Multi-Polarization ASAR Backscattering from Herbaceous Wetlands in Poyang Lake Region, China
Wetlands are one of the most important ecosystems on Earth. There is an urgent need to quantify the biophysical parameters (e.g., plant height, aboveground biomass) and map total remaining areas of wetlands in order to evaluate the ecological status of wetlands. In this study, Environmental Satellite/Advanced Synthetic Aperture Radar (ENVISAT/ASAR) dual-polarization C-band data acquired in 2005...
متن کاملAbsorption and backscattering coefficients and their relations to water constituents of Poyang Lake, China.
The measurement and analysis of inherent optical properties (IOPs) of the main water constituents are necessary for remote-sensing-based water quality estimation and other ecological studies of lakes. This study aimed to measure and analyze the absorption and backscattering coefficients of the main water constituents and, further, to analyze their relations to the water constituent concentratio...
متن کاملChanges in rice cropping systems in the Poyang Lake Region, China during 2004–2010
Rice cropping systems not only characterize comprehensive utilization intensity of agricultural resources but also serve as the basis to enhance the provision services of agro-ecosystems. Yet, it is always affected by external factors, like agricultural policies. Since 2004, seven consecutive No.1 Central Documents issued by the Central Government have focused on agricultural development in Chi...

متن کاملNeural Network-based Analytical Model for Biomass Estimation in Poyang Lake Wetland Using Envisat Asar Data
Poyang Lake is the largest freshwater lake in China with an area of about 3,000 km2. Its wetland ecosystem has a significant impact on China’ s environment change. Traditional way to monitor biomass change on this area is to use linear or nonlinear model from TM/ETM data. In this paper we discuss the neural network algorithms(NNA) to retrieve wetland biomass from multipolarization(HH and VV) ba...
