面向空间使用活动数据的城市建成区碳核算方法研究——以黑龙江省哈尔滨市为例

Study on Carbon Accounting Methods in Urban Built-up Areas Using Spatial Activity Data:A Case Study of Harbin,Heilongjiang Province

气候变化是全世界正在面对的重大威胁,实现碳达峰、碳中和目标已成为中国重要的城市发展战略。碳核算是监测城市碳排放情况,调控低碳城市建设的重要技术手段。以城市建成区为碳核算范围,并将城市碳核算方法与城市空间要素相衔接,这对于实现城市“双碳”目标发展具有极强的现实意义。以黑龙江省哈尔滨市为研究对象,总结分析其15年间的能源活动数据与空间使用活动数据,构建城市建成区碳核算体系与面向城市空间使用活动数据的城市建成区碳核算方法,并将核算结果与能源使用碳核算结果进行对比,验证核算方法的准确性。在此基础上,提出构建城市碳中和路径预测、开展低碳城市建设专项评估等碳核算方法应用路径,为国土空间规划助力“双碳”目标的实施提供技术支撑。

As climate change emerges as a significant global threat,achieving the goal of carbon peak and carbon neutrality has become a crucial strategy for urban development in China.Carbon accounting serves as a vital technical tool for monitoring urban carbon emissions and regulating low-carbon urban construction.Focusing on the urban built-up area,this study integrates urban carbon accounting methods with urban spatial elements,holding great practical significance for realizing the development goals of"dual carbon"cities.Taking Harbin City,Heilongjiang Province,as the research object,this paper summarizes and analyzes fifteen years of energy activity data and spatial usage activity data to establish an urban built-up area carbon accounting system.Furthermore,it develops a method for urban built-up area carbon accounting based on urban spatial usage activities and compares the accounting results with those of energy usage carbon accounting to validate the accuracy of the accounting method.Based on these findings,pathways for urban carbon neutrality prediction and specialized assessments for low-carbon urban construction are proposed,providing technical support for the implementation of the"dual carbon"goals in national territory spatial planning.
