基于两种生态学理论监控草地质量

准确理解中度干扰假说和冗余结构理论，并将两者有机结合，有助于草地质量的调控。关于这两种生态学理论所取得的相关研究成果，对于认识和理解草地生态系统的结构、功能、演替以及生产潜力具有积极作用，这也使其逐步成为指导草地畜牧业生产实践十分重要的科学依据。阐述了草地质量及其具体表示指标，以及中度干扰假说和冗余结构理论与草地质量的关系，并论述了中度干扰假说和冗余结构理论在封育、中度放牧、毒害草防治等管理措施条件下草地质量变化的生态学过程中的作用。

Monitoring and Controlling Pasture Quality based on Two Ecological Theories

The accurate understand of the intermediate disturbance and redundancy construction theories as well as the organic combination of them is helpful for the regulation of grassland quality. Research results regarding these two ecological theories have played an active role in understanding the structure, function, succession and potential productivity of grassland ecosystem, and have gradually become a very important scientific basis for guiding grassland animal husbandry production practice. This paper expounds the control of grassland quality and its specific indicators, elucidates the association between these two ecological theories and grassland quality, and discusses the role of these two ecological theories in the ecological process of grassland quality change under the management measures of enclosure, moderate grazing and poisonous weed control.
