英文摘要： The studied areas is located in Dafeng city which is in the core area of coastal development region in Jiangsu province and is belonged to one of high-potential development region in China coastal zone. In the study, the method of remote sensing geo-cognition on ecological land is to be developed. The methods of knowledge-oriented intelligent identification and extraction of ecological land information are to be studied based on multi-source remote sensing data. The remote sensing estimation methods of vegetation biomass and carbon are also to be studues based on hyperspectral image and LIDAR data and multi-source data. The spatial and temporal changes in ecological land and their driving forces are to be discovered. The key techniques for grid management on the information of ecological land based on the multi-scale information based on the mode of grid-administrative unit are to be developed. The precision method of ecological management and protection is to be proposed in the typical region. This study will contribute to the development of land change science research and the theory and method of remote sensing monitoring on land resource and ecological system, and will supply technical support for the change of the land resource management mode of “quantity control and management” & “quality management” & ecological management and protection”.
