In urbanization progress, population changes are the main factor to understand all other changes, especially land use changes. Through the study on population urbanization and its influence on land use, we can master the whole characters of urbanization development in certain region. And this will be important to urbanization research and the discussion of connection between population and land.

The study shows:(1) In Suizhou city, the urban level is at the second stage (>30%) and the urbanization develops in the same rate as the industrialization.(2) In urbanization progress, the urban population increases rapidly but total population has begun to decrease. And the population distributes evenly in the whole region while also concentrating in the center city to some extent.(3) Relative to the second stage of industrialization in Suizhou city, the proportion of agricultural employment is higher than normal. And this results from its natural conditions.(4) In Suizhou city, population changes influence on land use mainly through the expansion of cities using agricultural land, especially cultivated land.
