摘　　要：采用离散线性随机序列分析方法进行公路施工期污染源分布特征数据信息流模型构建,对公路施工期污染源分布特征数据分布式时间序列进行奇异值分解,将大规模的公路施工期污染源分布特征数据问题变为一系列小规模特征分解运算问题,结合公路施工期污染源的分布区情况进行描述性的统计回归分析和分段样本检测,实现公路施工期污染源分布的数值模拟优化。采用该方法进行公路施工期污染源分布的数值模拟的准确度较高,拟合性较强,提高了对污染源的检测判断能力。This study proposed a numerical simulation method for the distribution of pollution sources during highway construction period based on descriptive statistical analysis and regression detection.The discrete linear random sequence analysis method is used to construct the information flow model of the distribution data of pollution source during highway construction period,and the singular value decomposition of the distributed time series of the distribution data of pollution source during highway construction period is carried out.In this paper,the distribution characteristic data of pollution source during highway construction period is changed into a series of small scale characteristic decomposing operation problems,and combining with the distribution of pollution source during road construction period,the descriptive statistical regression analysis and segmented sample detection are carried out.The distribution of pollution sources during highway construction is optimized by numerical simulation.The simulation results show that the accuracy of numerical simulation of pollution source distribution during highway construction is high and the fitting ability is strong,and the ability of detecting and judging pollution source is improved.
