长江上游水温监测及水温和气温关系研究

Monitoring of Water Temperature and Changing Relationship Between the Water Temperature and Air Temperature in the Upper Yangtze River

通过对重庆某一实际项目的水源侧多个气象参数的监测,分析了长江江水温度随空气温度的变化关系,并与其他测试单位测得的数据进行比较,验证了本测试结果的合理性;通过3种数学拟合比较得到基于Boltzmann模型的江水水温和实测各个温度下江水温度平均值的拟合曲线,经过将拟合计算水温与实测各个空气温度下江水温度平均值进行比较分析,得出73.4%的测试水温与拟合水温的误差在[-1,1]℃之间。

The changing relationship between the water temperature and air temperature in the upper Yangtze River is mainly analyzed according to the test data of the water side of a water heat pump project in Chongqing city.The rationality of the date is validated by this test,comparing with the test data by other units.A fitting curve is educed,based on Boltzmann model of the air temperature and the average of the corresponding water temperature.Through the analysis on the difference between the air temperature and the average of the corresponding water temperature,it can be concluded that 73.4% of the errors are in ℃.
