对大兴安岭不同冻土带土壤动物进行的研究,将该区土壤动物划分为植食性、腐食性和捕食性三个功能类群。土壤动物功能类群的水平分布与地温的相关性表明,不同冻土带腐食性土壤动物总的生物量和地温的相关系数为-0.999,呈显著负相关(P<0.05);不同冻土带捕食性土壤动物总的生物量和地温的相关系数为-0.997,呈显著负相关(P<0.05)。土壤动物功能类群的垂直分布与地温的相关性表明,岛状融区冻土带土壤动物功能类群的垂直分布与8月份地温值呈显著正相关,岛状融区冻土带的腐食性动物的垂直分布与8月份地温显著正相关。各功能类群的个体数量相关分析结果表明,腐食性动物和捕食性动物相关系数为0.8723,呈显著正相关(P<0.05);生物量相关分析结果表明,腐食性动物和捕食性动物相关系数为0.7551,呈显著正相关(P<0.01)。
Soil animals in the different tundra of the Greater Hinggan Mountains were studied, and the fauna and fauna were divided into three functional groups: herbivorous, rotting and predatory. The correlation between the soil animal functional taxa and the ground temperature indicated that the correlation coefficient between total biomass and ground temperature of the soil animal in different frozen soils was -0.999 (P <0.05) The correlation coefficient of total biomass and ground temperature of sexual soil animal was -0.997, showing a significant negative correlation (P <0.05). The correlation between the vertical distribution of soil fauna functional groups and the soil temperature indicated that the vertical distribution of soil fauna functional groups in the island-like frozen zone was positively correlated with the August soil temperature, while that in the island melted tundra The vertical distribution is positively correlated with the ground temperature in August. Correlation analysis showed that there was a significant positive correlation between the correlation coefficient of the number of individuals and the predators (0.8723, P <0.05). The biomass correlation analysis showed that the correlation coefficient between the number of the predators and the predators was 0.7551, there was a significant positive correlation (P <0.01).
