摘要
从灰色理论建模特点出发 ,用加权均值生成数方法生成新数列 ,然后用生成的新数列建立改进的灰色加权GM (0 ,h)模型 ,根据该模型进行地下水开采量与地面沉降量的关系分析、沉降量预测 。
Based on the characteristics of modelling grey system theory ,new data sequence can be produced by weighted averages generating operation. Then, using the data sequence, the grey weight-model can be produced. According to the model, we can analyze the relations between groundwater quantity extracted and subsidence quantity, and can forecast subsidence quantity. The method has been proved to be useful.
