摘　　要：为研究池塘养殖环境中不同水层水质因子与气象因子组间的相关关系,对池塘养殖环境中不同水层(水下10、60和110 cm)的水质因子(水温、DO、p H、ORP)与气象因子(气温、气压、湿度、日照、风速、风向、雨量)等11个因子进行监测,并对这3组进行典型性相关分析,得出它们之间的定性、定量规律,旨在提取出影响水质的关键影响因子,为进一步预测不同水层水质以及智能决策奠定基础。研究结果表明,水温是水质因子中反应最活跃、最密切的因子,水温的关键影响因子为气温;DO和p H是水质因子中相对复杂的因子;DO的关键影响因子为水温、光照、气压、气温和湿度;p H的关键影响因子为水温、DO、气压、气温和湿度;ORP与气象的密切程度不高(r<0.3),可以不予考虑。In order to study the correlation-ship between water quality factors of different water layers in pond aquaculture environment and meteorological factors, 11 factors of the water quality （Water Temperature, DO, pH, ORP） and meteorological factors （Air Temperature, Air Pressure, Solar radiation, Humidity, Wind Speed, Wind Direction, Rainfall） were monitored, and canonical correlation analysis was used for 3 groups＇ factors. The results showed that water temperature is the most active and most closely reaction in water quality factors, the key influence factor for temperature is the water temperature. DO and pH are relatively complicated factors of water quality factor, the key influence factors for DO are water temperature, solar radiation, air pressure, air temperature and humidity, the key influence factors for pH are water temperature,. DO, air pressure, air temperature and humidity. The correlation-ship between ORP and meteorological factors were weak （ r 〈 0.3 ） , which cannot be considered.
