摘　　要：为直观反映工业生产中水资源消耗情况,基于工业用水和排水数据,探析2001—2020年北京市工业分行业的耗水演变特征,选取影响工业耗水的相关指标构建工业耗水计算模型并率定模型参数。结果表明:随着产业结构调整和高耗水行业的逐步退出,北京市工业总耗水量呈现下降趋势,由2001年的7.10亿m^(3)/a减少到2020年的2.24亿m^(3)/a。基于所率定参数,工业分行业耗水多元回归结果R^(2)均大于0.75,利用2020年数据对模型进行验证,可知模型对各行业耗水的计算误差均小于10%,表明所建立的模型能较好地反映了北京市工业耗水情况。With the accelerating expansion of cities and the development of social economy,the shortage of water resources is gradually becoming an obstacle.For northern China,the shortage of water resources is more serious.Industry is the pillar of the national economy.In the rapid development process of industry,it consumes a lot of water resources at the same time.Facing the increasing pressure of industrial water use,scientific and reasonable analysis of the changing law of industrial water use and its driving factors is of great significance to promote the sustainable development of industry.Most of the current research focuses on the water intake and use in the industrial production process,and the research on industrial water dissipation is less,especially on the water dissipation of industrial sub industries.As an important part of urban water dissipation,industrial water dissipation refers to the water directly solidified in products and food during industrial production and transported out of the area and consumed in the process of production activities.The value is equal to the difference between industrial water intake and drainage,which can more intuitively reflect the water dissipation in industrial production.Beijing was taken as the study area,where the problem of water shortage is very prominent.39 industrial sectors in Beijing were screened and consolidated,and were reconsolidated into 9 departments according to industry similarity:Mining and dressing industry,Food industry,Textile clothing and furniture manufacturing industry,Papermaking printing and stationery manufacturing,Petrochemical industry,Metal smelting and products industry,Mechanical equipment manufacturing,Electricity,steam,hot water,gas,tap water production and supply industry,Other industries.Based on the principle of water balance,the evolution and structure of water dissipation in various industrial sectors were calculated and analyzed.By selecting the relevant indicators that affect industrial water dissipation and establishing the indust
