The supplies of nutrients, and their elemental stoichiometry, can have significant impacts upon the structure and function of microbial communities. This review focuses on the effects of nutrient supplies on the biodegradation of organic matter, and on the dynamics of host-pathogen interactions. Analyses of data from the literature suggest significant effects of nitrogen:phosphorus supply ratios on the microbial decomposition of organic matter, and it is argued that these stoichiometric effects may have important implications for the fate and fluxes of carbon in natural ecosystems. In addition, it is shown that the supplies of nitrogen and phosphorus to the host can strongly influence the outcome of infections in both terrestrial and aquatic plants, suggesting that resource availability and resource supply ratios potentially may have significant effects on the health of many plant communities.
营养物质的供应及其元素化学计量比，会对微生物群落的结构和功能产生重大影响。本综述着重探讨营养物质供应对有机物生物降解以及宿主 - 病原体相互作用动态的影响。对文献数据的分析表明，氮磷供应比会对有机物的微生物分解产生显著影响，并且有人认为这些化学计量效应可能对自然生态系统中碳的归宿和通量具有重要意义。此外，研究表明向宿主供应氮和磷会强烈影响陆生和水生植物感染的结果，这表明资源可用性和资源供应比可能会对许多植物群落的健康产生重大影响。
