摘要
模型得出的数据系列与观测数据的拟合是多解的。观测数据系列是拟合的约束集,而边界、参数等则为可调集,可理集与约束集之比标志着拟合的自由度。不应一味追求“最佳的拟合精度”,而应当在增强约束的前提下去寻求“满意的拟合精度”。水文地质定性分析作为一种约束框架可以提高拟合的逼真程度。拟合并非一次性的行动,而是一个不断逼近的过程。
The fitting of the data series produced from model to the data series measured has the character of multi-solution. The measured data series is a constraint set for fitting, and the hydrogeological boundaries, parameters consist of a adjustable set. The ratio of adjustable set to the constraint set represents the free degree of fitting.
It is unsuitable to look for just the best precision of fitting, and our reasonable target must be a more satisfied precision of fitting under enhanced constraint condition.
Quantitative analysis for hydrogeological conditions. as a constraint framework, con raise the reliability of fitting. Hydrogeological fitting dose not mean an once-action, but is a continuous step-by-step approach.
