低碳城市的城市形态和能源愿景

本文提出人均碳排放量、地均碳排放量、单位GDP碳排放量和人类发展指数4个指标可以作为我国低碳城市的评价指标。在特定的经济结构、能源结构、城市化水平和资源条件下,国外建设低碳城市的经验和示范并不完全适合中国国情,中国必须探索自己发展低碳城市的道路。中国低碳城市的城市形态主要特征是"紧凑型城市",即高密度(Highdensity)、高容积率(High plot ratio)和高层(High rise)的3"H(高)"城市。而低碳城市的能源规划目标应该是实现3"D",即使用低碳能源(Decarburization)、分散产能(Decentralization)和减少需求(Demand reduction),并应分别在城市、区域和终端用户3个层面实现3"D",其中终端用户节能被视为一种无碳的虚拟能源。另外,本文简要介绍了"能源总线"和"能源互联网"这2种在低碳城市建设中很有发展前景的能源系统。

Urban Form and Energy Vision in Low-carbon Cities

In this paper,the per capita carbon emissions,per unit domain area carbon emissions,per unit GDP carbon emissions and local human development index(HDI) were proposed,which were used as four indicators for the evaluation index of China's low-carbon city.Under the particular economic structure,energy structure,the level of urbanization and resource conditions,the construction and demonstration experience of foreign countries would not be fully suited to China's situation.China must find her own roadmap of lo...
