1991年是世界政治风云急剧变化的一年。以美国为首的多国部队在海湾地区开展的代号为“沙漠风暴”的大规模军事行动标志着当代战争已经进入高技术领域;苏联的解体和东欧的政权重新组合更加显示出一个新的多极化世界正在出现。这些政治领域的巨大变革影响着世界能源开发和资源市场,也影响着高新技术发展的方向和规模。1991年,也是大自然极不平静的一年,环太平洋带火山环上大规模火山喷发对世界自然环境带来巨大影响;中国华东地区的特大水灾造成了巨大经济损失。现代高技术的军事对抗、全球自然环境变迁的研究需要推动遥感技术向纵深方向迅速发展,这一年出版的遥感新著作也异彩纷呈。
1991 was a year of drastic changes in the world political situation. The large-scale military operation codenamed “Desert Storm” carried out by the U.S.-led multinational force in the Gulf marked that the contemporary war has entered the high-tech field; the disintegration of the Soviet Union and the reorganization of regimes in Eastern Europe have further shown a new multipolarization The world is emerging. The tremendous changes in these political fields have influenced the world’s energy development and resource markets as well as the direction and scale of hi-tech development. In 1991, it was a very unnatural year for nature. The massive volcanic eruption on the Pacific Rim with volcanoes exerted a great impact on the world’s natural environment. The huge floods in East China caused tremendous economic losses. The research of modern high-tech military confrontation and changes in the global natural environment needs to promote the rapid development of remote sensing technology in depth. The new remote sensing publications published this year are also colorful.
