摘 要:
用传统方法拟合平稳河流的水位流量关系,往往精度不高,与实际测量不能很好的重合。对于局部线性的水位流量关系,用系统辨识理论对其进行建模,利用最小二乘法,拟合精度明显提高。[著者文摘]

Abstract:
Any accurate results cannot be got in simulating the stage-discharge relationship of the steady river by the traditional methods. The results do not match the real value appropriately. The modeling based on the system recognition theory and using the least square method in the case of the partially linear relationship the simulation precision is greatly improved.[著者文摘]
