资源竞争理论及其研究进展

A review on resource competition theory

介绍了国外近 2 0年来发展起来的一种新的竞争理论资源竞争理论。该理论包含两个主要假说 ,即R 法则和资源比假说。资源竞争理论已在微生物、微藻、高等植物及浮游动物中得到广泛的实验验证。阐述了资源竞争理论形成的基础Monod竞争模型和Droop竞争模型。对两种模型在稳态及非稳态条件下的预测性能作了比较 :对于稳态下的竞争 ,两种模型皆能做出较好的预测 ,但使用Monod模型更为简便 ;对于非稳态下的竞争 ,使用Droop模型更为合理。

This paper introduces a new competition theory resource competition theory,which includes R * rule and resource ratio hypothesis.It has been well tested with microorganisms,phytoplankton,plants and zooplankton.The basic building blocks of this theory are the Monod model and the Droop model of competition.These two models can make similar predictions for equilibrium studies.But considerable simplification is achieved using the Monod model.The Droop model can make a better prediction for non equilibrium studies.At last,the future of resource competition theory is prosected.
