几种卫星系统监测林火技术的比较与应用-世界林业研究

舒立福王明玉赵凤君李红田晓瑞(,100091):卫星遥感方法作为灾害监测手段,在时间分辩率和宏观性方面具有优势目前用于我国森林火灾监测的主要是美国的NOAA系列气象卫星,此外,我国的风云系列气象卫星和美国的EOS卫星也开始应用于林火监测NOAA和风云系列气象卫星为森林火灾的监测提供了可靠稳定的服务,但因分辩率低给森林火灾信息的提取监测带来一定困难应用美国EOS卫星进行林火监测,可以提高监测精度和准确度,为火灾的扑救提供更多更可靠和更细致的监测成果,将卫星遥感技术用于森林火灾监测,涉及估算火烧面积火烧强度火灾后生态环境监测等诸多领域:林火,卫星遥感,NOAA,FY卫星,EOSMODIS:S762:A:1001-4241(2005)05-0049-05ComparisonandApplicationofSatellitesinForestFireMonitoringShuLifuWangMingyuZhaoFengjunLiHongTianXiaorui(ResearchInstituteofForestEcology,EnvironmentandProtection,ChineseAcademyofForestry,Beijing100091,China)Abstract:Remotesensinghastheadvantageoftemporalresolutionandlargescaleindisastermonitor-ing.InChina,themainsatellitesusedforforestfiremonitoringareNOAAsatellites,FYserialsmeter-ologicalsatellitesandEOSsatellites.NOAAandFYsatellitescanmonitorthehotspotaccurately,butitisdifficulttoextractsomeinformationforlowresolution.EOSsatellitescanmonitorthehotspotmoreaccuratelyandcanextractmoreinformationforfirefighting.Inforestfiresmonitoringmanyfieldssuchasburnedareaassessment,fireintensityevaluation,ecologicalenvironmentmonitoringafterfiresarein-cludedKeywords:forestfires,remotesensing,NOAA,FYsatellites,EOSMODIS,,,,,,,,,,[1],,,205080,,,,[2],,198756,:2005-03-04:(No30371170);186Vol18No6200512WorldForestryResearchDec,2005[3]1NOAAAVHRRNOAAAVHRR(TheAdvancedVeryHighRes-olutionRadiometer)NOSS,NOAAAVHRR,11km,,01hm24,,NOAAAVHRR3,AVHRR54,,2700km,,,12hNOAA,24h4,,,,[4]AVHRR5(),()1NOAAAVHRR12,LANDSATTM5733(355~393um),;45,AVHRR,1NOAAAVHRR(m)(mrad)1058~0681392072~1101413355~39515241030~113014151150~1250130NOAA,,,,,,[5,6]2(FY),,,211m,950kg,2105~10,NOAA5018(2),810,60min300min,,44km1020min11km,FY,,2FY-1C(m)1058~0682084~0893355~3954103~1135115~1256158~1647043~0488048~0539053~058100900~0965FY-1c,,,,FY;FY-1c10,1,2,34,,3,45,FY-1c,,,:,;,,;,,3EOSMODIS2080,EOS(TheEarthObservingSystem)MODIS(Moder-ateResolutionImagingSpectroradiometer),,,,EOS,EOS,[7]EOS,,51EOSAM-1199912,4EOSAM-2EOSPM-2,15705km,2330km,24h2MODISEOS,36,516:7(720~25)250~500m,,500~1000mEOSMODIS250m,,;250m,,721m500m,6~1000K,300K,20~2563~5m,1000m,,720~25,EOS,,;;[8]MODIS,NOAA,3EOSMODIS(m)(m)1062~0672502084~087250,6162~165500,7210~213500,20366~3841000,21392~3981000,22392~3981000,23402~4081000,24443~4491000,25448~4541000,311078~11281000321177~122710004(1),,(2)NOAAVHRR,,,(3)FY,,FY5218,,(4)EOS,,NOAA,,(5)NOAA,FYNOAA,EOS,,1KaufmannYJ,TuckerCJ,FungIRemotesensingofbiomassburninginthetropicsJGeophysicalResearch,1990,95(D7):9927~99392,:,199921~273CahoonJrDR,StocksBJ,LevineJS,etalSatelliteanalysisofthesevere1987forestfiresinnorthernChinaandsoutbeasternSiber-riaJournalofGeophysicalResearch,1994,99(D9):18627~186384LopezS,GonzalezF,LLopR,etalAnevaluationoftheutilityofNOAAAVHRRimagesformonitoringforestfireriskinSpainIntern-ationalJournalofReoteSensing,1991,12(9):1841~18525,,3S,1999,8(1):12~186KasischkeES,FrenchNHF,HarrellPA,etalMonitoringofwildriersinborealforestsusingAVHRRNDVIcompositeimageda-taRemoteSensingofEnvironment,1993,45:61~717,MODIS:,20018LimKH,KwohLlewSCDevelopmentofaMODISDataReceptionSystemforRegionalEnvironmentalMonitoringinSoutheastAsia22ndAsianConferenceonRemoteSensing,Singapore,20012006()()CAJ-CD3S(),,,,,:ISSN1671-3168,CN53-1172S,800,112,6000,,:289:650051:::029101040002050:[phone];3332538:[phone]E-mail:ynfip@vip163com:http:lydcghperiodicalsnetcn536:
