采用IPCC方法,对西北地区能源消费的碳排放进行时空差异分析,并对碳排放地域类型作了划分。结果表明:1990—2013年,西北地区碳排放总量由1.91×108t增长至12.03×108t,碳排放强度由18.40t/万元降为9.87t/万元,碳排放压力从很低等级(Ⅰa)升为中上等级(Ⅱb)。碳排放的空间集聚特征明显,碳排放总量呈现出以关天城市群、河西走廊城市群、银川平原城市群为主核和以天山北坡城市群为副核的主—副核模式,碳排放强度由西北向东南降低,碳排放压力以第二亚欧大陆桥轴线城市带、银川平原城市群以及陕北能源基地为较高区域。依据碳排放总量、强度和压力,划分出了高高高型(乌鲁木齐、昌吉、兰州、银川、石嘴山、吴忠、延安、榆林、渭南)、高高低型(阿克苏)、高低高型(西安、宝鸡和咸阳)、低高高型(哈密、西宁、海西、嘉峪关和金昌)、低高低型(吐鲁番、巴音郭楞、白银、平凉、临夏和固原)、低低高型(克拉玛依和铜川)、低低低型(伊犁、塔城、黄南、玉树等25个市州)等7类碳排放地域类型,并对不同类型区的碳减排策略作了初步探讨。
The IPCC method was used to analyze the spatio-temporal differences in the carbon emissions of energy consumption in the northwest region, and the carbon emission region types were divided. The results show that from 1990 to 2013, the total carbon emissions in the northwestern region increased from 1.91×108t to 12.03×108t, the carbon emission intensity decreased from 18.40t/million to 9.87t/million, and the carbon emission pressure was very low (Ia ) It is promoted to the upper middle class (IIb). The spatial agglomeration characteristics of carbon emissions are obvious. The total carbon emission shows the main-sub nuclear pattern of Guan Tian City Group, Hexi Corridor City Group, Yinchuan Plain City Group as the secondary core, and the northern slope of the Tianshan City as the subnucleus. The emission intensity decreases from northwest to southeast, and the carbon emission pressure is higher in the urban belt of the second Eurasian Continental Bridge axis, the Yinchuan Plain urban agglomeration, and the Northern Shaanxi energy base. Based on the total amount of carbon emissions, intensity and pressure, high and high types (Urumqi, Changji, Lanzhou, Yinchuan, Shizuishan, Wuzhong, Yan’an, Yulin, Weinan), high and low (Akesu), high and low (Xi’an, Baoji and Xianyang), low-high and high-grade (Hami, Xining, Haixi, Jiayuguan and Jinchang), low-high and low-grade (Turpan, Bayingolin, Baiyin, Pingliang, Linxia, and Guyuan), low and high (Karamayi and Tongchuan) Four types of carbon emission areas, such as low-low-low-type (25 cities and counties such as Yili, Tacheng, Huangnan, and Yushu), etc., and preliminary discussions were made on carbon mitigation strategies in different types of areas.
