Forecast and Treatment Model of Construction Waste——A Case Study of Liuzhou
Based on the analysis of the construction waste output and disposal cost data of Liuzhou in the past 11 years(2012-2022),this paper uses the single sequence and one stage linear differential equation model GM(1,1)in the grey model to predict the construction waste output and disposal cost of Liuzhou in the next five years,and proposes the local-centralized resource treatment model.The research shows that:① China's construction waste has the characteristics of huge production,rapid growth,mainly construction demolition waste,and uneven re-gional distribution;② The posterior difference ratio C value of the gray dynamic GM(1,1)yield prediction model was 0.076≤0.35,and the maximum relative error value was 0.058＜0.1,which showed that the fitting effect of the model met high requirements;③ It is predicted that the output of construction waste in Liuzhou will be 532108300 cubic meters in five years,about 40 times that of 2022,and the disposal fee of 189670600 yuan will be about 3 times that of 2022.
