　　土地利用和土地覆蓋（LULC）對于更好地了解人類與環(huán)境相互作用、增加對氣候和環(huán)境系統(tǒng)相互影響的理解十分重要,使實現(xiàn)合理的環(huán)境管理措施成為可能。LULC是動態(tài)變化的,它的變化具有重要的環(huán)境和社會經濟影響。氣候變化及其多方面的、多尺度的影響帶來了巨大的挑戰(zhàn)。本文將多種驅動因素考慮在內,對孟加拉國東南部地區(qū)的土地利用時空格局、動態(tài)變化進行了系統(tǒng)的監(jiān)測,對未來的情形進行了模擬。因此,該研究重點突出四個相互關聯(lián)的科學問題:1)比較多種土地覆蓋產品并識別不一致水平較低產品;2)評估土地利用/覆蓋變化（LUCC）的當前趨勢;3)外部變量對地表動態(tài)影響的地理空間關系;4)在可持續(xù)的土地管理和規(guī)劃背景下,對未來土地利用進行多情景模擬和預測。高質量的土地覆蓋產品對于監(jiān)測和分析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),對四種土地覆蓋產品中面積和空間不一致性進行了分析,將高時間分辨率和多種方式驗證的MODISLC、GlobeLand30、FROM-GLC和Landsat TM/ETM+等產品作為研究數(shù)據...
