摘要
“拟合”实质上是对真实系统的一种仿真过程;模型的仿真性则是模型是否有效的关键所在。通常所指的拟合精度只是仿真性的一个判别标准,而更重要的判别标准应是模型本身是否能反映真实系统的内部结构。从本质上来看,地下水模型的仿真性主要取决于:水文地质条件的基本研究程度,包括实际问题中水文地质工作的精度和水文地质机理的研究程度;地下水模型的研究程度,包括摸型对水文地质实体的刻画程度,模型及计算方法本身的研究程度。只有把握了水文地质本质,模型才有“真”可仿;而只有提高了模型的研究程度,才有可靠手段去对实体进行仿真。两方面研究的紧密结合是提高模型仿真性及模拟精度的必由之路。
The emulation of ground water models ismainly based on two aspects: 1) Basic researchdegree of hydrogeology, including the precision ofhydrogeologic work in field and research degreeof hydrogeologic mechanism; 2) Research levelof ground water models, including depicting degreeof models for true hydrogeologic systems andre(?)carch level of the models and computing methodsthemsclves. The models can be used to emulate thetrue systems only with mastering the hydrogcologicesscnce; whereas there are rcliable means to emu-late them only with raising the research level ofmodels. Therefore, close combination of these aspe-cts is the only way for improving emulation andsimulating precision of models.
