  渤海是秒速pk10 国传统的四大渔场之一,养育了津冀鲁辽等省市数以万计的渔民。然而,随着现代化捕捞能力的提升,竭“海”而渔让这片浅湾不堪重负,“渤海无鱼汛”成为一代人的不堪记忆。更严重的是,“海底荒漠”出现在渤海湾浅滩: 清澈的水底,无鱼、无虾、无水草,无蟹、无螺,无牡蛎礁,只剩一片沙丘似的泥滩。

  更重要的是,将渤海生物多样性指标纳入下一步渤海治理考核体系。目前秒速pk10 国渤海治理“硬指标”主要有海水水质、入海河流断面水质、陆地排污口、湿地面积、海岸线长度等。专家建议,未来可以把反映生物多样性的指标纳入考核体系,把环境治理与生态修复统一起来,这样才能尽快恢复“海底的绿水青山”。
