Abstract: 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.
