以县（市）域作为空间结构研究的点要素，对江苏省区域发展差异进行定量研究，分析了空间结构时空演变的区域发展原因。研究结果表明：江苏区域发展在20世纪80年代，以域面要素变化为主90年代，以空间点要素变化为主。最后，通过分析江苏区域发展差异的空间机制得出：当前各轴线的地位差异显著，以沿江轴线为主；各地空间结构发育程度存在差异，苏南以沪宁线为主要轴线，处于由轴线向网络化发展阶段，苏中处于由点向轴线发展的阶段，苏北处于增长极发展阶段。

以江苏省为实际背景。运用多目标线性规划法．对能源与社会经济、环境协调发晨的能源结构优化模型进行研究，从定量角度探讨江苏省可持续能源发展的对策方案。

Crude oil flow is a sort of oil spatial movement, and in China, it is large scale and covers wide area with extensive social-economic effects. This paper analyses the spatial structure of crude oil flow in China, the characters of its flow field and the layout of its flow track. The results show that oil flow in China has a spatial characteristic of centralized output and decentralized input; its spatial structure is composed of Source System in the shape of right-angled triangle, Confluence System in the shape of right-angled trapezium and Multiplex System in the shape of obtuse-angled triangle, which are mutually nested, and on a whole, the presence of Multiplex System balances and optimizes the flow layout; oil flow field in China can be divided into four parts, i.e. the North, North-west, East and South Field, two or three of which overlap with each other, extending the oil flow and making the flow more flexible and maneuverable; oil flow track is a multi-objective decision-making route and in the decision-making process oil transportation cost is one of the essential factors, in China, oil flow track falls into the Northeast, North, East, Northwest and South five cluster regions, which connect with each other, and series–parallel connection between various kinds of transportation channels is widely seen in them, reinforcing the supply security of crude oil.

从世界油气资源的空间结构入手，根据其与社会经济空间结构的耦合关系，提出世界油气工业三大空间结构模式，即协同发展（就近供应）模式、通道发展模式和点轴发展模式，以期能为我国油气工业的发展提供有益的思路和借鉴。

本研究以“1999年分省能源平衡表”及石油资源贸易与转运资料为基础，首先将全国26个石油流动省份划分为基本自给型、半自给型、净支出型和净补给型四种石油资源流动平衡类型及输流中心、汇流中心和交流中心三大流动职能类型，分析得出中国石油资源流动在地理空间上表现为集中输流和分散汇流的特征，其中源地系统的空间形态为直角三角形，汇地系统为直角梯形，源一汇复合系统则为钝角三角形。其次依据资源位势梯度力将中国石油流动划分为北部、西北、华东和华南四大流场。北部流场的石油流动轨迹在东北区呈现树状网络结构、在华北区为单枝二叉树结构，西北流场的流动轨迹形态为“X”形结构，华东流场为多中心“Ⅲ”字形结构，华南流场则为“Y”形结构。
