对我国21个省、市、自治区的200座大、中、小型水库的鱼产量与理化性状,生物资源和形态与气候三大指标体系中15个生态因子分别作了各指标体系和综合指标体系的相关和回归分析。综合指标体系的逐步回归分析表明,在人工投放鱼种为主的养鱼水库,总磷、初级生产力和鱼种投放量与鱼产量相关密切,复相关系数R=0.6304。 Fifteen ecological factors in the three major indexes system of fish production, physicochemical traits, biological resources and morphology and climate in 200 large, medium and small-sized reservoirs of 21 provinces, cities and autonomous regions in China were respectively indexed and integrated index system Correlation and regression analysis. The stepwise regression analysis of the comprehensive index system showed that the total phosphorus, primary productivity, and fish species were closely related to the fish production in fish farms that were mainly stocked fish, with a complex correlation coefficient R = 0.6304.
