Abstract Ecological environment degradation and sustainable development of wetland has become the focus of the current wetland research, it is necessary to study on wetlands monitoring dynamic changes.The study investigated wetland type and dynamic changes in Hainan Dongzhai Reserve based on three high resolution remote sensing images recorded in 2002, 2008 and 2013, respectively. The results indicated that there was little change in wetland types during 2002 to 2013. Coastal water, mangrove and culture pond were the main types of wetland in this area. The area of natural wetland trended to decline, while the total area and the numbers of individual wetland to increase. The most increased wetland types were the area of tidal creek in proportion and the culture pond in individual numbers. The changes were discovered frequently in edges of landward edge in which human activities were extensive.In aspect of the area of wetland, the dynamic degrees of the wetland changes during 2002 to 2013 in this area were small. The types of coastal water mangrove and tidal creek mainly trended to be stable. While concentrated in the types of reservoir, sandy tidal wetlands and culture pond, the dynamic degrees were big, and they were the type of wetland with swift changes.
