生态足迹的概念及计算模型

The Concept of Ecological' Footprints' and Computer Models

生态足迹是一种定量测量人类对自然利用程度的新方法。通过跟踪区域的能源和资源消费 ,将它们转化为提供这种物质流所必须的各种生物生产土地类型的面积 ,并同区域能提供的生物生产土地面积进行比较 ,能定量判断一个区域的发展是否处于生态承载力的范围内。介绍了生态足迹的概念及其计算模型 ,分析总结了模型的优缺点。

Ecological‘Footprints’ are a kind of new method of quantifiably measuring the extent of humanity's use of nature. Through following the tracks of consumption of energy and natural resources of a region, these consumption patterns provide information of areas, showing each type of land necessary for providing these material resources. Through comparison of these different areas providing natural resources, we can quantifiable judge the scope within which that area's capacity to provide can be developed. Here we give an introduction to the concept of ecological ‘footprints’ and computer modeling, as well as analyzing and summarizing the strong and weak points of such a model.
