【科技日报】南沙永暑礁：从海上戈壁到绿树成荫

Core Viewpoint - The ecological restoration efforts on the Nansha Yongshu Reef have led to the establishment of a near-natural salt marsh, significantly improving the local environment and biodiversity [1][2]. Group 1: Ecological Restoration Efforts - The Yongshu Reef has transformed from a barren coral sand beach to a green oasis, guided by the philosophy of "lucid waters and lush mountains are invaluable assets" [1]. - The establishment of a near-natural salt marsh is crucial for maintaining the ecosystem, regulating hydrology, and protecting the coastline [2]. - The survival rate of plants has increased to over 90% due to innovative soil improvement techniques, reducing the salinity of the reef sand from 1.38‰ to 0.443‰ [2]. Group 2: Biodiversity Enhancement - The number of plant species that can be cultivated on Yongshu Reef has increased from fewer than 20 to over 120, surpassing many urban planning standards for green space [3]. - The implementation of a marine environmental monitoring system allows for real-time tracking of water quality and coral health, contributing to the protection of marine biodiversity [3][4]. Group 3: Technological Integration - The monitoring system includes underwater cameras that provide continuous surveillance of the marine environment, enabling timely responses to ecological threats such as coral die-offs caused by crown-of-thorns starfish [3][5]. - The use of drones for marine debris inspection and remote sensing technology for monitoring vegetation growth enhances the efficiency and effectiveness of ecological management efforts [5].
