基于多时相ENVISAT ASAR的鄱阳湖水面覆盖信息提取及其应用研究
Extraction and Application of Water Coverage Data of poyang Lake Base on Multi-temporal ENVISAT ASAR
摘要
Abstract
Based on the ENV1SAT ASAR data, taking into account the ehatacteristic of synthetic aperture side scan and great differences of the topography,climate conditions and hydrological conditiond in Poyang Lake,the cariations of Poyang Lake water coverage in 2009 were extracted and analyzed by the parition threshold method,and then the high-resolution satellite data HJ-IAwas adopted to verify ASAR mage water information extraction results,inspection results proved the efftiveness od partitioned threshold method.Finally,the wetland atea of Poyang Lake basin which water level was above 17 meters(Wusong elevation)and continuously submerged for no more than 70 days was calculated, which provided scientific reference for the govemment to plan the planting area,implement compensation policy and alleviate flood loss.关键词
