摘要
"现代农业"生产力高,但生物多样性简单化、生物之间的相互作用及其生态学效应常常被忽略,其生产力的稳定性主要依赖于化学肥料、农药、灌溉和高产品种等的投入。传统农业则是利用当地生物多样性(物种多样性和遗传多样性)和生物之间的相互作用来产出食物和维持系统的稳定。因而现代农业能否借鉴传统农业对生物多样性利用的经验,将工业化模式的现代农业转换为生物多样性利用与现代技术相结合的农业受到关注。本文分析了农业系统中生物多样性的特点及农业方式对农业生物多样性的影响;综述了农业系统中生物多样性利用模式与效应方面的研究进展;讨论了在现代农业系统中,利用生物多样性需要开展的研究,即区域上如何布局农业景观多样性,农田内如何根据生物之间的互惠关系配置物种多样性的种养体系,如何建设与生物多样性利用相应的田间设施和发展新型的农业机械、并建立以信息化为基础的管理体系。
