東北地區(qū)水環(huán)境參數(shù)遙感監(jiān)測與反演研究進(jìn)展
東北地理所地理景觀遙感學(xué)科組在東北地區(qū)內(nèi)陸湖泊水質(zhì)參數(shù)遙感反演、地表實際蒸散遙感估算等方面取得系列研究進(jìn)展,相關(guān)研究成果發(fā)表在遙感、環(huán)境科學(xué)和生態(tài)學(xué)領(lǐng)域的國際主流學(xué)術(shù)期刊。
學(xué)科組應(yīng)用經(jīng)驗?zāi)P汀虢馕瞿P汀A-PLS智能算法,對東北地區(qū)重要內(nèi)陸湖泊和城市水源地的葉綠素含量、總懸浮物含量等水質(zhì)參數(shù)進(jìn)行了遙感監(jiān)測與空間反演[1-4],這些研究結(jié)果為東北地區(qū)內(nèi)陸水體富營養(yǎng)化與藍(lán)藻爆發(fā)的實時遙感監(jiān)測提供理論與技術(shù)支撐,同時也為其他地區(qū)湖泊富營養(yǎng)化遙感監(jiān)測與動態(tài)分析提供了技術(shù)支撐。課題組深入開展內(nèi)陸水體固有光學(xué)特性研究,為生物光學(xué)模型的實現(xiàn)奠定基礎(chǔ)[5]。基于SEBAL模型與MODIS遙感數(shù)據(jù)產(chǎn)品,對松嫩平原地表實際蒸散量ET進(jìn)行估算,為松嫩平原農(nóng)業(yè)生產(chǎn)水分管理提供依據(jù)[6],可為農(nóng)業(yè)水分利用效率空間決策提供可視化依據(jù)。
以上研究工作得到中國科學(xué)院知識創(chuàng)新工程重要方向項目(KZCX2-YW-340)、(KZCX2-YW-QN305)、國家自然科學(xué)基金項目(41171293)的資助。
