摘要
提出了一种水资源短缺的风险预测方案。通过对可能影响风险度量的8个因素与风险度量进行相关性分析,得出农业用水量和水资源总量与风险度量的相关系数最大。在此基础上采用最小二乘法拟合出了风险度量与农业用水量、水资源总量的二元线性回归方程,并利用该回归方程,预测出近2年的缺水风险度。
This paper introduces a water shortage risk prediction scheme.Data are used to analyze the correlation between the risk measurement Y and the eight possible influencing factors.The analysis proves that the agriculture water consumption and the total amount of water resources have very big relation with the risk measurement Y.Based on above studies,the two element linear regression equations are fitted by the least squares and the water shortage risk degrees in the last two years are predicted by the linear regression equation.
