Measure of sustainable development of Suining national eco-demonstration area
绥宁县国家级生态示范区可持续发展度量探析

The measure of sustainable development of Suining national eco-demonstration area was studied. The results show that the ecological footprint per cap. was 1. 517888hm^2, the ecological carrying capacity was 1. 286877 hm^2 and the ecological deficit was 0. 231011 hm^2 in 2001 ,showing that the social economy of Sulning County was not sustainable. But after eco- demonstration area construction, the ecological footprint will be 1. 343577 hm^2, 1. 328835 hm^2 , the ecological carrying capacity 1. 320071 hm^2, 1. 423893 hm^2 ; the ecological surplus 0. 023506 hm^2, 0. 095058 hm^2 ; the ecological footprint per 10000 yuan GDP 2.46 hm^2 ,0.83 hm^2 ;the ecological carrying ratio 0.98,1.07 in 2005 and 2015 respectively. The ecological deficit and ecological footprint per 10000 yuan GDP become decreasing, the ecological carrying ratio becomes increasing and reaches about 1 after eco-demonstration area construction, which makes resources utilization and energy constructure optimization, social economy becomes sustainable.
