摘要
讨论了环境质量评价指数方法的灵敏度，从计算方法的角度指出了前人在这方面的不足。按照分析数学模型的一般方法，提出了新的灵敏度定义，并据此对常用指数方法的灵敏度作了计算和分析，指出了大多数常用的评价方法在灵敏度方面的缺陷。从物理意义、灵敏度要求和计算方法等几个方面，提出了改进评价方法的原则和思路，并建立了一个新的评价方法。
The sensitivity of the index method used in environmental quality assessment is discussed Some defects in the previous studies in this realm are pointed out in terms of calculation. The definition of sensitivity is founded according to the principle of analyzing mathematic models The sensitivity of some methods used now in environmental quality assessment is studied It is found that most of existing methods are not satisfied in sensitivity. Principles for improving the existing index methods are proposed and a new index method is established
