以几何精校正后的1992年和2012年遥感（RS）影像为数据源，对渤海湾沿岸近20年海域开发活动进行了分类统计，并参照现有生态系统服务价值当量研究成果，对该海域生态系统服务价值变化进行了估算和分析。结果表明，近20年来对渤海湾沿岸的高强度开发导致海岸带生态系统服务价值损失较大，约为43.79亿元/年，其中，建设用地、裸露地、盐田和废物处置用地占用原来开阔环境水域和滩涂导致单位面积生态系统服务价值损失最大，损失的价值总量分别为40.63亿元/年、12.45亿元/年、1.23亿元/年和0.17亿元/年；天津市沿岸海域的生态系统服务价值损失了18.12亿元/年，占研究区域生态系统服务价值总损失量的41.38%。

In this paper, the sea use activities in coastal areas of the Bohai Bay in recent 20 years were analyzed based on the precisely corrected remote sensing images in 1992 and 2012, and the value change of ecosystem services in the areas was evaluated, according to the recently published ecosystem value equivalent. It was shown that, because of highly intense utilization in recent 20 years, the loss of marine ecosystem services in coastal areas of the Bohai Bay was great, which was about 4 379 million RMB per year. The greatest losses of marine ecosystem service value per unit area were caused by the construction land, bare land, salt pan, and waste disposal land occupying the original water areas and marshy grounds, which were about 4 063 million, 1 245 million, 123 million and 17 million RMB per year, respectively. The loss of marine ecosystem service value in Tianjin was about 1 815 million RMB per year, accounting for 41.38%of the total loss.
