This paper reviewed the progress of near-shore habitat satellite remote sensing (RS) monitoring and the studies of near-shore ecology impacted by habitat changes. It summarized near-shore habitat geographical, biological, physical and chemical factors which may critically affect marine living organism at the beginning, and then give the main arithmetic by which the habitat factors might be monitored with the recent on duty satellites sensors. It also reviewed the common methods which were used to detect red tide, green algae blooming, and biodiversity. Finally, this paper provides some case studies, such as the study of habitat geographical changes (determined by sea reclamation) impact on biodiversity, and the monitoring of red tide and giant green algae blooming and the distribution of coral reef and mangrove forest, for relevant scientist references.
