Pollinator biodiversity and biomass are in decline globally. This fact accompanied by shortage and collapses of domesticated pollinator colonies, puts human food security under unprecedented threat. Many countries worldwide have adopted or intend to introduce national pollinator conservation strategies. Decisions of policy makers and other involved stakeholders are often driven by pragmatic considerations, rather than biodiversity conservation per se. At the same time, different opinions exist in the literature on the role of pollinator biodiversity versus abundance of few dominant species in crop pollination. This article critically evaluates the literature in order to understand the importance of biodiversity over abundance and to examine the effectiveness of conservation strategies. Results of this review suggest that pollinator biodiversity is critical for crop pollination quality, magnitude and resilience. Most current national pollinator conservation strategies lack comprehensive measures for maintaining pollinator biodiversity at a landscape scale.
传粉媒介生物多样性和生物量在全球范围内呈下降趋势。这一事实伴随着家养传粉媒介蜂群的短缺和崩溃，使人类的粮食安全面临前所未有的威胁。世界上许多国家已经采取或打算引入国家传粉媒介保护战略。政策制定者和其他相关利益攸关方的决策往往是出于实际考虑，而不是纯粹的生物多样性保护。与此同时，在传粉媒介生物多样性与少数优势物种在作物传粉中的丰富度的作用方面，文献中存在不同意见。本文批判性地评估了文献，以了解生物多样性相对于丰富度的重要性，并检验保护策略的有效性。这篇综述的结果表明，传粉媒介生物多样性对作物传粉的质量、规模和弹性至关重要。大多数现有的国家传粉媒介保护战略缺乏在景观尺度上维持传粉媒介生物多样性的综合措施。
