MODIS論文：長江中游洪澇災(zāi)害的MODIS時序監(jiān)測與分析【中文摘要】近年來,氣候與環(huán)境變化日益加劇,自然災(zāi)害的發(fā)生日趨頻繁,洪澇災(zāi)害已成為我國發(fā)生最頻繁的自然災(zāi)害之一,特別是長江中游地區(qū),幾乎每年都有發(fā)生。衛(wèi)星遙感憑借其監(jiān)測范圍廣、速度快、成本低,且便于進行長期動態(tài)監(jiān)測的特點而一躍取代傳統(tǒng)的實地調(diào)查方法成為獲取洪澇災(zāi)害時空分布信息的有效手段。MODIS(Moderate-resolution Imaging Spectroradiometer)數(shù)據(jù)以其較高的時間分辨率、空間分辨率和光譜分辨率、覆蓋范圍廣、輻射校正準確、且可以免費獲取的優(yōu)勢而成為洪澇災(zāi)害監(jiān)測的一種優(yōu)秀的數(shù)據(jù)源。本論文利用MODIS數(shù)據(jù)提取淹沒水體的時間序列變化,以監(jiān)測長江中游在2000-2010年間的洪澇災(zāi)害,并對洪災(zāi)的淹沒水深和災(zāi)后土地利用以及人口方面的受損情況進行評估,是綜合評估分析近十年洪澇災(zāi)害的時空特征。論文首先探討了衛(wèi)星遙感水體監(jiān)測的理論基礎(chǔ)和方法,從水體的波譜特征入手,針對TM(Thematic Mapper)影像、MODIS影像、NOAA/AVHRR(National Oceaongraphic Atmospheric Administrative/Advanced Very High.【英文摘要】In recent years, with the growing changes of climate and environment, natural disasters have become more and more frequent. Flood disaster is one of the natural disasters with the high frequency in our country, especially in the middle reaches of the Yangtze River where the flood happened almost every year. The satellite data has the advantages of wide coverage, speed monitoring, low cost and is easy to be carried for the long-term dynamic monitoring. Therefore, remote sensing has replaced the traditional m.【關(guān)鍵詞】MODIS 洪澇災(zāi)害 遙感 長江中游 淹沒水深 災(zāi)后評價【英文關(guān)鍵詞】MODIS Flood Disaster Remote Sensing Middle Reaches of Yangtze River Emerged Depth Disaster Assessment【目錄】長江中游洪澇災(zāi)害的MODIS時序監(jiān)測與分析中文摘要6-8Abstract8-91 緒論10-181.1 研究目的和意義10-121.2 國內(nèi)外研究概況12-151.3 研究內(nèi)容和成果15-161.4 論文結(jié)構(gòu)161.5 本章小結(jié)16-182 衛(wèi)星遙感水體監(jiān)測理論基礎(chǔ)和方法18-232.1 水體的波譜特征182.2 水體的遙感監(jiān)測方法及模型18-222.3 本章小結(jié)22-233 研究區(qū)概況與研究數(shù)據(jù)23-293.1 研究區(qū)概況23-243.2 研究數(shù)據(jù)24-263.3 數(shù)據(jù)處理26-283.4 本章小結(jié)28-294 洪澇災(zāi)害遙感監(jiān)測29-374.1 洪澇災(zāi)害遙感監(jiān)測原理294.2 洪澇災(zāi)害遙感監(jiān)測結(jié)果29-314.3 長江中游洪澇災(zāi)害分析31-364.4 本章小結(jié)36-375 洪澇災(zāi)害淹沒水深分析37-495.1 洪澇災(zāi)害淹沒水深監(jiān)測原理37-385.2 洪澇災(zāi)害淹沒水深監(jiān)測結(jié)果及分析38-475.3 本章小結(jié)47-496 洪澇災(zāi)害災(zāi)后分析49-716.1 洪澇災(zāi)害災(zāi)后損失評價方法49-506.2 洪澇災(zāi)害災(zāi)后損失的綜合評價50-536.3 洪澇災(zāi)害災(zāi)后損失評價縣市級53
