由于城市工业用水量占城市总用水量的2／3，城市工业总产值也占全国国民经济总产值的80％，所以预测城市工业用水量对城市经济的发展，解决缺水问题，采取节水措施是至关重要的，根据我国某城市的工业用水统计资料，采用龚帕兹模型y＝e(k+ab’)，或lny＝k十ab’进行预测，取得了较为满意的结果，并对成果进行了分析，这对指导城市经济建设和产业结构的调整具有重要的指导意义。
As urban industrial water consumption accounts for two-thirds of the total urban water consumption, and the total industrial output value of the city also accounts for 80% of the national total economic output value, the urban industrial water consumption is expected to contribute to the development of the urban economy, solve water shortages, and adopt water conservation. Measures are crucial. According to the statistical data on industrial water in a certain city in China, the Gompertz model y=e(k+ab’), or lny=k10 ab’, is used for prediction and satisfactory results are obtained. The analysis of the results has important guiding significance for guiding the economic construction of the city and the adjustment of the industrial structure.
