摘要
湖南省高速公路建设迅速发展，而高速公路两侧土壤重金属污染问题日益突出。综述了高速公路两侧土壤重金属的污染现状及相关研究，深入探讨了高速公路及其运输对两侧农田土壤污染的特征和程度，提出了基于高速公路两侧绿化带的植物吸收，体现“前条后块，树草相间”设计理念的新技术，在充分利用高速公路资源推进全省经济发展和社会进步的同时，为湖南省高速公路的安全规划与建设和降低交通运输污染创新新思路，减少高速公路对周围生态环境的影响。
With great rapid development of highway construction in Hunan province, the heavy metal pollution of soil has increasingly become serious on both sides of highway. The situation of heavy metal pollution of soil along the highway and related research are firstly summarized, and then the characteristics of agricultural soil pollution by transportation along the highway and its pollution degree are deeply discussed , finally the design of green belt should follow the square after rectangular in shape, trees after grass in species concept is proposed , the new concept making full use of highway resources promote economic development and social progress, in the meanwhile creating new ideas of highway safety planning and construction and reducing transportation pollution and the impact on the ecological environment along the highway.
