摘要
长三角海岸带是长江三角洲与东海间的重要过渡性区域,基于联合国千年评估提出的生态系统服务框架,以生态学为原理、以遥感反演技术为手段、借助经济学方法,对2005年及2008年长三角海岸带的10项生态系统服务价值进行了评估。结果表明,长三角海岸带2005及2008年的生态系统服务总价值分别为1 235.92、1 493.04亿元,与长三角地区实际GDP对比得出,生态系统服务价值实际降低,海岸带生态环境退化;对于不同的生态系统来说,林地、耕地、湿地的生态系统服务价值较高,为增强生态系统可持续发展应重点加以保护;对于不同的生态系统服务功能来说,旅游娱乐服务、土壤保持、调节水源为价值量最大的3项服务,而调节空气质量、精神文化服务、养分循环为价值量最小的3项服务。
The Yangtze Delta Coastal Zone is an important transitional region between the Yangtze Delta and East China Sea.Based on the framework of Millennium Ecosystem Assessment of United Nation,this study evaluated 10 ecosystem services of the study area in 2005 and 2008,using ecological theories,ecological economic principles and remote sensing method.It shows that the total value of the Yangtze Delta Coastal Zone was 12.36 billion Yuan in 2005 and 14.93 billion Yuan in 2008.Compared with GDP of the Yangtze Delta,the ecosystem service value had declined in fact.The coastal environment had degenerated.To different ecosystems,the value of forest,field and wetland was relatively high,which suggests that they should be protected to enhance the sustainable development of ecosystems.The services of tourism,soil protection and water holding capacity made three largest values,while the services of O2 releasing,cultural,nutrient cycling mad three smallest values.
