一种生态足迹的地理可视化方法——以湖北省为例

A Geographical Visualization Method for Ecological Footprints——A Case Study of Hubei Province

  • 摘要: 生态足迹作为衡量地区可持续发展的重要方法与手段,可以定量地分析研究区域的生态盈亏状况。现研究多为回顾性分析或时间序列分析与预测,少有生态足迹地理空间分布的研究。随着遥感技术的发展,丰富的遥感产品提供了更加精细的尺度研究生态足迹的可能性。在GIS的支持下,基于人口密度分布数据、夜光影像与MODIS产品,提出一种在公里格网尺度研究生态足迹的方法,并提出“产出型”生态足迹与“消费型”生态足迹两种在公里格网尺度描述生态足迹空间分布的新方法。在估算了2010年湖北省生态足迹的基础上,分析了湖北省生态足迹的空间格局。

     

    Abstract: Ecological footprints, as an important method and means to measure regional sustainable development, can quantitatively analyze and study the ecological profit and loss of the region. The current researches are mostly retrospective analysis or time series analysis and prediction, and few studies have been conducted on the geographical and spatial distribution of ecological footprints. With the development of remote sensing technology, abundant remote sensing products provide the possibility of studying ecological footprints at a more detailed scale. With the support of GIS, based on population density distribution data, noctilucent images, and MODIS products, this paper proposed a method to study ecological footprints at the kilometer grid scale, and also proposed two new methods to describe the spatial distribution of ecological footprints at the kilometer grid scale: "Output-type" ecological footprint and "Consumer-type" ecological footprint. Based on the estimation of the ecological footprint of Hubei province in 2010, analysis was made of the spatial pattern of the ecological footprint of Hubei province.
