With the rapid development of economy, urbanization expands extensively and land use in urban and suburban areas changes dramatically. To achieve sustainable development, it is important to take a full consideration of environmental factors during urbanization process. Focused on Zhengzhou, Kaifeng and Zhongmu, this study investigates the change in land coverage and the characteristics of urbanization of city agglomerations in the middle and lower reaches of Yellow River, based on Landsat data and the survey of local land use. The map of land coverage classification will be constructed and the current situation of land coverage in targeted areas analyzed. On this basis, the change of built-up area will be studied using the Kernel Density Presumption method, and the influence of traffic infrastructure analyzed, leading to the elucidation of the characteristic of urbanization.
