由于受频繁南下冷空气的影响，山东半岛沿海２０００年冬季改变了近２０ａ的暖冬现象，出现了海水温 度的异常偏低。海水温度的超常变化对该海域海洋生物的生长造成了一定影响，给许多养殖品种带来了危 害。本文对山东半岛沿海５个海洋站２０００年 １、２月的表层平均水温资料与历史资料作了统计分析比较．结 果表明，山东半岛沿海冬季２０００年１、２月表层平均海水温度比１９９９年同期海水温度降低２．５℃，比常年 偏低 ０．５℃．文章指出了海水温度变化对渔业的几方面影响。
Due to the frequent impact of southward cold air, the winter peninsula of Shandong peninsula changed nearly 20 years of warm winter in 2000, and the temperature of seawater was abnormally low. The extraordinary changes in seawater temperature have had some impact on the growth of marine life in the area, which has brought harm to many cultured species. In this paper, statistical analysis and comparison were made on the surface water temperature data and historical data of January and February 2000 at five marine stations along the coast of Shandong Peninsula. The results show that in January and February of 2000, the coastal sea temperature of Shandong Peninsula coast decreased by 2.5 ℃ than the seawater temperature of the same period of 1999 by 2.5 ℃, 0.5 ℃ lower than that of normal years. The paper points out several aspects of the impact of seawater temperature changes on fisheries.
