摘要
从理论及实验研究的角度论述了藻类非稳态种间资源竞争研究进展。实验室内稳态条件下的竞争理论得到了大量实验验证,由于自然水体处于非稳状态,非稳态条件下藻类种间资源竞争日益成为藻类水华形成机制研究的重点。主要理论包括Tilman的R*法则和资源比假说,Grover的拾遗者-机会主义者交替竞争假说(VIS),中度干扰假说(IDH)及关键光强(CLIH)假说。这些假说的提出丰富了藻类资源竞争的理论体系,为研究自然状态下藻类增殖和竞争行为奠定理论基础。今后的藻类种间资源竞争的研究重点为非稳态下物理条件变化以及物理、化学和生物资源共同变化下藻类种间关系及生物多样性的研究。
Algae competition for resources was discussed from the theory and test of view in this article, under steady-state and under non-steady-state research of algae resource competition was validated largely by experimentations. Research of algae resource competition became more and more important in water-bloom research region owing to non-steady-state of natural water body. Major theories in this region are Tilman＇s R^＊ rule and resource ratio hypothesis, Groer＇s Gleaner- Opportunist Trade-Off（ VIS ）, Intermedial Disturbance Hypothesis（IDH） and the Critical Light Intensity Hypothesis（ CLIH ）. The algae resource competition theory system and experimentation directions are enriched by those hypothesis, which establish the theory foundation of algae massive growth and resource competition. The emphases of algae resource competition research will be focused on the research of relationships or biodiversity of algae species under physics factor varieties and physics, chemistry and biology complex varieties conditions.
