Wetland information extraction and ecological sensitivity evaluation method based on microwave remote sensing technology and optical remote sensing technology

The invention discloses a wetland information extraction and ecological sensitivity evaluation method based on a microwave remote sensing technology and an optical remote sensing technology. The method overcomes defects existing in the prior art that wetland information extraction is carried out based on optical remote sensing data. According to the method, information extraction of different wetland types, such as a marsh wetland, an under-forest wetland and a water area, is carried out according to optical remote sensing data features and microwave remote sensing data features, wetland distribution, wetland soil moisture, wetland water systems and other information are recognized, a wetland ecological sensitivity evaluation model is established, and highway side buffer zone wetland ecological sensitivity evaluation is carried out. Through the method, extraction precision is improved, and the extraction method is easier, more suitable for utilization and popularization and quite suitable for wetland informat
