备注

新区作为当前城市空间发展的重要形式,是探索低碳城市空间布局与模式的前沿实践地.以国家级新区为研究样本,利用出行方式距离与能耗系数法计算样本新区的交通出行碳排放量,并转化为人均、地均和产均碳排放强度,综合反映城市新区的出行碳排放水平,据此择取低碳新区的较优样本; 借助空间自相关和空间句法等方法构建关键指标,测度城市用地分布、道路网络、绿色开敞空间等要素,比较分析低碳新区样本的空间布局特征; 在此基础上从各类建设用地疏解、绿色开敞空间有机、道路系统高效等层面提出城市新区总体空间低碳化优化策略,为西部“一带一路”沿线城镇新区绿色发展与规划建设提供经验借鉴.
As an important form of urban space development at present, the new area is a frontier practice place to explore the spatial layout and mode of low-carbon cities. Taking the state-level new areas as the research samples, the travel mode and energy consumption coefficient method are used to calculate the traffic carbon emissions of the new areas samples, which are converted into carbon emission intensity per capita, per land and per GDP, comprehensively reflecting the travel carbon emission level of the urban new areas, and based on this, a better sample of low-carbon new areas is selected. With the help of spatial autocorrelation and spatial syntax, the key indices are constructed to measure the distribution of urban land use, road network, green open space and other factors, and the spatial layout characteristics of low-carbon new area samples are compared and analyzed. On this basis, the low-carbon optimization strategy of the overall space of the new urban districts is proposed from the aspects of various construction land dispersal, organic green open space and efficient road system, which provides experience for the green development and planning of the new urban areas along the Belt and Road in western China.
