湖南省渔业敏感地区的问题与分析

Discussion on Fishery Sensitive Area in Hunan Province

以县、县级市或地级市的市区作为研究单元,将湖南省划分为102个单元,以各单元的渔业总产量作为渔业指标(Y),以渔业产值占GDP的比重作为经济指标(R),以单位面积超标污水排放量作为环境指标(W),采用SPSS17进行快速聚类后,对渔业指标和经济指标进行区域叠加,得出华容县、湘阴县、沅江市、南县4个单元为湖南省渔业最重要地区,结合环境指标聚类结果,确定沅江市和南县为湖南省渔业可持续发展特别关注地区。

The whole provinces of Hunan were divided into 102 units by county region.Using fishery yield of the unit as fishery index Y,the ratio of fishery output value to GDP as economic index R,and waste water discharge exceeding the discharge standard per unit area as environmental index W,after clustering analysis by SPSS17,layers of Y and R were superimposed which recognized Huarong county,Xiangyin county,Nanxian county and Yuanjiang city as the most important fishery areas in Hunan.When analysis combined with index W,Yuanjiang city and Nanxian county were recognized as areas attached special attention for the sustainable development of Hunan＇s fisheries.
