摘　　要：本文从景观格局、海洋资源、植被资源三个角度,探讨了2000年至2013环渤海湾海岸带不透水面空间格局变化对环境压力的影响。研究结果发现:(1)2000年至2013年,不透水面斑块面积增加,斑块密度减少,呈现团聚状分布格局;(2)2000年至2013年,滩涂、0-5m海域和5-10m海域空间资源的损失量分别为464.32km2、151.76km2和12.81km2;(3)研究区内城市建成区的植被减少和不透水面扩张之间呈现明显的此消彼长趋势。This paper analyzed the environmental pressure in Bohai Bay coastal zone during 2000 to 2013 . The effect of impervious surface area expansion in terms of landscape pattern, ocean and vegetation resource was discussed. It finds that （1）the area of impervious surface area is increasing and the PD index is descreased from 2000 to 2013. （2）the im-pervious surface area occupies great resources, about 464.32 km2 tidal-flat resource, 151.76 km2 in 0-am strip and 12. 81 km2 in 5 -10m strip; （3）there is no homogeneity completely between of impervious surface area expansion and veg-etation decrease, especially in rural area compared with center metroplises.
