【摘要】 结合某流域水温原型观测资料,通过分析水温与气温、太阳辐射、湿度和风速之间的相关关系,采用最小二乘法建立了水温与气温、湿度和风速三者之间的多变量函数方程式,提出了一种利用气象因子估算天然河道水温的新公式。研究成果可用于缺乏水温监测资料河流的水温估算,为流域开发的环境影响评价提供科学依据。更多还原

【Abstract】 On the basis of the field data of water temperature,a new formula for estimating water temperature of river by using meteorological factors is put forward by using the method of least squares.The new formula can be used to estimate the water temperature of river where there is no water temperature monitoring data,and can provide the scientific foundation for environmental impact assessment of river basin development.更多还原
