【摘要】：為了解貴州喀斯特山地碳排放與碳固定的平衡狀況及其動態(tài)變化規(guī)律。利用2002~2012年貴州省能源消費量及植被面積等數(shù)據(jù),通過構(gòu)建數(shù)量模型,分析碳足跡、植被碳承載力和碳生態(tài)壓力指數(shù)等指標(biāo)的動態(tài)變化規(guī)律。研究結(jié)果表明:貴州省碳足跡總量由2002年的12 643.66萬噸上升到2012年的35 153.63萬噸,增長幅度為278.03%,年均增長16.18%,其中化石能源消費的碳足跡占總碳足跡的84.35%~93.78%,表明化石能源消費是導(dǎo)致碳足跡增長的主要因素。同期植被碳承載力從2002年的8988.83萬噸上升到2012年的15 032.65萬噸,增長幅度為67.24%,年均增長6.11%,其中森林固碳量76.94%~85.63%,園地固碳量占11.79%~21.00%,農(nóng)作物僅占1.90%~3.48%,揭示森林的固碳量最高。2002~2012年碳赤字呈現(xiàn)出上升的趨勢,由2002年的3654.83萬噸上升到2012年的20 120.98萬噸;碳生態(tài)壓力指數(shù)由2002年的1.41上升到2012年的2.34,而單位GDP碳足跡表現(xiàn)出下降的趨勢,從2002年的10.17噸/萬元下降到2012年的5.13噸/萬元。分析結(jié)果表明貴州在碳減排方面的政策措施有一定成效,但碳排放與碳固定之間不平衡,碳循環(huán)的生態(tài)環(huán)境壓力有持續(xù)增加的趨勢。
[Abstract]:In order to understand the balance of carbon emission and carbon fixation and its dynamic change in Guizhou karst mountain area. Based on the data of energy consumption and vegetation area in Guizhou Province from 2002 to 2012, the dynamic change rules of carbon footprint, vegetation carbon carrying capacity and carbon ecological pressure index were analyzed by building a quantitative model. The results show that the total carbon footprint of Guizhou Province increased from 12 6.4366 million tons in 2002 to 35 1.5363 million tons in 2012. The growth range is 278.03, and the average annual increase is 16.18. The carbon footprint of fossil energy consumption accounts for 84.35 / 93.78 of the total carbon footprint, indicating that fossil energy consumption is the main factor leading to the increase of carbon footprint. During the same period, the carbon carrying capacity of vegetation increased from 89.8883 million tons in 2002 to 15 326500 tons in 2012. The increase range is 67.240.The average annual increase is 6.110.The forest carbon sequestration is 76.940.85.63. the forest carbon sequestration accounts for 11.790.21.00, and the crops only account for 1.900.3.48. it is revealed that the carbon sequestration deficit of the forest from 2002 to 2012 shows an upward trend, rising from 36.5483 million tons in 2002 to 201.2098 million tons in 2012; The carbon ecological pressure index increased from 1.41 in 2002 to 2.34 in 2012, while the carbon footprint per unit GDP showed a downward trend, from 10.17 tons / 10,000 yuan in 2002 to 5.13 tons / 10,000 yuan in 2012. The results show that the policies and measures on carbon emission reduction in Guizhou have some achievements, but the carbon emissions and carbon fixation are unbalanced, and the pressure on the ecological environment of carbon cycle is increasing continuously.
