摘　　要：城市化进程改变了区域的景观结构,引起了景观格局的变化。以大长山岛两期景观分布图为数据源,运用景观生态学的理论与方法,利用景观格局指数定量分析了1995～2006年景观格局的动态变化特征,在此基础上借助CA-Markov模型对大长山岛2017年景观格局进行了模拟与预测,并探讨了景观格局演变驱动机制。结果表明：大长山岛在快速城市化的进程中,景观格局演变的总规律为自然景观向人文景观转变。1995～2006年间,主要表现为农用地、草地、商业及工矿用地面积减少,园林地、水体及水利设施、居民点及公共服务和其它用地增加;而2006～2017年间,表现为农用地、草地、园林地面积减少,居民点及公共服务、水体及水利设施、商业及工矿用地和其它用地增加,但在此期间各景观类型的面积减少和增加的速度有所放缓。Urbanization is one of the primary factors that contribute to the variations of regional landscape（ e. g. landscape structure and landscape pattern）. Landscape ecological analysis of two-phase landscape distribution in Dachangshan Island provided estimates of the local dynamic changes between 1995 and 2006. Simulation of the landscape pattern as well as the relative dynamic mechanism in 2017 was then conducted on the basis of these data through CAMarkov model. The result showed that the landscape pattern in Dachangshan Island modified from natural into artificial between 1995 and 2006 with the process of urbanization,which was characterized by the shrink of the farmlands,grasslands,commercial areas,industrial areas（ include mining areas） and the increase of garden lands,water facilities,residential quarters,public service areas,etc. In addition,simulation indicated the changes between 2006 and2017 was mainly displayed as the decrease of farmlands,grasslands,garden lands in the focus area and the increase of other lands,but neither the increase rate nor the shrink rate plunged in this period.
