摘要:

线虫作为指示生物,其分布与数量特征能有效指示土壤与植物健康状况。环境变化对地下生态系统产生深远影响,在资源与环境两个层面直接或间接地影响土壤线虫群落。研究表明,环境变化对土壤线虫的影响因生态系统类型而异,且短期扰动和长期扰动的效应亦有所不同。从土壤生态学的视角,综述了森林、草原、农田、湿地和荒漠等多种生态系统中线虫分布的空间异质性及其对典型环境变化的响应。提出未来可以针对特定生态系统和线虫类型开展研究,全面评估土壤线虫在各类生态系统中的作用,促进生态系统可持续发展。

Abstract:

As bioindicators, soil nematodes’ distribution patterns reflect soil-plant health. Environmental changes regulate nematode communities via resource-environment pathways, with impacts varying across ecosystems and disturbance durations. Studies indicated that these effects varied across ecosystem types, with differing responses to short-term and long-term disturbances. From the perspective of soil ecology, this review systematically examined the spatial heterogeneity of nematode distribution and their responses to typical environmental changes in forests, grasslands, farmlands, wetlands and deserts. Future research should focus on the effects of specific trophic groups of nematodes, comprehensively assess their roles across ecosystems and contribute to ecosystem sustainability.
