| 摘 要： | 在简述Vegetative Filter Strips Model(VFSMOD)模型的功能和机制的基础上,通过野外小区试验资料检验该模型对国内植被过滤带净化效果的模拟情况,进而分析其适用性.结果表明,出流水量模拟值与实测值的偏差多在±15%以内,出流SS浓度模拟值与实测值的偏差多在±20%以内,出流水量和出流SS浓度模拟值与实测值的判定系数R2分别为0.995和0.889,模型具有较高的精度与较强的适应性,可用于植被过滤带的规划设计.

| Abstract: | The functions and mechanism of Vegetative Filter Strips Model (VFSMOD) had been introduced in this paper, and the applicability and performance ability of this model have been tested by plot experiment data. The results show that the relative deviations between simulated values and measured values of outflow quantity are within ±15%, while with the concentration of SS, the relative deviations are within ±20%, and the determination coefficients between simulated values and measured values for outflow and SS are 0.995 and 0.889 respectively. Therefore, the simulation precision of this model is satisfactory, the model can be used as a tool for the design of VFS. |
