本文采用相对极差、加权变异系数和Jenks自然断裂系统分类法等方法，分别对2001~2010年江苏全省，苏南、苏中和苏北三大区域之间，三大区域内部以及13个地级市煤炭消费空间差异的演变进行了研究。结果表明：江苏省煤炭消费的空间差异呈逐步上升的趋势，苏南、苏中和苏北的绝对差异也在拉大；苏北地区的内部差异最大，苏中其次，苏南最小；各地级市煤炭消费类型的划分与变化与全省的经济格局基本一致。
本文採用相對極差、加權變異繫數和Jenks自然斷裂繫統分類法等方法，分彆對2001~2010年江囌全省，囌南、囌中和囌北三大區域之間，三大區域內部以及13箇地級市煤炭消費空間差異的縯變進行瞭研究。結果錶明：江囌省煤炭消費的空間差異呈逐步上升的趨勢，囌南、囌中和囌北的絕對差異也在拉大；囌北地區的內部差異最大，囌中其次，囌南最小；各地級市煤炭消費類型的劃分與變化與全省的經濟格跼基本一緻。

This paper analyses the evolution of the spatial difference of coal consumption in Jiangsu Province from three aspects,which involves the whole province,three major regions and thirteen prefecture-level cities. And some mathematical methods have been applied in the spatial difference analysis, such as the relative extreme difference, weighted variation coefficient and Jenks natural classification, etc. Results indicate that there has been an increasingly growing regional difference of coal consumption in Jiangsu Province. The north of Jiangsu has the largest internal difference, which is followed by the middle part of Jiangsu,and the smalleast is the south of Jiangsu. Meanwhile,coal consumption types and their changes in every prefecture-level city is consistent with the economic pattern of Jiangsu Province.
