水母暴发的生物修复对策

Bioremediation countermeasures for jellyfish blooming

近年来,霞水母(Cyanea nozakii)、口冠水母(Stomolophus nomurai)在我国的东海、黄海、渤海以及韩国、日本沿岸均出现过大范围暴发现象,且暴发次数、暴发范围以及持续时间呈上升趋势。本文分析了海域富营养化以及N、P营养盐比例失衡等为水母暴发的主要原因,在此基础上,提出了植树造林、防止水土流失;保护湿地,增殖植物,以吸收N、P等营养盐类;近岸增殖大型海藻等生物修复对策。

In recent years, large-scale blooms of Cyanea nozaki and Stomolophus nomurai have occurred in the East Sea, Yellow Sea, Bohai Sea of China and the coasts along Korea and Japan in 2002 and 2003. The breakout times, scale and duration has taken on an upward trend. The reasons for Cyanea nozakii to bloom were analyzed, such as sea area eutrophication and unbalance of such nutrients as nitrogen and phosphorus. On such basis, the countermeasures were proposed as to prevent oil erosion, wet land protection and plant multiplication to absorb nutrients of nitrogen and phosphorus and bioremediation technology of large-scale seaweed planting in near-shore area etc.
