摘　　要：土地利用及景观格局变化对城市的发展具有重要意义,为全面了解槟城1990年~2018年土地利用及景观格局变化情况,利用指数分类法和纹理特征判断相结合的方法对槟城1990年的TM和2018年的OLI遥感影像进行土地利用分类,依据转移矩阵和景观指数对槟城土地利用及景观格局变化进行分析。结果表明:近28年来,槟城土地利用发生明显变化,其中建设用地面积增加138.63km^2,种植园以每年1.56%的速率减少,主要转化为建设用地和林地;林地和水体破碎度增高,耕地、种植园、建设用地、未利用的破碎度降低;林地和建设用地最大斑块指数增高,耕地和种植园降低,水体和未利用地则变化微小。Land use and landscape pattern change are of great significance to the development of city,to fully understand the changes of land use and landscape pattern in Penang from1990 to 2018,using the index of judging method of combining the taxonomy and texture feature of Penang TM in 1990 and 2018 OLI to land use remote sensing image classification,on the basis of transfer matrix and landscape index to Penang land use and landscape pattern change were analyzed.The results show that in the past 28 years,Penang has undergone significant changes in land use,including an increase of 138.63 km^2 in the area of construction land and a decrease of 1.56% per year in plantations,mainly converted to construction land and forest land.The fragmentation degree of forestland and water increased,while the fragmentation degree of cultivated land,plantation,construction land and unused land decreased.The maximum patch index of forestland and construction land increased,cultivated land and plantation decreased,and water and unused land changed little.
