摘要: 阐述了草地农业生态学的内涵、发展过程、前沿领域和发展趋势.草地农业生态系统的界面理论、结构与功能、系统耦合与系统相悖以及系统健康评价是该学科的4个前沿领域.草地农业生态系统存在3个基本界面,即草丛地境、草地动物以及草畜生产经营管理界面,研究发生于各个界面的一系列生态学过程,是揭示系统行为特征的关键.草地农业生态系统有4个生产层,即前植物、植物、动物和外生物生产层,系统耦合与系统相悖是生产层之间互作的2个重要概念.不同生产层之间的系统耦合,可产生系统进化,多方面释放系统潜势.生态系统健康水平是其结构和功能的反映,健康评价是对其有序度和服务价值的度量.

关键词: 草地农业生态系统, 界面, 系统耦合, 系统相悖, 健康评价

Abstract: The connotation, progress, research frontiers and developmental trend of grassland agroecology are discussed in this paper.The interface theory, structure and function, coupling and discordance, and health assessment of grassland agroecosystems were recognized as the four research frontiers of the discipline. There exist three primary interfaces in a grassland agroecosystem, i.e.,vegetation site, grassland animal and production management. Research into a series of the ecological processes that occured at these interfaces is the key to revealing the features of the system behavior. There are four sections in a grassland agroecosystem, i.e.,pre-plant, plant, animal and post biotic sections. System coupling and discordance are the two important concepts to describe interactions among the production sections. System coupling among the sections can lead to system improvement by exerting the potential of system capacity. Health of an ecosystem is a reflection of its structure and function, and health assessment is a measurement of its orderliness and service value.

Key words: Grassland agroecosystem, Interface, System coupling, System discordance, Health assessment
