| 摘 要： | 将投影寻踪分类模型应用于水环境质量综合评价中,利用基于实码的加速遗传算法来优化投影方向,将多维数据指标转换成低维子空间,通过寻求最优投影方向来计算投影函数值,从而根据投影值的大小进行水环境质量评价。结合实例进行了应用,结果较令人满意,为水环境质量评价提供了一条新的方法和途径。 |

| Abstract: | In application of Projection Pursuit Evaluation model to evaluate water environment quality,accelerating genetic algorithm based on real coding is introduced to optimize the projection direction so that multi-dimension data can be turned into low dimension space.Then the value of projection function can be calculated by means of seeking the optimal projection direction.Thereby, according to the value,the water environment quality can be evaluated comprehensively.This paper provides a new way to evaluate groundwater quality.The result shows that it is feasible and reasonable. |
| Keywords: | Genetic algorithm projection pursuit water environment evaluating |
