Abstract: For two different types of cities of Hainan Province, the urban expansion of Haikou City and Sanya City during 2000-2015 was analysed and monitored by the combination of the pixel unmixing model and decision tree method. Furthermore, we simulated the distribution pattern of the urban land usage in 2020 based on CLUE-S model, and compared the differences of urban development between the two cities. Simulation results show that Haikou City and Sanya City will have substantial expansions in 15 years, especialy Sanya City will be expended 3.4 times. Experiments show that the combination of the pixels unmixing model and CLUE-S model can provide more detail information on the urban development process, and is helpful to urban planning and land resources decisionmaking.

Key words: pixel un-mixing model, CLUE-S model, urban expansion, simulation, remote sensing monitoring
