随着高速公路的建设和机动车辆的持续增长,高速公路对周边环境的影响越来越大 。以南京禄口机场高速公路沿线为研究对象,调查分析了距公路不同距离林地和荒地土壤的黑碳含量。结果表明:黑碳的集中扩散范围主要在高 速公路沿线50m内;林地和荒地土壤黑碳含量都表现为表层(0～10cm)的值高于表下层(10～30cm)的值,土壤黑碳主要集中在0～10cm的表层土中; 在10m处林地土壤的黑碳含量高于荒地的值,20、50m处土壤黑碳含量都是荒地的高于林地的值,林带对黑碳的扩散有一定的屏蔽吸收效果,可以减 少汽车尾气排放的黑碳对周围环境的影响范围。
Abstract
With highway expanding and motor vehicle increasing, the influence of highway is getting more and more significant to the surrounding’s environment. Soil black carbon characteristics of woodland and wasteland in different distance to the Nanjing Lukou airport highway were studied. The results revealed that soil black carbon content decreased with the increasing of site distance to the highway. The diffuseness range of black carbon mainly accumulated in 50m beside the highway. Soil black carbon content of surface layer (0—10cm) in woodland and wasteland were higher than that in deeper layer (10—30cm). Black carbon mainly accumulated in surface layer soil(0—10cm). At 10m to the highway, soil black carbon of woodland was higher than that of wasteland, but lower than that of wasteland at 20m and 50m to the highway. This indicated that the forest belts had certain shield absorption effects on black carbon diffuseness, and could reduce the pollution of black carbon dismissed by motor vehicle.
