| 摘 要： | 针对水环境系统权重分配问题，从建筑系统客观背景入手，以环境因子监测样本资料为信息源，通过构造关联信息矩阵，并采用旋转正交转变换的主成分分析法，定量地描述了交五因子在整体系统的贡献，最后依贡献量大小识别对应各个因子的权重值，实例表明，该方法物理意义清晰结果客观合理。

| Abstract: | Weight distribution problem is a main content in water environmental system. Based on objective background and monitoring data, a kind of correlative information matrix was presented. Then adopting main component analysis method of revolving alternation, the weight of each environmental factor could be determined by its contribution. The application example indicated that the approach was clear in physical meaning and rational in result. |
