摘要
生态足迹是评价区域可持续发展的定量方法,也是一种用来度量人类活动对生态系统压力和影响的新途径。扬州市生态足迹计算的结果显示,2010年为2.823hm2/人,是本地区生态承载力的5.39倍。扬州市生态赤字高于全国平均水平,并主要通过资源输入进行弥补。经济发展的生态转型和城镇建设的低碳化是抑制生态足迹过快增长的关键,实施区域生态保护有助于提高生态承载力。
The concept of the ＂Ecological Footprint＂ （EF） is used to quantify the sustainability of the area development. It permits estimation of the pressure and impact of human activities on ecosystems. This study calculated the EF of Yangzhou city in 2010. The EF of Yangzhou is 2. 823 hectares per capita, which is 5.39 times than this city＇s biD-capacity. The ecological deficit of Yangzhou is higher than the average level of China. The deficit is made up by the resource input. The ecological transformation of economic development pattern and the construction of low carbon urban are crucial to the reduction of the EF over-inerease. On the other hand, the implement of eco-reservation will held to the bio-capacitv increase.
