According to the relevant data about the land resources and population in Liaocheng City from 1999 to 2008, by using the research method of bearing capacity of natural resources, the thesis analyzes the relationship between natural resources and dynamic change of population in Liaocheng City. The results show that the farmland tends to diminish on the whole, and forests, garden land, urban-rural settlements and land for enterprises and mining increase slowly.
