摘　　要：从运畴学的角度出发,提出了基于带权线性规划的方法拟合变差函数,有效地保证了求解结果的非负性。将样本点建立空间三维网格索引,大大简化了待插点邻域样本的搜索过程,提高了Kriging属性建模的速度。最后结合OpenGL图形库,实现了属性模型的三维可视化,从而有效地实现了地质信息的定量化。Starting from the Operations Research,this paper proposes method of linear programming approach with weight to fitting variogram, effectively guarantee the non-negative of the results of solving. The sample points are established grid index of three-dimensional space, which greatly simplify the process of neighborhood searching sample points to insertion point, and improves the speed of model attributes based the general Kriging. In OpenGL graphics library ,it achieves the three-dimensional of property model , which will effectively realizes quantitative of the geological information.
