ABSTRACT
Wetlands are essential natural resources for human beings in terms of providing multiple ecosystem services. Remote sensing is critically important in monitoring wetlands for protecting the related environments and ecosystems. This chapter summarizes remote sensing applications in wetland monitoring and introduces a case of Poyang Lake, the largest freshwater lake in China, in terms of monitoring of variation of natural wetlands corresponding to the changing water levels. The mapping results reveal that the landscape of Poyang Lake wetland presents dramatic seasonal variation. Finer spatial resolution multitemporal Landsat-8 data are much appreciated for monitoring of the wetlands that are routinely affected by the dynamics of water levels of the Poyang Lake. The data process and analysis approaches are applicable to most of the situations for monitoring of the changing environment, in particular, for the subjects of inland water and wetland monitoring.
