- Abstract:
-
Ecological footprint model and material flow analysis were used to analyze and evaluate Shijiazhuang ecological footprint and sustainability metabolic material flow from 2002 to 2011. The results showed that: (1) in the study period, Shijiazhuang City, the per capita ecological footprint overall presented the upward trend, it reached up to 6.964 207 hm2/person in 2011, per capita ecological carrying capacity decreased from 0.251 515 hm2/person to 0.213 777 hm2/person, ecological deficit was significant during this period, and the per capita ecological deficit had reached to 6.750 43 hm2/person in 2011, these showed that use of natural resources in Shijiazhuang City was beyond the scope of ecological carrying capacity, and ecological development was not sustainable; (2) overall direct material input of Shijiazhuang City presented increasing trend from 5.77×108 t in 2002 to 7.54×108 t in 2011, regional resource extraction activities were growing with resource dependencies, and resource development was also more extensive, the hidden region stream (DHF) had become the major source of environmental stress; (3) compared to that in 2002, material productivity (MP) increased by 1.78 times in 2011, the data showed its effectiveness in substance use had improved, but the use efficiency of resource was still low.
