摘要：

利用浙江省海洋災(zāi)害公報(bào)中2006—2017年的赤潮災(zāi)害數(shù)據(jù)，分析了浙江近海赤潮的年、月和季節(jié)尺度的變化規(guī)律，同時(shí)分析了浙江近海赤潮的空間分布規(guī)律。將自適應(yīng)帶寬核密度分析方法應(yīng)用于赤潮災(zāi)害研究，分析了浙江近海不同海域受赤潮影響的程度。研究結(jié)果表明：浙江海域赤潮高發(fā)于春末和夏季，5月是發(fā)生峰值期；從年際情況看，近年來赤潮發(fā)生的累計(jì)次數(shù)和面積呈上升趨勢(shì)；浙江省赤潮主要發(fā)生在5個(gè)海域，按受赤潮影響的程度由高到低依次為舟山本島、嵊泗列島、溫州、寧波和臺(tái)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.
