利用浙江省海洋灾害公报中2006—2017年的赤潮灾害数据,分析了浙江近海赤潮的年、月和季节尺度的变化规律,同时分析了浙江近海赤潮的空间分布规律。将自适应带宽核密度分析方法应用于赤潮灾害研究,分析了浙江近海不同海域受赤潮影响的程度。研究结果表明:浙江海域赤潮高发于春末和夏季,5月是发生峰值期;从年际情况看,近年来赤潮发生的累计次数和面积呈上升趋势;浙江省赤潮主要发生在5个海域,按受赤潮影响的程度由高到低依次为舟山本岛、嵊泗列岛、温州、宁波和台州。 |
Based on the red tide disaster data between 2006 and 2017 obtained from Zhejiang Province marine disaster bulletin, this paper analyzes the characteristics of the interannual, monthly and seasonal variations and spatial distribution of red tide in the Zhejiang coastal area. The adaptive bandwidth kernel density analysis method is used to analyze the impact level of red tide in different parts of the Zhejiang coastal area. The results show that red tide occurs most frequently in late spring and summer with the maximum in May. At an interannual scale, the accumulative frequency and area of red tide show an increasing trend in recent years. In the Zhejiang coastal area, red tide mainly occurs in five regions, which are Zhoushan, Shengsi, Wenzhou, Ningbo and Taizhou according to the degree of red tide influence in descending order. |
