摘　　要：基于中心点三角白化权函数的灰色评估是灰色聚类分析法中划分对象类别的一种新方法,是对灰色的三角白化权函数的进一步改进,从而获得更加理想的结果。将这种方法应用于黑龙江省庆安县地下水水质评价中,经过研究表明,基于中心点三角白化权函数灰色评估评价得出的结果更加客观,与当地的实际情况也更加接近,这也为今后地下水水质评价研究方法研究提供了新的思路和借鉴。Grey assessment method based on the Central Point Triangle Whiten Weight Function is a new method to classify objects categories in Grey clustering analysis. It is also a further improvement of grey triangle whiten weight function to obtain a more desir- able results. In this paper, Grey assessment method based-on the Central Point Triangle Whiten Weight Function has been applied in assessment of groundwater quality in Qing＇an county, Heilongjiang province. The study shows that the results of Grey assessment method based on the Central Point Triangle Whiten weight Function are more accurate, objective and closer to actually local situation..So it is clear that Grey assessment method based on the Central Point Triangle Whiten weight Function can provide a new idea and reference for future research.
