中文摘要：

道路交通对城市碳排放的影响举足轻重，其碳脉研究则是城市碳控的重要路径。基于偏最小二乘法对无锡市城市道路交通的碳脉，特别是碳转化系统中“脉络盲区”的碳脉驱动要素矢量进行了研究。结果表明，人均道路面积、机动车数量与人口数量是影响城市交通碳转移的主要因素，GDP和居民可支配收入在城市交通碳转移中的地位举足轻重，公交车日均载客量、车辆总数和客货运周转量对城市交通碳转移的影响水涨船高，科研投入对城市交通碳转移的贡献有待提高。从高起点布局智慧城市的邻里设计，高标准推动低碳交通的技术创新，高规格聚合低碳交通的管理工具，高要求构建道路交通的“倒三角”体系等方面提出了城市道路交通碳脉优化的可行性措施。

英文摘要：

We couldn＇t ignore the important effect that road transportation had on the urban carbon emission. The research on carbon pulse played an important role on the path of city＇s carbon control. This paper studied the carbon pulse of urban road transportation in Wuxi based on the PLS,especially analyzed the driving elements of carbon pulse in carbon conversion system＇s ＂pulse blind area＂. The result of empirical analysis showed that the road area per capita, the number of motor vehicles and population were the main factors to the urban traffic carbon transferring, GDP and the income of residents had an increasing effect on the urban traffic carbon transferring, the average daily patronage of buses, the bus number and the freight turnover indicated a far- reaching significance to the urban traffic carbon transferring which couldn＇t be ignored, and the technology invest- ment＇s contribution to the urban trat~c carbon transferring remained to be improved. Therefore, this paper put forward feasible measures to optimize the carbon pulse of urban road transportation from arranging the neighborhood - design of wisdom city at high starting point, promoting the technological innovation of low - carbon traffic on high standards, aggregating the management tools of low - carbon traffic at high specification, and constructing the ＂inverted triangle＂ system of road traffic at high requirement.
