| 摘 要： | 文章简要分析了胶州湾海岸湿地退化过程以及海岸湿地退化对渔业生产和生物多样性保护的影响。近40～50a来由于围垦、滩涂养殖、污染、城市化、填海造陆、河流断流、海面上升等原因，胶州湾海岸湿地呈现严重的退化趋势，表现为各类湿地面积不断萎缩，潮上带湿地植被退化和景观分维数下降，潮间带湿地底质和潮下带湿地水质不断恶化等。认为海岸湿地退化导致胶州湾海洋渔业资源严重衰退和生物多样性受损，并且对珍稀鸟类保护有不利影响。

| Abstract: | The author summarizes reasons and process of degradation of the coastal wetlands in Jiaozhou Bay and its influences on fishery and biodiversity. In the last 40-50 years, due to innings, fishery, pollution, urbanization, decreasing of the river flow, and rising of the sea level, the coastal wetlands had degraded seriously. Some of natural coastal wetlands diminished, the natural vegetations changed greatly and the landscape of the supralittoral zone wetland fell into pieces. The sediment of intertidal zone wetland and water of subtidal zone wetland is getting worse. The author makes a conclusion that the degradation of the coastal wetlands is an important reason of degradation of fishery resources and biodiversity, and it also influences the protection of scarce birds. |
