中文摘要：

以日照万平口潟湖湿地为研究对象,利用遥感影像及GIS技术,选取景观格局指数,对1990-2014年万平口潟湖湿地的景观格局变化进行研究。结果表明：自1990年到2014年,潟湖浅滩、绿地、建设用地的面积显著增加,养殖池和耕地在潟湖湿地范围内已全部转化为潟湖浅滩、绿地和建设用地。潟湖湿地的景观格局指数表明,湿地景观类型多样性呈下降趋势,均匀度指数增加,聚集度和连通性显著上升。从景观格局分析的结果来看,奥林匹克水上公园的建设在一定程度上优化了万平口潟湖湿地的景观格局,湿地景观破碎化程度有所下降,为了更好地开发和利用潟湖湿地资源,提出了一些保护对策和建议。

英文摘要：

With uses of RS images and GIS technologies, wanpingkou lagoon wetland in Rizhao was taken for a case study to investigate changes of landscape pattern of the wetland from 1990 to 2014 using landscape pattern index. Results indicated that the areas of shallow lagoon, green land and construction land increased significantly. Fishery ponds and farmland within the scope of the lagoon wetland werc all converted into shallow lagoon, green land and construction land. Overall, the changes of wetlands landscape pattern index reflected that the landscape diversity tended to decrease, the landscape evenness index tended to increase, the intensity of aggregation and the connectivity tended to increase significantly. From the results of analysis of the landscape pattern, the constrtiction of the Olympic Water Park optimized the landscape pattern ofwanpingkou lagoon wetland to a certain extent, the extent of landscape fragmentation more or less decreased. In order to better develop and utilize the resources of the lagoon wetland, strategies and measures were proposed for wetland protection.
