基于AHP的大尺度空间域矿山地质环境评价研究

以层次分析法(AHP)为基础,根据坡度特征将新疆北部分为两个子区,对新疆北部大尺度空间域矿山地质环境进行综合评价。发现高坡度评价体系的调整使得评价结果中的矿山地质环境受影响面积相比较于低坡度评价体系下的评价结果面积显著减小,降低了低坡度评价体系在高坡度子区评价结果的误差,较好的保持了高坡度子区的评价结果和低坡度子区评价结果的连续性。探索和论证了大尺度空间域矿山地质环境分区评价体系的可行性和必要性。

Reaserch on mine geological environment evaluation based on AHP in large scal spatial region

Based on the analytic hierarchy process (AHP), the working area of northern Xinjiang is divided into two sub-working areas according to the slope features, and the comprehensive evaluation of the mine geological environment in the large scale spatial region in the northern part of xinjiang was carried out.Found that the adjustment of high grade evaluation system that the evaluation results of the mine geological environment in comparison to the affected area under the low grade evaluation system of the evaluation results area is significantly reduced, reducing the low grade evaluation system in the high slope area error of evaluation results, the better to keep the high slope of the evaluation results and low gradient area the continuity of the evaluation results.The feasibility and necessity of regional evaluation system of mine geological environment in large scale spatial region are explored and demonstrated.
