東北地區水環境參數遙感監測與反演研究進展
東北地理所地理景觀遙感學科組在東北地區內陸湖泊水質參數遙感反演、地表實際蒸散遙感估算等方面取得系列研究進展，相關研究成果發表在遙感、環境科學和生態學領域的國際主流學術期刊。
學科組應用經驗模型、半解析模型、GA-PLS智能算法，對東北地區重要內陸湖泊和城市水源地的葉綠素含量、總懸浮物含量等水質參數進行了遙感監測與空間反演[1-4]，這些研究結果為東北地區內陸水體富營養化與藍藻爆發的實時遙感監測提供理論與技術支撐，同時也為其他地區湖泊富營養化遙感監測與動態分析提供了技術支撐。課題組深入開展內陸水體固有光學特性研究，為生物光學模型的實現奠定基礎[5]。基于SEBAL模型與MODIS遙感數據產品，對松嫩平原地表實際蒸散量ET進行估算，為松嫩平原農業生產水分管理提供依據[6]，可為農業水分利用效率空間決策提供可視化依據。
以上研究工作得到中國科學院知識創新工程重要方向項目(KZCX2-YW-340)、（KZCX2-YW-QN305）、國家自然科學基金項目（41171293）的資助。
