摘要 利用偶对近似方法研究了空间结构下雌核发育及其依附的有性生殖种群的迁移对系统种群空间分布的影响.数值模拟的结果表明:雌核发育和有性生殖种群的迁移均有利于雌核发育种群数量的增加,同时均抑制了有性生殖种群数量,但是,其影响强度存在明显的不对称性.相比有性生殖而言,雌核发育的迁移对系统的影响十分明显.和有性生殖的迁移相比较,雌核发育的迁移对整个系统的空间分布影响也更显著.这些结果对进行雌核发育物种培育,提高经济效益有着重要的现实意义. The pair-approximation model was used to investigate the effect of migration on the spatial structure of genogenesis system. The results of a numerical simulation demonstrated that both genogenesis and the migration of dependent sexual species were conducive to the increase of genogenesis of species but inhibited sexual species. However, the impact strength was obviously asymmetrical： compared with the migration of sexual reproduction, migration of genogenesis was very obvious in the system; compared with the effect of the migration of sexual reproduction, that of the migration of genogenesis was more significant. These results can help foster genogenetics and enhance economic efficiency, which are of great significance in real practice.
