摘要
罗非鱼(Oreochromis)是中国淡水养殖主要品种之一,在倡导绿色发展背景下,排污量问题值得关注。利用线性回归模型、聚类分析等方法,对2009-2016年中国罗非鱼养殖排污量变化趋势特征进行了分析。结果显示:罗非鱼养殖产量与排污量具有高度的同步变化趋势,罗非鱼养殖产量增长率快于同期排污量增长率0.45%;罗非鱼养殖产量每增加1%,污染物排放量将增加0.077%;各省份罗非鱼养殖排污量变化趋势可分为以广东等12个省份为代表的增长型和以内蒙古等17个省份为代表的下降型;罗非鱼养殖排污量将省份划分为3个类群,第一类群为广东,第二类群是海南和广西,其余省份是第三类群。建议为罗非鱼养殖规模的继续扩大,绘制一条绿色可持续发展道路。
Tilapia is one of the major species of freshwater aquaculture in China. Under the background of promoting green development,the issue of pollutant discharge volume is worthy of attention. The changes and trends of pollutants emissions of tilapia aquaculture in China during 2009-2016 were analyzed by using the methods of linear regression models and cluster analysis. The results showed as follows： The tilapia aquaculture production had a highly synchronous trend with the pollutants emissions,and the growth rate of tilapia aquaculture production was faster than the growth rate of pollutants emission by 0. 45% in the same period. For every 1% increase in tilapia aquaculture production,pollutants emissions will increase by0. 077%. The changing trend of the pollutants emissions of tilapia aquaculture can be divided into different growth types represented by the increasing type of 12 provinces such as Guangdong and the declining type represented by 17 provinces such as Inner Mongolia. The pollutant emissions of tilapia aquaculture can be divided into three groups by province,the first group is Guangdong,the second group is Hainan and Guangxi,and the remaining provinces are the third. The proposal is to continue to expand the scale of tilapia aquaculture in a green sustainable way.
