评价单元划分是地质环境评价的关键步骤之一,然而其服务于评价的同时,由于划分后各单元孤立计算,会对评价结果产生一定的影响。文章针对该问题,类比基于点的面插值算法,提出了评价后处理方法流程。该方法对评价分区数据进行抽象化、插值、重分类等一系列后续处理,获取顾及区域空间关系的地质环境分区,并应用到徐州市采煤塌陷区地质环境评价中。
An evaluation element division is one of the key steps of the geological environment evaluation. While the services applied to the evaluation, due to each element was individually calculated after the division, certain influences would be affected to the evaluation results. According to the problem, on the analogy of the surface interpolation algorithm, a procedure of the evaluation post treatment method was provided. The method was applied to the abstraction, interpolation, reclassification and series post treatment of the evaluation division data. The geological environment subregion of the related area space relationship was obtained. Finally, the method was applied to geological environment evaluation of the mining subsidence area in Xuzhou City.
