| 摘 要： | 本文按照理论种群生态学的研究方法，从生长参数的形态功能变化和发育参数的时间变化入手，系统地研究了羊草无性系植物种群觅养生长格局与资源分配的基本规律。研究结果表明，羊草无性系种群适合于用ψ＝0.5、μ=1.0、Tr=7和Ts＝2的分配函数模型描述其觅养生长格局与资源分配。文中建立了大小—制约分配模型，并用此模型预测了与觅养生长格局有关的资源分配。这一研究深刻地揭示了较为动物种群搜索途径复杂得多的无性系植物种群的觅养行为。

| Abstract: | Based on variation of growth parameters and development parameters, foraging growth pattern and resource allocation of clonal Leymus chinensis population were studied. Relationships between the law of resource allocation and microhabitat quality of the population were analyzcd in terms of mathematic methods. Foraging behaviour of this population was also discussed. The results showed that foraging growth parttern of resource alloation could be described using allocaion function models in which ψ=0.5, μ=l.0,Tr=7, and Ts = 2. |
