随着人类对海洋过度开发,我国近海环境问题日益突出,多处海域出现重度富营养化现象。目前,国内外不仅对海水富营养化现象日益关注,而且积极寻求有效的生态修复方案,其中应用大型海藻进行海洋生态环境修复得到普遍认可。大型海藻修复不仅有助于实现生态环境良性循环,构建稳定的海洋生态系统,还可使得经济发展与生态环境保护相协调。本研究基于我国近海生态环境问题以及相应的大型海藻修复策略展开综述,对现有的大型海藻生态修复特点及近海封闭海域、半封闭海域和开放海域生态修复工程案例进行总结,以期对我国近海富营养化海域生态修复起到一定的指导作用。 相似文献

黄海苏北浅滩海域春夏季浮游植物时空分布及其控制生态因子 总被引：1，自引：0，他引：1
The Subei Shoal is a special coastal area with complex physical oceanographic properties in the Yellow Sea. In the present study, the distribution of phytoplankton and its correlation with environmental factors were studied during spring and summer of 2012 in the Subei Shoal of the Yellow Sea. Phytoplankton species composition and abundance data were accomplished by Uterm?hl method. Diatoms represented the greatest cellular abundance during the study period. In spring, the phytoplankton cell abundance ranged from 1.59×10~3 to 269.78×10~3 cell/L with an average of 41.80×10~3 cell/L, and Skeletonema sp. and Paralia sulcata was the most dominant species. In summer, the average phytoplankton cell abundance was 72.59×10~3 cell/L with the range of 1.78×10~3 to 574.96×10~3 cell/L, and the main dominant species was Pseudo-nitzschia pungens, Skeletonema sp., Dactyliosolen fragilissima and Chaetoceros curvisetus. The results of a redundancy analysis(RDA) showed that turbidity,temperature, salinity, pH, dissolved oxygen(DO), the ratio of dissolved inorganic nitrogen to silicate and SiO_4-Si(DIN/SiO_4-Si) were the most important environmental factors controlling phytoplankton assemblages in spring or summer in the Subei Shoal of the Yellow Sea. 相似文献
