m^(-2))>温带(17.0 g·m^(-2))>中亚热带(15.3 g·m^(-2))>高原气候带(12.5 g·m^(-2))。不同的气候带类型直接影响蚯蚓生物量,此外,土壤含水率、有机质、全氮等土壤特性对蚯蚓群落也有显著影响。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 earthworm species in Yunnan Province. The highest diversity of earthworm species was found in the temperate zone, followed by the northern tropics, northern subtro-pics, central subtropics, plateau climatic zone, and southern subtropics. 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.
