  稻作農(nóng)業(yè)對諸如溫室氣體排放、糧食安全、水資源利用和疾病傳播等問題有重要影響。盡管水稻分布制圖方法和應(yīng)用不斷改進和深化,但現(xiàn)有的大區(qū)域水稻識別通常精度較低且數(shù)據(jù)稀缺。本論文旨在推進遙感衛(wèi)星數(shù)據(jù)在水稻分布制圖方面的應(yīng)用,論文通過建立適合海量數(shù)據(jù)分析的有效方法,并在典型水稻種植地區(qū)進行精度驗證,主要包括以下幾個方面:(1)采用面向?qū)ο蟮挠跋穹治龇椒ǎ∣BIA)研究了物候?qū)λ痉植贾茍D的影響。利用高分辨率多光譜遙感數(shù)據(jù)結(jié)合作物物候信息,對水稻進行了精細分類。利用遙感提取的農(nóng)作物物候的差異捕捉不同作物生長過程的動態(tài)特征,并利用高空間分辨率的多光譜數(shù)據(jù)探測不同地區(qū)農(nóng)作物的空間變異模式。論文利用MODIS20NDVI時間序列數(shù)據(jù)提取作物物候信息,而中國環(huán)境減災(zāi)小衛(wèi)星星座(HJ-1A/B)數(shù)據(jù)則主要用于水稻種植區(qū)的提取。論文的對比研究結(jié)果表明,將多光譜數(shù)據(jù)與作物物候信息結(jié)合能夠顯著提高水稻的分類精度。(2)論文探索比較了從中低分辨率遙感數(shù)據(jù)中提取的33種反映作物生長過程的物候參數(shù)對基于高分辨率遙感數(shù)據(jù)開展水稻分類識別精度的提升效果。研究結(jié)果表明,運用優(yōu)選的反映作物生長過程的物候特征參數(shù)顯著地提高了由單...
