| Related literatures about ecological fragile is reviewed; the current status of ecological environment in the upper Min River basin is summarized. Equations for calculating the ecological footprint and ecological carrying capacity, as well as the standards of evaluating the status of ecological security are introduced. When ecological carrying capacity is greater than ecological footprint, ecosystem in this region is in safe state, and vice verse. According to the research data about five counties in upper Min River Basin, ecological footprint per capita and ecological capacity per capita are calculated in upper Min River Basin. Result shows that ecological system is in safe state in general. Interference of human activities on natural ecosystem has not... |

| According to the 2000-2010 Jiangsu Statistical Yearbook, per capita ecological footprint and per capita ecological carrying capacity in Jiangsu Province in the years 2001-2009 are analyzed starting from the ecological footprint model. Per capita ecological deficit is measured, as well as the pressure index of ecological footprint in order to judge the grade of ecological security and to objectively evaluate the ecological security of Jiangsu Province. GM(1,1) grey forecasting model is used to forecast the ecological security of Jiangsu Province in the years 2010-2014. Research shows that in the next 5 years, both the per capita ecological footprint and the pressure index of ecological footprint will increase by 4% and 3.7% each year, respectively. And the... |
