摘要
产业转移背景下区域能源消费、碳排放格局时空格局变化是近期研究者关注的热点。以处于产业转移期的泛长三角地区为例,以工业能源消费为对象,分析了1990,1995,2000,2005和2010年5个年份碳排放的空间格局和演变规律,探索了产业转移对碳排放格局演变的影响。结果表明,1990年以来工业碳排放稳步增长,高值区集中于长三角核心区;碳排放增长的区域差异较大,热点区域由长三角核心区向外围区转移;碳排放格局发生变化,排放重心呈现先东南向、后西北向移动的态势;工业重心和碳排放重心空间分离,但移动过程类似。研究认为,产业转移所引起的各地区工业产值、产品结构和碳排放强度的变化,与碳排放格局变化具有较大关联性,是影响区域碳排放格局变化的重要因素。
The spatial and temporal changes of energy consumption and carbon emissions under the background of industrial transfer beoame one of the research focus by researchers from various fields recently. Taking Pan-Yangtze River Delta area that at the stage of industrial transfer as the case area, the author analyzed the spatial pattern and its changes of carbon emissions caused by industry energy consumption with data at the years of 1990, 1995, 2000, 2005, and 2010. The absolute amount, percentage of carbon emissions and its gravity were used to indicate the changes of carbon emission patterns. The relationship between carbon emission patterns and regional industrial transfer was analyzed accordingly. Results indicated that the core areas of Yangtze River Delta were of higher carbon emissions than the peripheral areas since the year of 5990. However, the spatial pattern of carbon e missions also changed since 1990, and the hotspots moved from the core areas of Yangtze River Delta to the peripheral areas gradually. The proportion of carbon emissions of cores areas declined at the year of 2005. The carbon e missions gravity moved to the southeast before 2000 at the speeds of about 20kin per tive tears, and turned to the northwest after 2005 at the speed of 21 km per five years. Its locations of the years of 2000 and 2005 were almost the same. The industry gravity a,d carbon emission gravity were spatially separated but of similar moving path at different stages since 1990. emission gravity by causing the differentiation of regional industry out put. The economic devel.pment ot core areas of angtze River Delta was significantly faster than that of peripheral areas of Pan-Yangtze River Delta, and the industry gravity and carbon emission gravity moved to the southeast accordingly. With the implcmentation and promotion of industry transfer to the peripheral areas, such as Anhui province, Jiangxi province,est part of Zhejiang provirce, and north & midde parts of Jiangsu province, the economic development of periphelal areas were atcelerated and over-passed the core areas gradually. The industry gravity and carbon emission gravity turtted to the northwest accordingly. Moreover, the carbon emission intensity was one of the main factors causing the spatial separatism of industry gravity and carbon emission gravity. Although the decreasing 3f carbon emission intensity o( peripheral areas was faster, the core areas were of lower intensity since 5990. It was ;oncluded that the results provided reference and basis for regulating industrial transfer pattern to promoting energyaving activities and optimizing the construction the energy transport channel and production facilitie treeds of fast developing areas.
