城市粪便清运处理系统的数量特征和预测

Numerical Characteristics and Prediction of Night soil Treatment System in Cities

根据建设部《城市建设统计年报》（１９７９～１９９４）、抽样调查以及有关文献，通过数据处理、相关回归分析、方差分析和直观图表，研究了我国粪便清运量和机械化清运率、粪便处理设施和能力等的时间变化与其它因素的相关性，并对城市粪便处理系统的发展作了预测．

Depending on The Statistical Almanac of Urban Construction(1979-1994)and other referencs,more data are statistically treated.By correlation regression analysis,variance analysis and statistical charts,the chronological changes and their relations with other factors of the nigth soil cleansing amount,the proportion of night soil mechanic cleansing,night soil treatment facility and capability are studied and the development of the night soil treatment system in cities of China is also predicted.
