农业生态学是一门新兴学科，主要研究农业生物与其环境之间的相互作用关系，对全球可持续发展具有重大影响。从分子到景观不同尺度，涉及农业面源污染、农业资源高效利用、农业生态模式、农业景观与生态服务、农业与全球变化等方面，回顾了2020年农业生态学的重要科技进展和突破，认为可持续食物生产系统的颠覆性创新和人类健康导向的食物链管理是今后农业生态学的研究重点。
As a new subject emerging with the green revolution, agroecology focuses on the total relationships between agricultural organisms and both their organic and inorganic environments, which is playing a key role in global sustainable development. From molecular to landscape scale, this paper reviews the achievements in non-point source pollution, highefficient use of agricultural resource, establishment of agro-ecosystem, agricultural landscape and its ecosystem service, and impact of global climate change on agriculture. A game-changing innovation of sustainable food production system and food chain management for human health are becoming the research hotspots in the future agroecology.
