摘 要:交通产生的排放、粉尘、噪音等生态环境问题日益突出,公路交通对短距离区域内的生态影响较大。通过建立生态足迹模型测算长江上游地区公路交通的生态足迹和生态承载力,并从生态盈余/生态赤字的角度分析长江上游地区公路生态交通的演化。研究结果发现,公路生态足迹变化趋势有波动,公路生态承载力缓慢上升,生态盈余呈下降趋势;长江上游地区森林及建设用地面积和各交通方式客运量的变化对公路生态足迹的减少具有促进作用,而工业产值、公路货运量以及机动车保有量的变化促使公路生态足迹增加。The ecological environment problems such as emissions,dust,noise caused by traffic are becoming more and more prominent.Highway traffic has a greater impact on the ecology of short-distance areas.The ecological footprint and ecological carrying capacity of road traffic in upperstream of Yangtze River are measured by establishing an ecological footprint model,and the evolution of road ecological traffic in the upper Yangtze River is analyzed from the perspective of ecological surplus/ecological deficit.The results show that the ecological footprint of highways has fluctuated.The ecological carrying capacity of highways has slowly increased,and the ecological surplus has shown a downward trend.The changes in the area of forest,construction landand the passenger volume of various transportation in the Upper Yangtze River have the promoting effect to reduce the ecological footprint of highway,and changes in industrial output value,road freight volume and motor vehicle ownership have increased the road ecological footprint.
关 键 词:长江上游地区 生态公路 生态足迹 生态承载力 生态盈余
