摘要
通过各种例子,利用数学分析方法,得出如下结论:①现有的许多环境质量综合指数都存在着可能的虚假性,而这种虚假性是由数学模式本身的性质所决定的;②对于一个数学模式来说,当综合指数一定时,单项指数的值域也是一定的。
In the light of various examples, this paper adopts the method of the mathematical analysis and obtaias the conclusions as follows, ①a lot of present compreheosive indices of environmental quality have the possible falsity which depends on the property of mathematical models; ②in regard to the mathematical model, the range of single ;ndex is certain when the comprehensive index is certain.
