主要水污染物总量控制的多层次灰色综合评价法研究

摘要

总量控制是我国一项重要的环境保护制度,但由于其影响因素复杂,一直没有较好的方法来全面评价地区总量控制水平.本文基于灰色系统理论,利用灰色关联度建立了主要水污染物总量控制的多层次灰色综合评价法.将该方法应用于我国27个省级地区主要水污染物总量控制综合水平评价,结果表明,本方法是一种有效的综合评价方法,能够反映多因素影响下的地区总量控制制度实施情况,较好地克服了以往单因素评价的不足.%Total amount control is an important environmental protection policy.It is difficult for us to get a comprehensive assessment of it, because of the complexity of the influencing factors.In this study, a multi-level grey comprehensive evaluation method was established for total mount control of water pollutants by using grey relational analysis.The total amount levels of 27 provinces were calculated with this method.Those levels can more comprehensively reflect the situation of water pollution control in provinces than single-factor evaluation.
