摘要
采用三维生态足迹模型,以“省公顷”为计量单位,结合ArcGIS测度青海东部城市2010~2017年人均生态足迹深度与生态足迹广度。结果表明:青海东部城市在2010~2017年间,牧草地、林地、水域资本流量一直被完全占用,人均足迹深度远大于1,仅能通过消耗大量资本存量维持物资需求,因此青海东部城市处于不可持续发展的态势。为维护城市生态环境稳定,从如何保护土地的绿色发展、新能源的研发与使用、建立资源节约型社会、国土空间规划与人居环境建设这四个方面提出建议。
A three-dimensional ecological footprint model was used,with"provincial hectares"as the unit of measurement,combined with ArcGIS to measure the per capita depth and breadth of ecological footprint of eastern Qinghai cities from 2010 to 2017.The results show that during the period 2010 to 2017,the capital flows of pastures,woodlands,and waters in the eastern cities of Qinghai have been fully occupied,and the per capita footprint depth is far greater than 1,which can only sustain the material needs by consuming a large amount of capital stock.So the eastern cities of Qinghai are unsustainable development of the situation.In order to maintain the stability of the urban ecological environment,suggestions are made from four aspects of how to protect the green development of land,the research and development and use of new energy,the establishment of a resource-saving society,national land spatial planning and the construction of human settlements.
