分析了莱州湾地区水资源对气候波动的敏感性，旱涝频率及水资源污染等问题。主要结论有：水资源对气候波动很敏感，降水增加 １０％，全区水资源总量将增加 ２１％；降水减少 １０％，全区水资源总量将减少 ２８％。旱涝频繁， ３０ ａ中共发生等级在涝以上的雨涝１０次，等级在旱以上的干旱１４次。在气候偏旱时期，特大旱共发生４次，而在气候偏湿时期仅发生１次特大旱；在气候偏湿时期，大涝及特大涝共发生４次，而在气候偏旱时期仅发生特大涝１次。该区水资源已受到严重污染；尤其是在海水入浸区，水污染已造成严重危害。
This paper analyzes the sensitivity of water resources to climate fluctuations, the frequency of droughts and floods and water resources pollution in Laizhou Bay. The main conclusions are: water resources are sensitive to climate fluctuations, precipitation increased by 10%, the region’s total water resources will increase by 21%; precipitation decreased by 10%, the region’s total water resources will be reduced by 28%. Droughts and floods frequently occurred in the past 30 years, with 10 floods and floods above the flood level and 14 drought levels and above. In the climate drought period, a total of 4 times a severe drought, and in the humid climate only one exceptionally severe drought; climate humid period, floods and floods occurred a total of 4 times, and only occurred during the drought climate Big flood 1 times. The water resources in this area have been seriously polluted; especially in the seawater inundation area, water pollution has caused serious damage.
