在厘清空间视角下权力作用机制的基础上,构建地缘位势模型,刻画“9·11”事件后中美俄在伊朗的地缘位势演化特征,结合国别研究尝试解读中美俄与伊朗的地缘关系,主要得出以下结论：1）美国在伊朗的地缘位势在负向高位区间频繁波动,俄罗斯的位势在正向中位区间小幅波动,美国和俄罗斯的波动呈现“强－强”机制,中国的位势变化则与其较为剥离,呈“S”型曲线大幅增长。2）中美俄在伊朗的地缘位势是地理位置、地缘外交、地缘经济和地缘文化各要素共同作用的结果,其中地理位置是基底要素,地缘外交是决定要素,地缘经济是驱动要素,地缘文化是协作要素。3）中伊的地缘战略空间互补性重叠,中国综合国力的增强和双边经贸依赖的加深提升着地缘关系的强度和密度;美伊的地缘关系偶有缓和但总体较差,呈现出的波动性是国内政治生态和国际政治环境下的双重应答;俄伊地缘关系紧密缘于传统地理空间邻近和地缘战略考量,两国间存在着由经济利益、政治选择、安全保障等各种因素构成的稳定却复杂的地缘关系网络。  相似文献   

地缘政治经济背景下中老-中越边境地区橡胶林时空扩展特征研究     

肖池伟  李鹏  封志明 《地球信息科学学报》2022,24(8):1512-1524

国家间地缘政治经济关系正在驱动区域土地利用变化,边境地区首当其冲。20世纪90年代以来,全球橡胶市场的强劲需求以及中南半岛与域外国家40多个地缘经济合作机制的实施,引起了包括中国与老挝(以下称“中老”)-中国与越南(以下称“中越”)边境地区橡胶林扩展种植在内的显著土地利用变化。基于此,利用Landsat影像构建的橡胶林落叶-新叶萌生期内植被-水分指数(Renormalized Vegetation Index, RNVI)组合算法,获取中老-中越边境地区1990年代以来中老、中越地缘政治经济关键节点的橡胶林种植信息,进而揭示中老、中越地缘政治经济关系对其边境地区橡胶林扩展的影响及其国别差异。结果表明:(1)在“替代种植”与边境农林合作等地缘政治经济影响下,中老-中越边境地区橡胶林种植面积由1992年的995.5 km²增加至2018年的5537.7 km²,增长近4.6倍,且呈明显的沿边性和跨境性;(2)随着中老磨憨-磨丁口岸开通、中老北部九省合作机制构建等,1992—2018年,中老边境沿线30 km缓冲区内橡胶林种植面积从244.7 km...  相似文献   

Thirty years on: Planetary climate planning and the Intergovernmental Negotiating Committee     

《Global Environmental Change》2023

On the occasion of the thirtieth anniversary of the United Nations Framework Convention on Climate Change, this principal supra-national institution remains paramount to the project of planetary climate planning and governance. Reflections on this anniversary should serve to recall the contestations through which this foundational institution was formed, and the delegate dynamics that continue to be reproduced in its wake. The contentious debates and political dynamics that afflicted the Intergovernmental Negotiating Committee tasked with crafting the Framework Convention on Climate Change, as well as dissension in the periphery, remain as relevant today as they were three decades ago. Reprising these dynamics through detailed historical and archival analysis, this article excavates the negotiations of the 1992 Framework Convention on Climate Change by the Intergovernmental Negotiating Committee, which met in 5 sessions during 1991–1992. The aim is to identify key fault-lines and conflicts in the lead-up to the finalization of the 1992 Convention, in order to demonstrate whose epistemic and normative commitments came to be reflected in the final outcome and to show how the legacy of this process endures to date. I seek to render visible actors and proposals peripheralized in the formation of planetary climate governance to extrapolate normative boundaries and proffer heterodox lessons from the margins.  相似文献
