以南水北调中线邢石界至古运河南段（邢古段）为例，建立了该渠段水质模拟模型，模拟了污染物扩散的规律。根据模拟结果建立了按照污染物投入量、投入位置和报警响应时间进行快速插值输出峰值浓度、位置和污染带范围等结果的应急决策系统，并与模拟结果进行比较。结果表明：所建立的基于插值法的快速应急决策系统能够满足决策的精度要求，插值计算污染物浓度峰值与模拟结果相差在0．10 mg/L范围内，污染云团到达位置相差在500 m范围内，长度相差在100 m范围内，该系统具有快速响应、预测准确的特点。刑古段为多支流分岔口的渠道，数值模拟法建模以及运算较插值法所耗时间长，插值法可为快速决策节约时间。

Taking Xinggu section which is from Xingshijie to southern segment of ancient channel in the middle route of south-to-north water transfer project ( Xing-Gu segment ) for example , the paper estab-lished the model of water quality simulation in the section and simulated the rule of pollutant dispersion . According to the simulation results , it established emergency decision system in accordance with the a-mount, location and alarm response time of pollutant to carry out fast interpolation and output peak con -centration , location and range of pollution zone , and compared which with the simulation results .The re-sult shows that the fast emergency decision system can meet the accuracy requirement of decisiion , the peak concentration of pollutants and simulation results differ in the range of 0.10mg/L, the difference of location of pollution cloud cluster getting to is within 500m, the length difference of pollution cloud clus-ter is in the range of 100m.The system has the features of fast response , accurate prediction .The Xinggu section is a tributary of multi-channel .Compared with the method of numerical simulation ,the interpola-tion method can save time of quick decision .
