基于DRASTIC模型含水层易污染性模糊综合评价

摘要

Main problems in DRASTIC system,which is widely used abroad, arediscussed. This paper takes vulnerability of aquifer as fuzzy concept. A fuzzy comprehensive evaluation model based on the DRASTIC system is developed for assessing aquifer vulnerability. This model not only has strong physics basis, but also shows the ad vantages over the DRASTIC system in a case study.%分析了目前国外地下水易污染性评价中广泛采用的DRASTIC模型中存在的主要问题,将含水层易污染性定义为模糊概念;以DRASTIC模型为基础,建立了模糊综合评价模型.实例运用表明模糊综合评价模型不仅具有清晰的物理意义,还有很强的实用性.
