摘　　要：用格子Boltzmann方法研究描述疟疾病疟蚊系统的具有迁移性质的Ross-Macdonald方程,先构建Ross-Macdonald方程的格子Boltzmann模型,再用该模型对疟疾病疟蚊系统进行数值模拟,并将格子Boltzmann方法与有限差分方法的数值解进行比较.结果表明,该方法可用于模拟疟疾病疟蚊系统.We used the lattice Boltzmann method to study the Ro ss-Macdonald equations with drift property which described the Malaria-Malaria mosq uito system.We first constructed a lattice Boltzmann model for the Ross-Macdon ald equations,then used this model to simulate the Malaria-Malaria mosquit o system,and compared the numerical solutions of the lattice Boltzmann method w ith those of the finite difference method.The results show that this method can be used to simulate the Malaria-Malaria mosquito system.
