Illuminated by the mechanical system of the movement of matters, it comes up that ecological footprint based on consumption of biologic production could not tell whether the ecological pressure acts on the specified region, and the original ecological footprint theory also undervalued the development impartiality of a region. A modification on this theory is made by introducing consumptive ecological footprint and productive ecological footprint, in which the latter is taken as the indicator of regional sustainability. The development impartiality can be demonstrated by comparison between the global ecological deficit per capita and regional consumptive ecological deficit per capita.展开更多

It translates production into biologically productive areas offering material flows to measure the utilized degree of nature by humankind. At present, China runs ecological deficits because footprints required for consumption are larger than available ones. In the paper, the ecological footprint model is applied to calculate the deficits by resource, environment and import-export accounting. It is clear that the deficits have caused enormous pressure to resource and environment, which would become bigger with more factors of resource and environment being accounted. In the primary production and energy trade, import footprint turned from deficit to surplus after 1996, which benefited the conservation of national resource. But compared with the huge depletion caused by resource and environment, they had small effects on deficits.展开更多

At last, it can be identified that ecological footprint is a good method to measure resourceutilization and environmental pollution in various subsystems of an integrated ecological industry.展开更多
