A Research into Ecological Footprint in Nanjingl

Ecological footprint is a new way to quantitatively survey the degree of human being's use of nature. On the basis of a simple introduction to its theory and method, this paper conducts quantitative studies of per capita ecological footprint and per capita ecological load-bearing capacity during 1992-2001 in Nanjing. The result shows a serious deficit of ecological footprint. Moreover, this deficit has been increasing year after year. In accordance with pertinence, the paper builds a regression model of ecological footprint and per capita GDP, level of material utilization, and predicts the ecological footprint during 2002-2006 in that city.
