目的：探讨水源水质与胃肠道疾病之间的关系,以及胃肠道疾病的发病规律。方法选择淮安市2006年1月至2013年12月间水源水质指标及胃肠道患病例数,并进行相关性分析,然后进行具有输出时延反馈的非线性自回归(NARX)神经网络模型的构建、训练及模拟。结果水源水质的石油类、挥发酚、总砷、总汞、6价铬、氟化物及粪大肠菌群等指标与发病人数有显著的相关性。经过训练后NARX神经网络的可决系数为0.716,拟合效果比较理想。结论水源水质与胃肠道疾病之间存在一定的相关性,基于 NARX 神经网络对水源水质与胃肠道疾病进行拟合是可行的。
目的：探討水源水質與胃腸道疾病之間的關繫,以及胃腸道疾病的髮病規律。方法選擇淮安市2006年1月至2013年12月間水源水質指標及胃腸道患病例數,併進行相關性分析,然後進行具有輸齣時延反饋的非線性自迴歸(NARX)神經網絡模型的構建、訓練及模擬。結果水源水質的石油類、揮髮酚、總砷、總汞、6價鉻、氟化物及糞大腸菌群等指標與髮病人數有顯著的相關性。經過訓練後NARX神經網絡的可決繫數為0.716,擬閤效果比較理想。結論水源水質與胃腸道疾病之間存在一定的相關性,基于 NARX 神經網絡對水源水質與胃腸道疾病進行擬閤是可行的。

Objective To discuss the relationship between water quality and gastrointestinal diseases, and variation of gastrointestinal diseases. Methods Data of water quality indicators and gastrointestinal cases in Huai’an from January 2006 to December 2013 were collected. Correlation analysis was made and the NARX model was built, trained and simulated. Results Petroleum, phenol, total arsenic, total mercury, hexavalent chromium, fluoride and fecal coliform had a significant correlation with the gastrointestinal diseases. The coef-ficient of determination after the NARX neural network training was 0.716, and the fitting effect was perfect. Conclusion There was a certain correlation between water quality and gastrointestinal diseases. Fitting of water quality and gastrointestinal diseases based on nonlinear autoregressive neural network with external input was feasible.
