摘要
以上海市某区为例,对上海城市生活垃圾收集点垃圾产生量的概率分布进行研究。通过调研得到原始数据,运用matlab软件统计函数对调研数据进行分析处理,得到数据的频数直方图、概率密度图和正态概率图,并初步判定数据服从正态分布。运用非参数检验中的正态分布检验KS检验方法,在显著水平0.05的情况下,对图像观察判定结果进行检验,最终验证数据近似服从正态分布,并通过计算变异系数得到数据的稳定性。运用3Sigma原则给出了该区域垃圾产生量的分布范围,可对研究区域的垃圾产生量分布情况做进一步的研究,为生活垃圾的收运工作合理安排提供理论依据。
Taking a district of Shanghai as an example,we studied the probability distribution of municipal solid waste（MSW）production in collection points in Shanghai. Through the investigation and research,the original data were obtained,and the research data were analyzed and processed by using Matlab statistical function. The frequency histogram,probability density graph and the normal probability graph of the data were given. The data was initially judged to be normal distribution.The KS test of the nonparametric test was used to test the normal distribution. In the case of a significant level of 0.05,the results of observation and judgment for the image were checked,the final validated data approximately obeyed the normal distribution,and the data stability was obtained by calculating the coefficient of variation. The 3 Sigma principle was used to give the distribution range of MSW production in this region. O n this basis,the distribution can be further studied,and it can provide a theoretical basis for the reasonable arrangement of MSW collection and transportation.
