摘要
根据西安市过去若干年生活用水量的统计资料,分别采用一元线性回归、生长曲线、GM(1,1)灰色系统模型和人均综合生活用水定额法对西安2010年、2015年城市生活需水量进行预测,并对各种方法的预测结果进行分析比较,认为生长曲线模型的预测结果比较合理,确定了西安2010年、2015年城市生活需水量范围。
Based on the statistic data of domestic water comsumption of Xi＇an in the past 10 years, linear regression model,growth curve model,grey system model and average domestic water corisumption quota per capita method are adopted to forcast the domestic water demand of 2010 and 2015 in Xi＇an. By analyzing and comparing the results ,the result of growth curve is rational and the range of the domestic water demands of 2010 and 2015 in Xi＇an are predicted.
