摘　　要：城乡建设统计工作是一份由上至下的工作。在污水行业,《中国城乡建设统计年鉴》《重庆市住房和城乡建设系统统计年鉴》的统计指标体系基本一致,均通过直接指标和间接指标等多指标维度统计了城市污水行业发展情况,但现行统计指标仍存在难以体现污水设施与城市开发建设的关系、污水收集处理系统能效体现不足及行业发展导向性不足等突出问题。为进一步指导污水行业良性发展,反映污水系统客观实际,按照“匹配性、成效性、导向性”的原则,以《重庆市住房和城乡建设系统统计年鉴》为例,对现有统计指标体系提出了“4+5+7”的优化增补建议,包含人均综合污水产率、供排匹配度、干污泥产率、建成区排水管网密度4项匹配性指标,有效排水许可证办件率、污水厂进水浓度、污水厂尾水浓度、污水管网运维单价、污水设施运维单价5项成效性指标,污水厂单位碳排放量、污水厂单位能耗、污水厂单位药耗、污水厂单位水耗、再生水利用率、污水冷热资源利用率、污水生物质能利用率7项导向性指标,并通过统计分析对部分关键指标特征值进行了研究。“4+5+7”优化建议也可为全国污水行业统计工作提供优化建议参考,为管理人员和规划设计人员提供参考,为下一步深入推进污水系统提质增效提供支撑,有利于提升全国城市污水系统统计水平及数据应用。The statistical work of urban and rural construction system is a nationwide work from both nation level and local level.Statistical Yearbook of Urban-Rural Construction in China and Chongqing Statistical Yearbook of Housing and Urban Rural Development System have similar statistic indices for urban wastewater systems,statedas multiple direct and indirect indices.But those indices have had difficulties in directly stating relationships between urban wastewater systems and urban developments and showing the effectiveness of collection and treatment,as well as lacking of any orientation significance for further improvements.To achieve sustainable development,to indicate the actual effectiveness of urban wastewater water collection and treatment,this research had brought out“4+5+7”strategy under the principle of“compatibility,effectiveness and orientation”for optimizing current statistical indices.There had been 16 indices adviced in total,including comprehensive wastewater water yield per capita,compatibility of supply and wastewater water,dry sludge yield,density of drainage pipe network in urban area as 4 compatibility indices,ratio of valid drainage permit application,influent concentration of wastewater treatment plants(WWTPs),tail water concentration of WWTP,unit price of wastewater pipe network for operation and maintenance,unit price of wastewater facilities for operation and maintenance as 5 effectiveness indices,carbon emission of the WWTPs by unit,energy consumption of the WWTPs by unit,drug consumption of the WWTPs by unit,water consumption of the WWTPs by unit,utilization rate of renewable water resources,utilization rate of wastewater cold and hot resources,utilization rate of wastewater biomass energy as 7 orientation indices.Then this research had analyzed the key characteristic values of significant advised indices.“4+5+7”strategy could be potentially helpful for statistic work of urban wastewater systems nationally,helping administrative staffs and planning designer for a better understa
