Coastal wetlands as a unique ecosystems with high productivity and abundant biology diversity，has many important resource values，ecological values，economic values and scientific research values.Due to the multi\|temporal，multi\|platform，macroscopic，objective，informative，real\|time，highly effective，comparable and so on，so the remote sensing technology has been gradually approved and widely promoted in coastal wetland research in the past three decades.Current status of coastal wetland research based on remote sensing technique in China was systematically discussed from multiple aspects，including remote sensing data sources，theories and methods，and the application of remote sensing technology to Chinese coastal wetland is reviewed from the aspects of coastal wetland resource investigation and management，landscape pattern and dynamic change，ecological environment monitoring，ecosystem quality and service evaluation.This paper also points out some shortcomings existed in Chinese coastal wetland research by remote sensing technology include the spatial and temporal distributions of the study area is uneven and dominated by small and medium scale，lack of interdisciplinary comprehensive research，focus on theoretical research and ignore application intelligent application of remote sensing technology，information sharing ability is poor，the improve of interpretation accuracy is difficulties.Related research prospects should be to carry out such as monitoring and mapping on all scale，strengthen the multidisciplinary collaboration，strengthen the comprehensive and comparative study，establish a unified classification system of coastal wetland based on remote sensing and the national coastal wetland information system，emphasis on the development of new remote sensing technology and fusion of multi\|source data，emphasis on the use of new methods and new models.
