用多级灰关联评价碧流河水库水环境质量

Multilevel gray relating evaluating the water environment quality in Biliuhe reservoir

依据灰数列间几何相似的序化分析与关联测度,来量化不同层次中多个序列相对某一级别质量序列的关联性。按离散数据间几何相似程度来判断关联大小,并进行排序。构造满足关联空间的关联离散函数,从中确定关联性最大,隶属程度最高的某个序列进行水库水环境质量评价。

according to the sequence analysis and relation measure of the similar geometry gray number array,the conjunction of multi-serial relating one level quality serial in the different levels is estimated.Based on the resemble geometry extent in dispersing datum to judge their relation and put up compositor,and form relating dispersing function of!satisfaction relation space,from which to ensure the serial which has the most relation and topmost subjection degree which can be used to evaluate the water environment quality in a reservoir.
