【摘要】 随着中国城市化进程的加块,城市能耗和由此带来的碳排放量越来越高。目前对城市节能减排研究的焦点主要集中在城市各项子系统的节能,而对子系统之间的相互影响研究不足。通过城市空间规划的策略来控制城市物质形态,可以优化城市子系统,以达到节能减排的目的。这些策略主要可分为两类:一类是通过优化城市空间减少能源的需求,另一类是通过优化用能单位的布局提高能源利用效率。在南京河西南部地区城市设计以及生态城市建设导则中对这些策略进行了具体应用。更多还原

【Abstract】 Much energy is consumed and carbon emission is released by cities.The carbon emission will keep in increasing with the urbanization in China.Current research about energy efficiency of cities mainly focused on energy efficiency of city subsystems,but less on their interactive influence.To measure energy efficiency carbon dioxide emission should be introduced as an indicator.Urban planning is a preferred method for energy efficiency of cities by adjusting city forms and the relationship between city subsystems.The strategies of urban planning can be classified at two sets: decreasing the energy demands of cities and increasing the efficiency of energy utilization.The strategies to reduce the energy demands can also be subdivided into reducing building energy consumption and reducing transportation energy consumption.The strategies were practiced at the urban design for the south region of Hexi New City District,Nanjing,and the guidelines for environmental construction in the new city district,which will be an example for the new urban construction in the fast urbanized China.更多还原
