武汉市渔业生产力与其人文影响因素的灰色关联性分析

以位于长江中下游平原的＂百湖之市＂——武汉市为研究对象,利用灰色关联模型分析了武汉市渔业生产力与其人文影响因素的互动关系。研究结果表明：各项人文影响因素与渔业中鱼类、虾蟹类、贝类和其他类生产量的关联度均在0.6以上,人文因素是影响渔业产量的基本因素;总体上化肥用量、养殖面积和城市化对渔业生产的影响较大,而人口密度、人口素质和人均GDP的影响较小;化肥用量、城市化、养殖面积和人口密度是影响武汉渔业生产中鱼类、贝类和其他类产量的主要人文驱动因子;人均GDP和人口素质是影响武汉虾蟹产量的主要人文驱动因子。

Grey Relational Analysis on the Fisheries Productivity and the Human Affecting Forces of Wuhan

We take the Hundred Lake City of Wuhan city which is in the plain of the Yangtze River as research object,and use the model of grey relational analysis to analyze the interaction of the productivity of their fisheries in Wuhan and its human affecting forces.The research results show that：human affecting forces of the fisheries have more than 0.6 correlations with fisheries in fish,shrimps and crabs,shellfish and other types of production,human factor is basic to the fisheries;overall fertilizer use,breeding area and urbanization have a greater effect on fisheries production,however,Population density,the quality of the population and per capita GDP have the less influence;the major human driving factors which have affection for the fish production of fish,shellfish and other types in Wuhan are fertilizer use,urbanization,farming area and population density.The major human driving factors which have affection for the fish production of crab are per capita GDP and the quality of the population.
