胶州湾环境演变与治理研究

Study on environmental variation and management in Jiaozhou Bay

调研了胶州湾近几十年的环境变化,结果主要是水域面积缩小、海岸线变迁、生物资源衰退、水体营养盐结构改变、环境质量下降等。胶州湾的环境现状调查相对滞后或局限于胶州湾的局部区域和个别项目,而不能满足社会经济发展的需要,鉴于胶州湾跨海大桥及海底隧道等大型建设项目的开工建设,亟需对胶州湾整体环境质量进行一次全面的综合调查,从而对近期的胶州湾环境有一个全面的掌握,为环胶州湾经济带的发展提供参考和依据。

This paper mainly deals with the environmental variation in Jiaozhou Bay in near decades. The results showed the shrinking of water area, increasing coastline, dropping of biological resources, change of nutrient structure, decrease of environmental capacity, and other environmental changes. In general, the integrated environment is reasonable in Jiaozhou Bay, but some areas are seriously polluted. Although there is a downward trend in the environmental quality, the rate of the descent becomes slower. With high-speed developing of ring economy belt in Jiaozhon bay, the environmental quality in Jiaozhou Bay is lag behind, which is not enough to the social economy development. There are many investigations and reports on the environment in Jiaozhou Bay, however the results of them are outmoded or limited in bayou and individual object. Now, the cross sea bridge of Jiaozhou Bay is building and the seabed tunnel is also planning, and there may be other large construction projects, so it＇s necessary to carry on the comprehensive investigation to the Jiaozhou Bay＇s environment. The investigation should be helpful to master the round environment in Jiaozhou Bay, which provides reference and basis for the developing of the ring economy belt of Jiaozhou Bay.
