| Popis: | 105 In Feburary 2016, Taoyuan became the first city in Taiwan to implement Total Quantity Control Methods for heavy metal contamination control in water. The purpose of this study is to analyze the strategy, including reassessing the area of delineation, quantifying the allowable pollutant load by using WASP model and calculating the mass of heavy metal contaminants in the farmland through irrigation water. WASP model in this study applies MAPE and R2 for verification. Of the first result of verification, MAPE measures 49.27%, R2 meassures 0.87; the second, MAPE measures 44.56%, R2 meassures 0.91. The two sets of results showed that the WASP model provides reasonable predictions matching current conditions. The results of WASP modeling showed that the allowable pollutant load of SanKuaiCuo channel still fails to meet ” Irrigation Water Quality Standards.” This will be solved by enhancing the level of Total Quantity Control Methods from 2nd-level to 1st-level. The WASP results indicated that farmlands around SanKuaiCuo channel are increased by 80 years from 48 to 128 when the 1st-level Total Quantity Control Methods is implemented. Applying ArcGIS for statistical data display helps provide visualized content for clearer presentation. The study can serve as reference for adjustments of the implementation of Total Quantity Control Methods in Taoyuan and other areas in the future. |
