生态系统服务价值评估在钦州市海岸线保护与利用规划中的应用研究

Application of ecosystem services value assessment in coastline protection and utilization planning of Qinzhou city

科学评估海岸线生态服务价值(ESV)是海岸线保护与利用的重要前提,有助于判别海岸线保护与利用级别,有助于优化海岸线的管理。本文以广西钦州市海岸线为研究对象,以海岸线向海陆两侧各1 km区域为研究范围,评估了钦州市海岸线生态系统服务价值,探索了生态系统服务价值评估在编制海岸线保护与利用规划中的应用,结果表明:ESV较高的区域主要分布在茅尾海北部、七十二泾、三娘湾以及大风江部分地区,ESV较低的区域分布在钦江入海口、金鼓江南部以及大风江西南侧部分地区;ESV评估可以从海岸线资源环境特征上把控其保护级别与开发利用价值,并为海岸线保护与利用规划的编制提供基础支撑。研究成果可为海岸线规划管理以及后续深入研究提供借鉴。

Scientific evaluation of the ecosystem services value(ESV)of coastline is an important prerequisite for coastline protection and utilization,which is conducive to identifying the level of coastline protection and utilization and optimizing coastline management.In this paper,the coastline and areas within 1 km of each side of it in Qinzhou,Guangxi was selected as a case study to evaluate ESV of the coastline and explore the application of ESV in the coastline protection and utilization planning.The results indicated that higher ESV are mainly distributed in the northern part of Maowei sea,Seventy-two brook,Sanniang bay and Dafeng river,whereas lower ESV are in the estuary of Qinjiang River,the south part of Jingu River and the south-west part of Dafeng River.ESV can guide and control the protection level and development and utilization value from coastline resources and environment characteristics,and can provide basic support for the coastline protection and utilization planning.The research results can provide reference for coastline planning and management and especially further research.
