应用多元统计分析方法处理了我国不同大骨节病区生态环境数据,方法包括聚类分析,主成份分析,因子分析,线性判别分析和模式识别。 本文得到以下结论:不同大骨节病区生态环境中微量元素对病情影响大同小异。人发硒的水平对病情影响起关键表征作用,可以作为判断病情之先期指标。有的病区内,元素锰对病情影响虽不重要,但有所反映。
The multivariate statistical analysis method was used to deal with the ecological environment data of different KBD wards in our country. The methods include cluster analysis, principal component analysis, factor analysis, linear discriminant analysis and pattern recognition. This article has the following conclusion: The trace elements in the ecological environment of different Kashin-Beck disease areas have similar effects on the disease. The level of human selenium play a key role in the impact of the disease, can be used as a precursor to determine the condition. In some wards, the impact of elemental manganese on the disease is not important, but it is reflected.
