Core Viewpoint - Guangdong Province is accelerating the construction of a comprehensive protection and governance framework for marine ecology, aiming for integrated land-sea development and protection during the 14th Five-Year Plan period [1][2]. Group 1: Marine Ecological Protection Achievements - Over 200 kilometers of coastline have been restored, with more than 40 kilometers of new ecological restoration coastline added, exceeding national targets for maintaining natural coastline [1][2]. - The area of newly created mangroves ranks first in the country, with over 4,900 hectares of new mangroves and more than 2,600 hectares of restored mangroves, surpassing the 2025 target of 1,500 hectares [3]. - The proportion of excellent water quality in coastal waters is expected to reach 91.2% by 2025, with significant improvements in nearshore water quality over the past five years [1][3]. Group 2: Regulatory Framework and Funding - Guangdong has established a marine ecological protection red line covering 16,600 square kilometers, accounting for 25.62% of the province's marine area, and implemented detailed management of coastline protection [2]. - The province has received over 3.3 billion yuan in central and provincial funding for marine ecological restoration projects, with 33 projects initiated [2]. Group 3: Pollution Control and Water Quality Improvement - The province has completed a comprehensive survey of over 9,900 river mouth pollution outlets, achieving a 100% remediation rate in six cities including Guangzhou and Shenzhen [3]. - By 2025, the total nitrogen concentration in rivers entering the sea is expected to show a negative growth compared to 2020 levels, with 73.9% of the water quality in the Pearl River Estuary meeting excellent standards [3].
