GIS数学模型构建与应用

为了将气象信息与地理信息紧密结合起来,用构建数学模型的方法,建立起气候要素与地理信息的GIS空间分析模型,分析气候要素的空间分布特征。结果显示:泰安市年平均温度与海拔高度、纬度、经度拟合方程的复相关系数为0.988,F检验值为130.37>F0.05,标准差为0.28,残差的绝对值最大为0.36,最小为0.01,回归效果极为显著。

The building of GIS mathematics model and its application

In order to combine weather information with geographical information together closely, the paper uses the method of structuring mathematics model to set up the key element of climate and GIS spatial analyze models to analyze the spatial distribution characteristic of the key element of the climate. The results show that the coefficient correlation of replying of the equation is 0.988 among the annual average temperature, height above sea level, latitude, longitude in Tai'an;the examining value of F is 130.37 that great than F0.05;the standard deviation is 0.28;the maximum value of surplus variance is 0.36;the minimum value of surplus variance is is 0.01;it is extremely remarkable to return to the result.
