摘要
质量指数模型是一种环境质量评价方法，它是建立在多种环境要素和多种影响因子复合作用基础上，充分兼顾了各项评价因子对环境质量影响的动态特点和程度。在实际应用中，它的运算结果较为理想准确。本文阐述质量指数模型的原理及使用方法，并引用该模型对辽宁省东部山区崩塌、滑坡、泥石流灾害进行危险性预测。
Qualityindexmodel is a kind of environmental qualityevaluation method,whichis based on the compound of environmentalessential factorsandinfluence factors,reflectingtheinfluenced dynamic characteristics and extentsofeach evaluation factorson the environment quality. In practice,itsresultis preciselyandideal.The paper expounds the principle and application methodofquality index model, and by using the model,the hazard forecastingof collapse,landslide and rock-flow in East Liaoning is made in the end.
