我国典型海洋生态系统健康状况及生物多样性分析

Ecosystem health status and biodiversity of typical marine ecosystems in China

  • 摘要: 基于海洋生态监控区的监测数据,本文分析了2004-2020年我国典型海洋生态系统的健康状况和部分海域海洋生物多样性的变化情况。结果表明,2020年20个典型海洋生态系统中有12个处于亚健康状况,7个处于健康状况,1个为不健康状况;12个河口、海湾、滩涂湿地生态系统均为亚健康或不健康状况;8个珊瑚礁、红树林、海草床中7个为健康状况,1个为亚健康状况。分析结果显示,河口、海湾生态系统整体呈好转态势,黄河口、长江口、珠江口、锦州湾和莱州湾生态系统从不健康状况转为亚健康状况;珊瑚礁、红树林、海草床生态系统近年来存在波动。本文的研究结果在一定程度上可以反映出我国主要流域和渤海综合治理的成效,但主要是从“不健康”状况转为“亚健康”状况,改善程度尚不理想,海洋生态环境保护的形势依然严峻。

     

    Abstract: Based on the data of marine ecological monitoring areas over the years, ecosystem health status and biodiversity of typical marine ecosystems in China from 2004 to 2020 are analyzed. The results showed that 12 of the 20 typical marine ecosystems are in sub-health status, and 7 are in health status, Among the 8 coral reefs, mangroves and seagrass beds ecosystems, 7 were in healthy condition, and 1 were in sub-health status. The ecosystem of estuaries and bays showed a trend of improvement, The results showed that the ecosystem of the Yellow River Estuary, Yangtze River Estuary, Pearl River Estuary, Jinzhou bay and Laizhou bay has changed from unhealthy to sub-health, the ecosystem of coral reef, mangrove and seagrass bed has fluctuated in recent years, which reflects the management effect of major river basins and Bohai sea in China, but the improvement is mainly from "unhealthy" to "sub-health", The grim situation of marine ecological environment protection has not changed.
