专刊征稿

金砖国家土壤微食物网

（BRICS Soil Micro-Food Web，金砖国家工商理事会农业经济组组织）

专刊背景（Background）

土壤食物网是由取食作用形成的地下生物网络，在支撑生态系统功能（如碳、氮循环）和提供生态系统服务（如食物生产、调节气候）等方面发挥着关键作用。作为主要的分解者，微生物对有机物质分解等功能起主导作用。此外，土壤微型动物（主要包括原生动物和线虫）由于可以直接捕食微生物，所以对有机质分解等功能也有重要的贡献。更重要的是，由于线虫数量巨大、种类繁多、在土壤生态系统中占有多个营养级、且在土壤食物网中占据中心位置，所以线虫群落分析已经被广泛应用于指示整个土壤食物网的状况。因此，由微生物-原生动物-线虫组成的土壤微食物网受到越来越多的关注。

Soil food web, as a belowground biotic network formed by trophic interaction, plays key roles in underpinning ecosystem functions such as carbon and nitrogen cycling and in delivering ecosystem services including food security and climate mitigation. As the primary decomposers, microorganisms dominantly contribute to organic matter decomposition. Also, soil microfauna mainly including protozoa and nematodes make the crucial contribution, due to their close associations with microorganisms by direct predation. More importantly, the nematode community analysis has been extensively used to indicate the entire soil food web status, because it is greatly abundant, species-rich, multi-trophic and occupies the central position within soil food web. Therefore, soil micro-food web consisting of microorganisms-protozoa-nematodes has received growing attention.

在2022金砖中国年期间，巴西、俄罗斯、印度、中国和南非五个金砖国家共同聚焦农业可持续发展问题。如上所述，土壤微食物网对于维持农业生产至关重要。本期特刊特别关注金砖国家土壤微食物网的最新研究进展，旨在促进金砖国家之间的学术交流，与世界分享相关研究成果，这对于可持续农业的土壤微食物网管理具有重要的指导意义。

During the 2022 BRICS conference, the five BRICS countries of Brazil, Russia, India, China and South Africa have together focused on sustainable agriculture. As mentioned above, soil micro-food web is important for sustaining agriculture. This special issue specially focusing on the latest advances in soil micro-food web in BRICS countries aims to promote scholarly communications among the BRICS countries and to share the relevant research achievements with the world. This will be significant for informing soil micro-food web management for sustainable agriculture.
