摘　　要：建立了两集合种群物种对两种线性增长资源的竞争模型,并模拟了不同斑块上利用两种有限资源的两个消费者物种在不同迁徙率和资源增长率下的竞争机制.A model of two metapopulation species and two exponential growth resources were set up. In the meanwhile, the competitive mechanism of the two consumer populations was simulated by using two forms of limiting resources at different dispersal and resources growth rate over distinct patches.
