介绍了一种基于水文模型参数变化检验来评价流域土地利用变化引起的径流特征响应的研究方法。针对目前以误差平方和作为参数估计目标函数会增加非线性系统局部优值等问题，基于函数曲面参数率定方法利用新安江模型对大坡岭流域分时期进行日模型参数率定。结果显示函数曲面参数率定方法在实际应用中是可行的，并且效率较高；参数变化检验方法对流域土地利用引起的径流特征响应研究是一种行之有效的方法。

A parameter-based change detection approach to evaluating runoff changes in response to land use changes is developed in this study .Most of the current parameter estimation methods are mainly based on the error sum of squares and maybe provide wrong information by the objective function ,for example ,increase unrelated local optima for nonlinear models .The Xinanjiang model is used to evaluate the newly approach in Dapoling watershed ,and a parameter method based on parameter function surface is applied to calibrated parameter values in different periods .The results show that the parameter method based on parameter function surface is feasible and highly efficient .The parameter-based change detection approach may be a useful alternative to watershed approach for examining land use changes and their impact on the runoff .
