　　基于衛(wèi)星影像的土地利用／土地覆被研究（LULCC）需要大量資金、技術(shù)人力以及高精度影像分辨率的支持,對于發(fā)展中國家來說（如加納）,利用其有限的人力、物力等資源進行LULCC研究無疑是個挑戰(zhàn)。目前,加納的研究區(qū)域主要集中在加納南部地區(qū),尚未涉及北部區(qū)域的研究,而本研究是基于RS與GIS技術(shù),對加納北部區(qū)域的瓦城（Wa）和Nadowli地區(qū)中礦產(chǎn)相關(guān)區(qū)域土地利用/土地覆被進行動態(tài)評估。通過采用1991,2000及2014年這三個不同時相遙感影像數(shù)據(jù)來量化該區(qū)土地利用／土地覆被變化,以最大似然分類算法對加納北部礦產(chǎn)密集區(qū)進行LULCC研究。研究過程中,利用空間社會關(guān)聯(lián)化法將遙感影像和社會經(jīng)濟數(shù)據(jù)的結(jié)合,采用用地演變模型和土地利用綜合指數(shù)來描述土地利用變化的特點。用地演變模型運行結(jié)果表示草地向裸地和居民地變化,并且開發(fā)性草地和封閉性草地分別從50.80%減少至36.5%,27.80%減少至22.67%,與此同時,裸地和居民地面積增長。瓦城東部區(qū)域的2014時相影像分類準確率和Kappa系數(shù)分別為83.20%和0.761。植被覆蓋指數(shù)NDVI)用于顯示植物健康狀態(tài),NDVI指數(shù)由0.48減少至0...
