论文摘要：Agricultural ecosystems are facing increasing environmental changes. Revealing ecological stability of belowground organisms is key to developing management strategies that maintain agricultural ecosystem services in a changing world. Here, we collected soils from adjacent pairs of maize and rice fields along large spatial scale across Eastern and Southeast China to investigate the importance of core microbiota as a predictor of resistance of soil microbiome (e.g. bacteria, fungi and protist) to climate changes and nutrient fertilization, and their effect on multiple ecosystem functions, representing key services for crop growth and health in agro-ecosystems. Soil microbiome in maize soils exhibited stronger resistance than that in rice soils, by considering multiple aspects of the resistance index, for example, community, phylogenetic conservation and network complexity. Community resistance of soil microbiome showed a geographic pattern, with higher resistance at lower latitudes, suggesting their stronger resistance in warmer regions. Particularly, we highlighted the role of core phylotypes in enhancing the community resistance of soil microbiome, which was essential for the maintenance of multifunctionality in agricultural ecosystems. Our results represent a significant advance in linking core phylotypes to community resistance and ecosystem functions, and therefore forecasting agro-ecosystems dynamics in response to ongoing environmental changes. These suggest that core phylotypes should be considered a key factor in enhancing agricultural sustainability and crop productivity under global change scenarios
农业生态系统面临着日益严重的环境变化。在不断变化的环境中，揭示地下生物的生态稳定性是维持农业生态系统服务管理战略的关键。本研究以中国东部和东南部相邻种植10年以上的玉米和稻田为研究对象，在大空间尺度上研究土壤核心微生物群对土壤微生物群(细菌、真菌和原生生物)对气候变化和养分添加的抗性的预测作用，以及它们对多种生态系统功能的影响，揭示了土壤微生物群对作物生长和健康的重要作用。从群落、系统发育和网络复杂性等抗性指数的多个方面来看，玉米土壤中微生物的抗性比水稻土壤中微生物的抗性更强。土壤微生物的抗性呈现出低纬度地区的抗性较高的地理格局，表明温暖地区的抗性较强。该研究特别强调了核心菌群在增强土壤微生物群落群体抗性方面的作用，这对于维持农业生态系统中的多功能性至关重要。此外，该研究结果显示，将核心菌群与群落抗性和生态系统功能联系起来，可以预测农业生态系统动态，以应对持续的环境变化。这些结果表明，在全球变化情况下,核心菌群应被视为提高农业可持续性和作物生产力一个关键因素。
