摘　　要：首先以建筑面积核算法对济南市2000~2017年建筑废物产量进行了估算,然后以估算值作为原始数据,建立了灰色GM(1,1)预测模型.最后对未来5a济南市建筑废物产量进行了预测.经验证,模型精度等级达到优秀级.结果表明,灰色GM(1,1)预测模型可以准确地预测济南市建筑废物的年产量,预测表明济南市建筑废物平均产量将从2018年的860万t,增加到2022年的1000万t.The construction waste residue generation in Jinan City,China from 2000 to 2017 was firstly assessed based on the method of building area estimation,GM(1,1)model was then created with the estimated value as the original data.Finally,we applied our model to predict the output of construction waste generation in Jinan in the next five years.Validation results showed the accuracy of the model was excellent.The results indicated that the GM(1,1)model could accurately forecast the annual output of the construction waste residue in Jinan,the projected waste would increase to 10 million tons per year in 2022 from 8.6 million tons per year in 2018.
