中文摘要：

为了定量评价道路立交部的交通污染状况,根据可拓学的理论和方法,选取当量空气污染、当量噪声污染、影响系数共3大类12个指标,建立了基于可拓的道路立交部交通污染评价模型.以黑龙江省鹤大立交为例进行研究,应用可拓学理论可以对道路立交部交通污染进行评价,为从环境保护角度优选立交方案提供定量依据.

英文摘要：

To valuate the traffic pollution quantitatively of the segment of road interchange, twelve indexes of three categories including equivalent air pollution, equivalent noise pollution and influence coefficient were studied by using the theory and method of extenics, then a traffic pollution evaluation model of the road interchange was established. Heda interchange in Heilongjiang province was investigated as an example. The result shows that the extenics method can quantitatively evaluate the traffic pollution of the segment of road interchange, and it can provide a reference for choosing the best interchange scheme from the view of environmental protection.
