D─樟脑亚胺体系的不对称合成研究
基本信息
结项摘要
本课题以经济全球化和世界城市体系为背景，利用定性、定量、GIS等现代技术方法，研究开放条件下中国城市体系的空间结构。创新点有①从理论上提出了非均质条件下城市发展的主要经济联系方向论；②初步总结了近二十年来中国城市化进程和城市体系演变的状况和主要因素；③用与世界经济联系的指标对我国城市进入国际城市体系进行了展望；④用铁路客货流、人口迁移流、航空客流、进出口贸易流、信件流等实证资料深入研究了我国的对内对外联系，在此基础上划分的城市经济区，深刻揭示了开放条件下我国经济联系的空间格局，对全国城市体系规划提供了依据。已发表论文十七篇，在国内外已产生一定影响，还有一批成果即将发表，各项计划已经圆满完成。
