土地覆蓋是一個非常重要的跨領域環(huán)境變量,它是水文、氣候、土壤、生物多樣性、自然災害和生物地球化學循環(huán)等不同環(huán)境問題的中心。生態(tài)系統(tǒng)服務的可用性和可持續(xù)性,其作為人類的生存基礎也正日益受到來自土地變化研究的關注。因此,一些國家和國際項目對土地覆蓋變化（LCC）信息給予了高度重視。此外,無論是基于光譜還是基于類別,土地覆蓋監(jiān)測對于機構制定和執(zhí)行環(huán)境政策或檢查現(xiàn)有政策的影響都至關重要。由于平潭島內有限的空間,因此在快速發(fā)展經濟的同時,引起了LCC和濱海圍墾現(xiàn)象。值得注意的是,自從成立平潭綜合實驗區(qū)并且確定國際旅游島和自由貿易區(qū)的總體經濟發(fā)展規(guī)劃以來,其社會經濟的發(fā)展更加快速。然而,截至目前,對于平潭島土地覆蓋的具體變化情況、地塊布局情況以及驅動因子方面的研究仍然較少。因此,本文對平潭島土地覆蓋斑塊的空間組成及配置、驅動因素以及其對平潭島生態(tài)系統(tǒng)服務的影響進行綜合量化研究,研究主要包括四個階段,分別為1984-1996（第一階段）、1996-2007（第二階段）、2007-2017（第三階段）和1984-2017（整個階段）。本文利用遙感和地理信息系統(tǒng)（GIS）技術,分別獲得平潭島1984年（...
