以1990年、2000年、2010年的遥感影像为基础数据，采用景观生态学相关方法分析了山东半岛东部（烟台市、威海市）湿地景观格局的变化特点，并选择部分能代表气候及人类活动的因子，分析当前湿地景观格局变化的驱动力。结果表明：自然湿地总面积呈减少趋势，其中海域湿地与河流湿地降幅最大，但人工湿地面积增长迅速；景观格局指数显示，研究区景观形状趋于复杂化，斑块类型更加多样化，景观破碎化程度日益提高；研究区湿地生态系统的景观格局是自然环境和人类活动综合作用的结果，气候波动、人口增长、经济和城镇化发展、政策制定对湿地的景观格局影响深刻，人文驱动力中人口因子占主导地位。%Based on the remote sensing data of the eastern area of Shandong Peninsula (Yantai City and Weihai City)in 1990,2000 and 2010 and using landscape ecological method,this paper analyzed the dynamic changes of wetland landscape pattern. It chose the factors which can represent the climate and human activities to analyze the driving force of these factors on the current wetland landscape pattern. The results show that the total area of natural wetland has decreased,which the sea wetland and river wetland of the largest decline,but the artificial wetland area increases rapidly;the landscape index indicate that the shape of the wetland landscape in the survey region tends to complicate,the patch shape types are more diversified and the landscape fragmentation is more aggravate;the landscape pattern of the wet-land ecosystem is a result of the combined action of natural environment and human activities. Among these factors,climatic variation,accre-tion of population,economic development,urbanization,and policy-making have great effects on the wetland landscape pattern,while the population factor is the dominant factor.
