植物种间的竞争机制

The Mechanism of Plant Interspecific Competitions

从资源吸收与消耗两方面着手,建立了两种植物为一种资源竞争的模型;和两种植物为两种资源竞争的模型,在这两个模型的基础上,分析了植物种间竞争的机制,讨论了谢氏耐性定理与竞争机制的关系,最后分析了植物为适应长期竞争压力所发展的对策。

In the paper, first, the competitional model between two plant species for akind of resource is constructed under the absorption and consumption of resource. Second, the competitional model between two plant species for two kinds of resources is constructed. On the basis of the two models, plant competitional mechanism is analyzed. Then,the relationship between the Shelford's tolerance law and plant competition is discussed. At last, the plant competitional strategies adapting to the competition pressure are elucidated.
