| 摘 要： | 密切值法由于具有运算过程简明直观,评价结果优化等优点而广泛应用于环境质量评价中,但由于在运算过程中对不同的评价指标采取等权处理的方式而使结果有失偏差。通过引进目标差值率法及熵权法可对密切值法进行改进。将改进后的方法应用于福州市2001年-2006年大气环境质量评价中。结果表明,福州市2001-2006年大气环境质量总体良好.依据国家大气环境质量评价标准等级,2003年至2005年均达到一级标准水平,2001、2002、2006年均达到二级标准水平,这与实际情况能很好的吻合,说明了改进后的密切值法的评价结果客观、真实、可靠。

| Abstract: | On account of the virtue of compendious and intuitionistic operation processes and optimum evaluation results,the osculating value method is abroad applied to environmental quality evaluation.But,because of equalization of management manner on the process of the operation,the results of the osculating value method have some warp.The method can be ameliorated after into which the target dispersion rate method and entropy method are introduced.The ameliorated method is applied to the quality evaluation for at... |
