“二氧化碳排放力争于2030年前达到峰值，努力争取2060年前实现碳中和”这一国家战略目标，不仅体现了我国作为世界大国的担当，也符合我国经济产业结构转型的需要。城市在我国人口、能源消耗、碳排放中均占据主导地位，是我国实现碳达峰、碳中和的主战场。文章首先指出城市能源系统在推进国家“双碳”目标中的重要角色及其面临的重要挑战。然后，以澳门为例分析城市能源消费、碳排放的基本特征。最后，提出“推广需求侧管理为主、利用分布式清洁能源为辅、主动外购绿电为补充、发展智能化技术为支撑”的城市实现碳中和的技术路径，为推动我国城市碳中和进程提供参考依据。 相似文献

In order to improve the effect of visual analysis of regional economy, this paper uses machine learning algorithms to analyze time series data, uses various models and methods of intelligent data analysis to mine data laws from huge data, statistical data reports, and find problems in economic development. Moreover, this paper combines the time series algorithm to design and plan the functional structure of the system, and design a separate module structure from the actual situation of regional economic analysis, and build a model system from the overall structure. After constructing the system, this paper tests the system. From the results of the experimental research, we can see that the regional economic visualization system based on time series constructed in this paper has perfect system functions and can meet the needs of regional economic analysis. 相似文献
