【摘要】：水稻延遲型冷害大范圍準(zhǔn)確的同步跟蹤監(jiān)測(cè),可為提高稻米品質(zhì)和產(chǎn)量提供幫助。在明確東北地區(qū)水稻種植區(qū)域和水稻低溫冷害年的基礎(chǔ)上,基于MODIS MOD13A2數(shù)據(jù)產(chǎn)品劃分了東北地區(qū)水稻各發(fā)育普遍期植被指數(shù)判識(shí)指標(biāo)的參考范圍,構(gòu)建了基于地理信息的水稻發(fā)育期模型,在此基礎(chǔ)上制作了水稻靜態(tài)發(fā)育期空間分布圖,并以2009年5月24日和8月7日為例開(kāi)展了東北地區(qū)水稻延遲型冷害動(dòng)態(tài)監(jiān)測(cè)的應(yīng)用研究。結(jié)果表明:東北三省發(fā)生較大范圍水稻延遲型冷害的年份有2002年、2003年、2008年和2009年,其中黑龍江省是水稻延遲型冷害的重災(zāi)區(qū);EVI在水稻發(fā)育期判識(shí)中較NDVI更具優(yōu)勢(shì);利用經(jīng)度、緯度和海拔高度與日序的相關(guān)關(guān)系構(gòu)建水稻發(fā)育期模型,推算無(wú)觀測(cè)地區(qū)的發(fā)育期具有一定的可行性;在同一時(shí)間東北三省各地的水稻發(fā)育期分布推算結(jié)果的基礎(chǔ)上,實(shí)現(xiàn)了2009年5月24日和8月7日東北地區(qū)水稻延遲型冷害動(dòng)態(tài)監(jiān)測(cè),所得監(jiān)測(cè)結(jié)果與2009年農(nóng)業(yè)氣象觀測(cè)記錄在時(shí)間和空間上有很好的一致性,監(jiān)測(cè)結(jié)果正確。
[Abstract]:In order to improve the quality and yield of rice, the delay chilling damage can be monitored synchronously and accurately in a wide range. On the basis of defining the region of rice cultivation and the year of low temperature chilling injury of rice in Northeast China, Based on the MODIS MOD13A2 data product, the reference range of the identification index of the vegetation index in different stages of rice development in Northeast China was divided, and the model of rice development period based on geographic information was constructed. On this basis, the spatial distribution map of rice static development period was made. Taking May 24th 2009 and August 7th as examples, the dynamic monitoring of delayed chilling injury of rice in Northeast China was studied. The results showed that the years of large-scale delayed chilling injury occurred in Northeast China were 2002, 2002, #date鈪，
