淡水养殖池塘水质预警模型

摘要

在淡水养殖池塘水质评价指标体系及阈值确定的基础上,建立了淡水养殖池塘水质单因子状态预警模型、多因子状态预警模型、趋势预警模型和鱼类生存指数预警模型,确定了淡水养殖池塘水质预警的警级标准.利用预警模型对淡水养殖池塘水质进行监测,结果表明模型具有良好的实用性.%Based on evaluation index system of fresh water cultivation pond water quality and threshold definition, early-warning model of one factor condition, early-warning model of multiple factor condition,early-warning model of tendency and early-warning model of Pisces survival index were founded. Earlywarningrank standard of early-warning of fresh water cultivation pond water quality was determined.Through inspection, the model has favourable practicability.
