农业生态系统的同质化和集约化是对生物多样性的最重要威胁之一，与传粉媒介、土壤生物群和生态系统功能的下降有关。多样性已被提议作为恢复农业景观生态系统功能的一种方式。为了管理农业用地以实现多种生态系统功能，需要有证据证明多样化对功能不同的分类群的影响。我们通过对161篇同行评审文章进行全球荟萃分析，致力于缩小这一知识差距，这些文章讨论了六个不同功能群的丰度和丰富性：自养生物、分解者、天敌、害虫、传粉者等。我们发现，相对于简化的农业系统，多样化的农业系统平均将整体物种丰富度提高了26%。然而，多样化的耕作对总体平均丰度的影响很弱。我们的研究表明，多样化的农业系统提高了有益物种的丰度和丰富度，同时减少了害虫的丰度（例如，杂草、食草动物），从而为农业生产和生物多样性带来好处。多样化耕作系统对总体平均物种丰富度的积极影响在更简化的景观中的农场更强，即，那些远离自然和半自然生境或在1公里半径内自然植被比例较低的地区。传粉昆虫的丰度和丰富度在远离自然和半自然栖息地的多样性农业地块中最高。相反，接近这些自然和半自然的栖息地（<250米）增加了多样化的农业系统对天敌的丰度的积极影响，同时减少了害虫的数量。我们的研究结果增加了大量证据，呼吁重新调整政策，法规和国际议程，以促进，支持和激励采用多样化的农业实践来支持生物多样性。多样化计划的空间规划应考虑农场的景观环境，以确保干预的最大效益。
Homogenisation and intensification of agricultural ecosystems are among the most important threats to biodiversity, linked to declines in pollinators, soil biota and ecosystem functioning. Diversification has been proposed as a way to restore ecosystem functioning in agricultural landscapes. To manage agricultural land for multiple ecosystem functions, evidence is needed of the effect of diversification on functionally distinct taxa. We contribute to closing this knowledge gap through a global meta-analysis of 161 peer-reviewed articles addressing the abundance and richness of six distinct functional groups: autotrophs, decomposers, natural enemies, pests, pollinators, and other. We found diversified farming systems increased overall species richness by 26% on average, relative to simplified farming systems. However, the effect of diversified farming on the overall mean abundance was weak. Our study shows diversified farming systems enhanced the abundance and richness of beneficial species while reducing the abundance of pests (e.g., weeds, herbivores), thus providing benefits for both agricultural production and biodiversity. The positive effect of diversified farming systems on the overall mean species richness was stronger in farms in more simplified landscapes, i.e., those that are further from natural and semi-natural habitats or have a lower proportion of seminatural vegetation in a 1 km radius. Pollinator’s abundance and richness were highest in diversified farming plots located far away from natural and semi-natural habitats. In contrast, proximity to these natural and semi-natural habitats (<250 m) increased the positive effect of diversified farming systems on natural enemies’ abundance, while reducing the number of pests. Our results add to the body of evidence calling for the repurposing of policies, regulations, and international agendas to promote, support and incentivize the adoption of diversified farming practices for supporting biodiversity. Spatial planning of diversification schemes should consider the landscape context of farms to ensure the greatest benefit of intervention.
