摘要
[目的]分析新疆塔城地区1980—2020年的碳排放变化时空特征及效应,为科学制定区域碳减排措施及低碳调控政策提供依据。[方法]基于1980—2020年土地利用变化数据,计算了塔城地区碳排放量和碳吸收量,并采用碳足迹和碳生态承载力评估了碳排放效应。[结果](1)1980—2020年,塔城地区净碳排放量表现出明显的增加趋势,其中耕地和建设用地的不断扩张是导致塔城地区碳排放量增加的主要诱因,而林地面积的持续减少是造成塔城地区碳吸收量减少的关键因素;(2)在空间分布上,沙湾县和乌苏市是塔城地区的主要碳源区,解释了塔城地区净碳排放的67.20%,和丰县和额敏县解释了塔城地区净碳排放量的20.89%,托里县是塔城地区的主要碳汇区;(3)在碳排放效应方面,2000年前塔城地区绝大多数区域都表现为生态盈余,但2000年后开始出现碳排放的生态赤字。[结论]当前,沙湾县、乌苏市及和丰县,存在明显的生态赤字,是未来塔城地区碳减排的重点控制区域。
[Objective] The temporal and spatial characteristics and effects of carbon emission changes in the Tacheng area of Xinjiang Uygur Autonomous Region from 1980 to 2020 were analyzed in order to provide the basis for formulating regional carbon emission reduction measures and low carbon regulation policies.[Methods] The spatio-temporal changes of carbon sources,carbon sinks,and carbon emissions based on land use changes from 1980 to 2020 in Tacheng area was analyzed,and the carbon emission effects were evaluated using carbon footprint and ecological carbon carrying capacity.[Results](1) Net carbon emissions in the Tacheng area showed an obvious increase from 1980 to 2020,during which the continuous expansion of cultivated land and construction land area was the main factor leading to the increase in carbon emissions,and the continuous reduction of forest area was the main factor leading to the decrease in carbon absorption;(2) In terms of spatial distribution,Shawan County and Wusu City were the main carbon sources,accounting for 67.02% of the total net carbon emissions in the Tacheng area.Hefeng County and Emin County accounted for 20.89% of the total net carbon emissions in the Tacheng area.Tuoli County was the carbon sink in the Tacheng area;(3) For the carbon emission effects,most areas in the Tacheng area showed ecological abundance before 2000,but ecological deficit appeared after 2000.[Conclusion] Shawan County,Wusu City and Hefeng County showed an obvious ecological deficit,and these will be the key control areas for carbon emission reduction in the Tacheng area in the future.
