基于城市微观土地利用影响下的碳排放评测研究——以南京市某单位为例

文章借助连续逼近法与交通周转量法构建城市微观土地利用影响下的碳排放评测模型,并依据该模型对南京市某单位双园区土地利用模式所带来的碳排放进行了评测。结果表明：（1）不同交通方式下的碳排放量不同,城市公交交通方式年碳排放量最低,为203008.80kg;私人轿车交通方式年碳排放量最高,为659398.01kg。（2）同一交通方式下,不同等级车型的碳排放量相同。单位通勤交通方式中,中型客车〉大型客车〉轻型客车;私人轿车交通方式中,中级轿车〉普通轿车〉微型轿车。据此定量化城市微观土地利用与碳排放的关系,为土地利用配置过程中碳减排的研究提供参考。

Research of Urban Microscopic Land-utilization Influence on Carbon-emission Evaluation——A Case Study on a Unit in Nanjing

This paper established a carbon-emission evaluation model with the aid of the continual approximation and traffic turnover. Based on this model, the carbon-emission had been evaluated brought by the double campus land utilization pattern of a unit. The result shows that ： 1 ） by the comparison of four different kinds of traffic situations, the carbon-emission of urban public transportation is 203,008.80 kg, the lowest. The carbon-emission of private car transportation is 659,398.01 kg, the highest; 2） in the identical transportation, the different vehicle types, regarding the carbon-emission＇s influence is also various. In the unit commuting transportation, the carbon-emission order of rank decrease is ： medium passenger train 〉 largescale passenger train 〉 light passenger train; in the private car transportation, the order of rank decrease is： intermediate private car 〉 ordinary private car 〉 miniature private car. So it can be used to quantitative the relationship of urban microscopic land-utilization and carbon-emission, and propose some measures on the researches of carbon-emission under the urban microscopic land-utilization influence.
