中文摘要：
探讨了比例下降模型和灰色预测型线性规划模型机理及比例下降-灰色预测型线性规划模型建模和求解的过程。根据大气污染控制规划实例，在该区域内污染源按等比例下降方式排放污染物构建模型，运用单纯形法对模型求解并对规划结果进行灵敏度分析。结果表明，比例下降-灰色预测线性规划模型适宜含有不确定性信息的区域大气污染控制规划，尤其在空间尺度较大的污染控制区内，针对不同污染源规划相应的污染控制方案时具有适应性。
英文摘要：
It was discussed that mechanism of ratio decrease and the grey predictive linear programming model as well as modeling and solving process of the models.Based on an instance of air pollution control programs, the model was established by means of ratio decrease for discharge pollutants from pollution sources in the region, and it was solved by simplex method. The sensitivity of planning results was analyzed. It was showed that ratio decrease and the grey predictive linear programming model appropriated regional air pollution control programs with uncertainties information. The model had adaptability to correspondingly plan control programs for different air pollution sources especially in the larger spatial scale pollution control districts.
