越来越多的研究表明，农业生态系统功能的内部调节水平在很大程度上取决于现有植物和动物生物多样性的水平。在农业生态系统中，生物多样性在粮食生产之外提供各种生态服务，包括营养物质的再循环、调节小气候和当地水文过程、抑制有害生物和有毒化学品的解毒。本文详细探讨了生物多样性在保障作物保护和土壤肥力中的作用。由于生物多样性介导的更新过程和生态服务在很大程度上是生物性的，它们的持久性取决于农业生态系统中生物完整性和多样性的维持。介绍了提高农田功能生物多样性的农业生态系统管理和设计的各种选择。(C) 1999 Elsevier Science B.V.版权所有
Increasingly research suggests that the level of internal regulation of function in agroecosystems is largely dependent on the level of plant and animal biodiversity present. In agroecosystems, biodiversity performs a variety of ecological services beyond the production of food, including recycling of nutrients, regulation of microclimate and local hydrological processes, suppression of undesirable organisms and detoxification of noxious chemicals. In this paper the role of biodiversity in securing crop protection and soil fertility is explored in detail. It is argued that because biodiversity mediated renewal processes and ecological services are largely biological, their persistence depends upon the maintenance of biological integrity and diversity in agroecosystems. Various options of agroecosystem management and design that enhance functional biodiversity in crop fields are described. (C) 1999 Elsevier Science B.V. All rights reserved.
