摘 要: 分析了人类利用技术手段来替代和恢复生态系统服务功能的一些尝试(如红树林海水养殖、人造海堤、人造礁等),讨论人工技术能在多大程度在替代海岸带景观的生态系统功能,生态系统的恢复项目是否既能恢复生态系统为人类提供的直接利用价值,也能恢复系统面对未来干扰的自我恢复能力。研究表明,替代项目仅能替代生态系统的某些功能,且需要耗费巨大的工程和维修费用。另外,恢复项目往往没有考虑大尺度的过程,如红树林、海草床、珊瑚礁之间物理的、生物的、生化的交互作用,造成恢复生态系统的生物多样性及抗干扰能力降低。 The some attempts for the substitution and restoration of ecosystem services (e.g. aquaculture in mangroves, artificial seawalls, reefs) were done. What degree the technologies can substitute the ecosystem services in the seascape and how the ecosystem can restore the reestablish not only in the functions of direct value to humans, but also the ability of the system to cope with the future disturbance, all of them is analyzed. The technological substitutes only provided the ecosystem services and entails huge engineering and maintenance costs. Further, the restoration usually does not focus on the large-scale processes such as the physical, biological and biogeochemical interactions between the mangroves, seagrass beds and coral reefs.
