摘要
为了解浙江省及省内主要海水养殖区的自身污染状况,文章利用2005—2021年《浙江省渔业经济统计资料》及《第一次全国污染源普查水产养殖业污染源产排污系数手册》中部分养殖品种的产污系数等数据对浙江省海水养殖活动产生的污染量进行初步评估,并经过换算将不同种类的污染物统一用等标污染负荷表示。同时对浙江省主要沿海城市产生等标污染负荷情况及海水养殖产量进行时空演化分析。结果显示,2005—2021年浙江省海水养殖等标污染负荷量累计超过70亿m~3/a。总体趋势为先波动上升,然后连续上升。等标污染负荷最高地区是宁波市,污染负荷量累积达271 769.2万m~3/a,其次分别为台州市、舟山市和温州市。从品种角度来看,贝类产生等标污染负荷最高;从养殖方式来看,筏式养殖和底播产生等标污染负荷最高。时空演化分析表明,浙江海水养殖业自身污染与海水养殖产量变化基本同步,等标污染负荷与海水养殖产量都呈现明显的增长态势。
In order to explore the pollution status of main mariculture areas in Zhejiang Province,this paper made a preliminary assessment of the pollution generated by mariculture activities in Zhejiang Province,by using the data of the fishery Statistics of Zhejiang Province from 2005 to 2021 and Manual for the First National Survey of Pollution Sources Production and Discharge Coefficient of Aquaculture Pollution Sources.And different kinds of pollutants were converted to equal-standard pollution loading.Meanwhile,an analysis of spatio-temporal evolution of equal-standard pollution loading and mariculture yield of major coastal cities in Zhejiang Province was conducted.The results showed that,the cumulative equal-standard pollution loading of mariculture in Zhejiang Province from 2005 to 2021 exceeded 700000×104 m3/a,and revealed a trend of wavelike rise first and continuously rise after.Equal-standard pollution loading the highest is the highest in Ningbo with the cumulative volume of 271769.2×104 m3/a.followed by Taizhou,Zhoushan and Wenzhou.From the perspective of mariculture species,shellfish produced the highest equal-standard pollution loading.And from the perspective of mariculture mode,raft cultivation and bottom sowing produce the highest equal-standard pollution loading.Spatio-temporal evolution analysis showed that,the changes of pollution and mariculture yield in Zhejiang were basically synchronized,and the equal-standard pollution loading and mariculture yield showed obvious growth trend.
