利用曲线拟合的方法建立了空气中PM 25．浓度以及质量的预测和评价的高斯扩散模型。模型考虑了数据相对于风力、湿度、时间的变化情况、数据之间存在着相互联系，对未来西安市PM 25．的情况进行了合理的预测。通过曲线拟合和非线性回归并利用统计软件SPSS ，数学软件MATLAB、1stOpt 15．以及绘图软件Sufer进行编程计算，给出了问题的解答：西安地区PM 25．的浓度从一月到四月逐渐降低。对西安市13个监测点四个月的PM 25．的浓度分区进行了初步污染评估：小寨和临潼区属于中度污染区；高压开关厂、兴庆小区和纺织城等9个监测点属于重度污染区；高新西区和草滩属于严重污染区。
利用麯線擬閤的方法建立瞭空氣中PM 25．濃度以及質量的預測和評價的高斯擴散模型。模型攷慮瞭數據相對于風力、濕度、時間的變化情況、數據之間存在著相互聯繫，對未來西安市PM 25．的情況進行瞭閤理的預測。通過麯線擬閤和非線性迴歸併利用統計軟件SPSS ，數學軟件MATLAB、1stOpt 15．以及繪圖軟件Sufer進行編程計算，給齣瞭問題的解答：西安地區PM 25．的濃度從一月到四月逐漸降低。對西安市13箇鑑測點四箇月的PM 25．的濃度分區進行瞭初步汙染評估：小寨和臨潼區屬于中度汙染區；高壓開關廠、興慶小區和紡織城等9箇鑑測點屬于重度汙染區；高新西區和草灘屬于嚴重汙染區。

This article was built with the method of curve fitting and PM 2 5. concentration in the air quality prediction and evaluation of Gaussian diffusion model .In the model ,account was taken into the data relative to the change of wind ,humidity ,time ,existing interconnected data ,the reasonable forecast to PM 2 5. of Xi'an in the future has carried on .In this article ,through curve fitting and non‐linear regression and the use of the statistics software SPSS ,mathematical software MATLAB ,1st Opt 1 5. and drawing software Sufer programming calculation ,the solution of the problem was given as follows :the concentration of PM2 5. in Xi'an region gradually reduces from January to April ,the preliminary evaluation of 13 monitoring stations of Xi'an ,four months PM2 5. pollution concentration zoning was carried on :Xiaozhai and Lintong districts were attributed to moderate pollution areas ;High voltage switch factory ,Xingqing district and Textile city belong to high level of pollution of the nine monitoring areas ;Western high-tech zone end and Grass land belong to the serious pollution ar‐eas .
