快速城市化和城市扩张引发了住区形态的变迁,但形态变迁与居民通勤能源消费关系还不明确,如何通过城市的可持续公共管理政策来控制城市住区形态变迁过程下通勤能源消费及其温室气体排放有着重要意义.以厦门为例,通过土地利用与交通耦合模型TRANUS的情景分析研究了住区形态的变迁对人口、工作以及土地消费空间分布的影响,进而分析了不同情景下通勤能源消费和温室气体排放的水平.结果表明:基准情景下交通出行早高峰能源消费总量为54.35 tce,CO2排放为119.12 t;住区形态变迁情景下,通勤能耗和CO2排放同比基准情景均增加12%;通过适当的土地利用、交通和经济政策的实施,通勤能源消费与CO2排放同比基准情景减少7%,说明城市公共政策能够有效地控制住区形态变迁背景下通勤能源消费和温室气体排放的增长.
Rapid urbanization and urban expansion lead to changes in the form of settlements. However, the relationship between form changes and residents’ energy consumption in commuting is unclear. How to control the commuting energy consumption under urban form change through urban sustainable public management policies? The greenhouse gas emission is of great significance.With Xiamen as an example, this paper studies the impact of the change of residential area morphology on the spatial distribution of population, work and land consumption through the scenario analysis of the land use and transport coupled model TRANUS, and then analyzes the influence of commuting energy Consumption and greenhouse gas emissions.The results show that the total peak energy consumption of traffic rush hour in the baseline scenario is 54.35 tce and the emission of CO2 is 119.12 t.Under the condition of residential area morphological changes, 12%; the year-on-year reduction of commuting energy consumption and CO2 emissions by 7% through the implementation of appropriate land use, transportation and economic policies, indicating that urban public policies can effectively control the commuting energy consumption and greenhouse gas emissions growth of.
