摘要
基于渤海海岸带不同年份的遥感影像解译数据,计算出30 a来渤海海域因填海造地等人类活动所减少的滨海湿地和水域面积,分析了填海造地对近岸景观生态和周边海域水质的影响,并应用生态经济学的理论和研究方法,结合相关统计数据,对渤海填海造地导致的海洋生物资源损失、人文社会价值损失和消浪促淤护岸损失等技术指标进行了估算。结果表明,30 a来渤海人工岸线的长度增加了1 214.64 km,占岸线总长的42.57%;填海等新形成陆域面积2 278.34 km2,占渤海水域总面积的2.96%,估算由此造成海洋生物资源、人文社会价值和消浪促淤护岸的损失总计达2 506.20亿元。本文的研究结果可为制定渤海环境保护规划提供参考。
The decreased area of coastal wetlands and shallow sea due to marine reclamation was calculated based on the remote sens ing image. The coastal landscape ecology and water quality were analyzed. The total economic losses of marine biological resources, humanistic and social value, wave dissipation, siltation promotion and revetment were estimated according to the theory and research methods of ecological economics and related statistical data. The results showed that, during the 30 years, the length of artificial shoreline of Bohai Sea raised from 386.86 km to 1 601.50 kin, accounted for 42.57% of the total shoreline; the newly formed land area caused mainly by marine reclamation was 2 278.34 km2 , accounted for 2.96% of the total area, which resulted in a total loss of 250.62 billion CNY of the above three indicators. The results of this study can be used for scientific basis for the development of Bo hat Sea Environmental Protection Plan.
