Based on the multi-source remote sensing data, GIS ancillary data and statistical data, this paper revealed the spatial-temporal evolution and uncoordinated development characteristics of land-population urbanization at the county level in Bohai Rim region in the past 20 years using the methods of GIS spatial analysis and index analysis. The research results showed as follows; Firstly, the land and population urbanization levels of the counties both were mainly at the low level, but the counties with medium to high land urbanization level were mainly distributed around the municipal districts, while the counties with medium to high population urbanization level were mainly continuously distributed in the developed areas. Secondly, the land and population urbanization levels both presented a significant growth trend, but the counties with high growth of land urbanization level were mainly distributed in the coastal zones and the capital cities, while the counties with high growth of population urbanization level were mainly distributed in Hebei province. Thirdly, about 94.56% of the counties presented uncoordinated development between land and population urbanization and their uncoordinated grades were mainly mild disorder, most of the population urbanization level belonged to lag types. Fourthly, the uncoordinated level presented as cyclical fluctuation and spirally rising trend, and the proportion of severe uncoordinated development had a small increase, while the proportion of lag-type population urbanization had a marked increase. These findings could provide references for optimizing the pattern of urbanization and promoting the coordinated development of land-population urbanization.
