　　土地利用和土地覆蓋（LULC）對(duì)于更好地了解人類與環(huán)境相互作用、增加對(duì)氣候和環(huán)境系統(tǒng)相互影響的理解十分重要,使實(shí)現(xiàn)合理的環(huán)境管理措施成為可能。LULC是動(dòng)態(tài)變化的,它的變化具有重要的環(huán)境和社會(huì)經(jīng)濟(jì)影響。氣候變化及其多方面的、多尺度的影響帶來(lái)了巨大的挑戰(zhàn)。本文將多種驅(qū)動(dòng)因素考慮在內(nèi),對(duì)孟加拉國(guó)東南部地區(qū)的土地利用時(shí)空格局、動(dòng)態(tài)變化進(jìn)行了系統(tǒng)的監(jiān)測(cè),對(duì)未來(lái)的情形進(jìn)行了模擬。因此,該研究重點(diǎn)突出四個(gè)相互關(guān)聯(lián)的科學(xué)問(wèn)題:1)比較多種土地覆蓋產(chǎn)品并識(shí)別不一致水平較低產(chǎn)品;2)評(píng)估土地利用/覆蓋變化（LUCC）的當(dāng)前趨勢(shì);3)外部變量對(duì)地表動(dòng)態(tài)影響的地理空間關(guān)系;4)在可持續(xù)的土地管理和規(guī)劃背景下,對(duì)未來(lái)土地利用進(jìn)行多情景模擬和預(yù)測(cè)。高質(zhì)量的土地覆蓋產(chǎn)品對(duì)于監(jiān)測(cè)和分析LUCC以及全球環(huán)境變化研究具有重要意義。因此,本研究主要利用IGBP-17、IGBP-9、IPCC-5和TC（植被、濕地和其他地類）的通用分類系統(tǒng),對(duì)四種土地覆蓋產(chǎn)品中面積和空間不一致性進(jìn)行了分析,將高時(shí)間分辨率和多種方式驗(yàn)證的MODISLC、GlobeLand30、FROM-GLC和Landsat TM/ETM+等產(chǎn)品作為研究數(shù)據(jù)...
