摘要
为了解近年来陕西省碳足迹的状况，采用~2006年IPCC国家温室气体清单指南》和中国《省级温室气体编制指南》推荐的方法测算了陕西省及其各市的碳足迹。结论如下：1995～2009年，陕西省碳足迹从4129．38x10。t上升到22460．23X10。t，增加了443．91％。从空间上全省碳足迹可分为3类：陕南始终为负值；陕北和渭南市较高；关中除渭南市以外的地区较低。14a间全省人均碳足迹由1．18t增加到5．95t；各市人均碳足迹，陕北较高，关中较低，陕南为负值。全省碳足迹密度从2．00t／hm。增高到10．90tfhrn2。陕西省的人均和单位面积的碳足迹远高于应对全球气候变化的目标，但空间上差异很大。以2009年为例，全省人均碳足迹是应对全球气候变化目标的2．98倍，而陕北则超过10倍，高于美国；关中为1．29～4．57倍。全省2009年碳足迹密度是应对全球气候变化目标的4．89倍；渭南、咸阳、西安3市高达9．63～16．95倍；榆林、铜川I、延安和宝鸡4市为3．54～7．10倍；陕南植被的固碳作用消除了当地的碳排放外，还有剩余碳汇，但尚不能抵消陕北及关中的较高的碳足迹，因此总体看，对气候变化有负面影响，陕西的碳减排任务仍较重。
Global warming caused by carbon emissions would cause severe natural environment and social problems. Extensive work has been done in the area of carbon footprint and quite a few researches about Car- bon footprint has been reported home and abroad as well as some improvements. However, there are also some shortcomings such as mainly focusing on carbon emissions, whereas, less involving in carbon sequestra- tion. Shaanxi Province is an important province of western China, in recent years its economy has developed rapidly, but the carbon footprint of this province has not been reported. In this article, based on the method that recommended by ＂the 2006 IPCC Guidelines for National Greenhouse Gas Inventories＂ and Chinese＂ Guidelines for Provincial Greenhouse Gas Inventories＂, the study on spatio-temporal changes of carbon foot- print is performed in Shaanxi Province. Results of the study show that during the period from 1995 to 2011, Shaanxi＇s carbon footprint increased from 4 129.38 ~ 104t to 22 460.23 ~ 104t, or rose by 443.91%. The carbon footprints of 10 cities in Shaanxi Province can be divided into three types. It is always a carbon sink in south- ern Shaanxi, higher in northern Shaanxi and Weinan City, and yet lower in Guanzhong region excluding Wein- an City. The carbon footprint per capita grew from 1.18 t to 5.95 t in the past 14 years in Shaanxi Province. Concerning the carbon footprint per capita of cities in Shaanxi Province, it is higher in northern Shaanxi, low- er in Guanzhong regions, and negative in southern Shaanxi. For example, it ranges as Yulin City, Yan＇an City, Weinan City, Tongchuan City, Xianyang City, Baoji City, Xi＇an City, Hanzhong City, Ankang City and Shan- gluo City in descending order according to the carbon footprint per capita in 2009. As regards the carbon foot- print per unit area, it increased from 2.00 t/hm2 to 10.90 t/hm2 in the whole province. Besides, the carbon foot- print per capita and per unit area in Shaanxi Province is higher than the target which set fo
