土地防灾适宜性评价的变权集对分析-Vague集耦合模型
|
摘要
针对土地防灾适宜性评价复杂性、非确定性和动态性特征,以地表破裂危险性、砂土液化、软土震陷、崩塌滑坡、地震工程地质分区、场地类别为评价指标,设计并建立了以集对分析和Vague集理论为基础的耦合式土地防灾适宜性评价体系,并在评价体系中引入了变权模型。为了证明该耦合模型的适用性,文中对10组场地数据进行了示例验算,并与专家分析法、常权层次分析法等方法进行对比分析。其评价结果显示,耦合模型具有很好的稳定性,辨识结果更为精确,表明该方法具有较高的准确性和良好的实用性。
Aim at the complexity,uncertainty and dynamic of evaluation of hazardous resistant suitability for land,six sets of ions( surface rupture,liquefaction of sandy soil,settlement of soft soil,collapse and landslide,engineering geology classification,site classification) are selected for model verification. Coupling model,which is based on set pair analysis and Vague theory,is established to evaluate land hazardous resistant suitability in this paper. Variable weight theory is incorporated into the coupling model. Ten sets of data are selected as calculating example and then followed by a comparison with the expert analysis method and constant weight AHP model. The results show that the coupling model has good stability and the discriminant results are more accurate. It indicates that the coupling model has high accuracy and good practicability.
