【摘要】在崇明岛功能区划的基础上,利用2006年的遥感影像对崇明东滩的景观类型进行解译,并对景观格局变化和植被覆盖度进行了分析与评价.结果表明:崇明东滩的景观面貌已经由原始潮滩演化出目前多达11种斑块类型.从景观空间形态指标和景观组分指标分析结果来看,崇明东滩的生境破碎化趋势已经显现,但从景观空间关系指标和Shannon均匀性指标分析结果来看,景观聚集度和连通度尚处于较高水平(分别为96.27和99.15),均匀度尚较大(0.59).崇明东滩的植被覆盖度主要集中在0.3至0.9之间,植被覆盖度整体上尚处于较高水平.%On the basis of functional zoning of Chongming Island, the landscape types of the Dongtan Area of Chongming Island was explained by using the remote sensing image of 2006, and the changes of landscape pattern and vegetation coverage were analyzed and evaluated. The results showed that up to 11 types of patches had formed in Dongtan Area at present. The indices of landscape space shape and landscape composition indicated the trend of habitat fragmentation in Dongtan Area, but the indices of landscape spatial relation and Shannon evenness showed the landscape aggregation and connectivity were still on a higher level (96. 27 and 99. 15 respectively) , and the evenness was still large (0.59). The vegetation coverage of
