We analyzed the current research status and development trend of this field at home and abroad. The results show that the number of articles published in soil nematode-related researches at home and abroad is on the rise. China's literature has an important influence on the number of publications and the frequency of citations, and the Chinese Academy of Sciences is the research organization with the most publications, thus indicating that China has a strong international academic influence in the field of soil nematodes. Soil nematodes, community structure, root-knot nematodes, diversity and other keywords are the hot research topics in this field in recent years. In the future, we should continue to deepen international collaborative research, focusing on the diversity and community structure of inter-root soil nematodes, as well as the effects of different environments on the metabolic footprints of soil nematodes.展开更多

文摘为了解土壤线虫群落结构在不同时空条件下的分布差异,于2021年春季(5月)和秋季(10月)对拉沙山区域13个综合监测样地采集的104个混合土壤样品,进行土壤线虫群落组成及多样性差异分析。利用宏基因技术共获取线虫扩增子序列变体(Amplicon Sequence Variant, ASV) 931个,隶属于2纲10目46科75属,其中2个优势类群、14个常见类群和59个稀有类群。在空间分布格局上利用方差分析及独立样本t检验方法发现,不同海拔、坡向及水陆的土壤线虫群落结构均不具有显著性差异(p>0.05);在时间分布格局上利用配对t检验方法发现,在秋季(10月)比春季(5月)的土壤线虫群落的多样性更高,且差异极显著(p<0.01)。
