The purpose of this paper is to summarize the states quo of land use change survey data application from the aspects of temporal distribution and subjects’ distribution of current studies, and further to give an outlook of its promotion direction and application foreground. The methodology is using conditional retrieve and bibliometric method to analyze the temporal and discipline distribution of relevant literatures, and draw a presentation of the application status and pros and cons of the land use change data（LUCD） according to the classification results. The application status of LUCD temporally experienced its infancy stage, exploration stage, growth stage, and bottleneck stage. The application cases majorly focused on land sciences, and also rural issues, environment and ecology, socio-economic development and the transport sector. The paper concludes that efforts should be made to improve the frequency data updating, refine the land classification, record the reasons on land use change and the spatial information, enhance the transparency and availability of land pollution data for a boarder and deeper application the LUCD.
