说明：  灰色动态预测源代码预测水资源。灰色动态模型群模型 是改进的灰色预测模型，可以克服不稳定信息带来的 不良影响利用不同时段数据建立不同的灰色 GM(1,1)模型来构造灰色预测模型 群，分别对未来时刻的各项预测值进行统计计算，并将统计平均值作为预测值， 进一步提高了预测的精度和预测结果的可靠度。
(The gray dynamical prediction prediction source of water. Grey dynamic model group model is an improved gray prediction model can overcome the adverse effects of instability caused by the use of information to create different data at different times of gray GM (1,1) model to construct the gray prediction model group, respectively, each time in the future term prediction values ​ ​ of statistical calculations, and the statistical average as a predicted value, to further improve the accuracy and reliability of the prediction results of the prediction.)
