Abstract:

The karst mountainous area is undeveloped, ecological environment is weak and sensitive; accurate evaluation of carbon emissions of agriculture and energy consumption of the karst mountain area has important meaning to regional carbon accounting. According to reference research, with the aid of the theories of ecological footprint, the author changed resources consumption into land area, and calculated carbon emissions of resources consumption use by coefficient of carbon emissions transform indirect in 2008. The result showed that: (1) the total carbon emission of biological resources consumption (crops) of Bijie was 535960.68 t in 2008, per capita carbon emission was 0.0643 t and unit area was 0.1996 t/km2; carbon emissions of energy consumption such as coal, natural gas and fuel were 30058347.94 t, 1707.766204 t, 18956.56547 t, respectively, per capita carbon emissions were 3.6046 t, 0.0002 t, 0.0023 t and unit area of carbon emissions were 11.1937 t/km2, 0.0006 t/km2, 0.0071 t/km2; (2) The coal consumption was mainly carbon emissions in Beijie Region, the coal consumption carbon emission accounted for 99.9% of carbon emission of the energy consumption. (3) Per capita and unit area carbon emissions in Bijie were much higher than the national average. (4) The carbon sink (solid carbon) effect in Bijie was poorer, the main reason is that forest coverage rate was low, caused by the rocky desertification (human destruction), the second reason was the karst background. Exploring carbon emission of typical karst area based on the resource consumption could not only perfect our country’s carbon emissions theory, but also provide helpful reference for countries to make different regional carbon emission targets and control policies.
