卫星遥感面临应用的新挑战
陈述
遥感学报 , 1990,
Abstract: 遥感以对地观测为主体,属于空间技术应用领域的重要组成部分。20年来,我国遥感应用经历了引进消化的初级阶段,基本上形成了具有中国特色的、规模比较完整的技术体系。在国土资源、海洋环境调查、煤田与油气田勘探、黄金与多金属找矿、作物、草场长势监测与估产、冰雪水源与洪水灾情预报、大坝与电站选址论证、城市环境监测与规划管理等许多方面,取得了显著的成绩和社会经济效益。可以说,遥感应用已经由适应性实验阶段进入业务阶段。在经济建设部门建立了200多个专业性应用单位。拥有学位及高级

Decision Making and Knowledge Innovation in Advance
超前决策与知识创新——国家大地图集的经历和启示

陈述
地球信息科学 , 1999,
Abstract: 1950年中国科学院成立,我就从大学调进科学院来,一直在基层工作。先后参予了几个研究机构的筹建和开拓。酸甜苦辣,一言难尽。回顾建国初期承担“国家大地图集”的任务,深受启迪和教育。联系当前知识创新的思潮,谈谈对超前决策的认识和愿望。 1.国家任务,催人奋进 建国以前的30年间,中国大型地图集的代表作,主要是申报馆出版的“中华民国新地图”。50年代初,国际上认可的则是台湾出版的五卷“中国地图集”。国家地图集作为一个
地理信息系统的应用基础研究
陈述
地球信息科学 , 1997,
Abstract: 地理信息系统的应用基础研究和产业化的关系,也许可以用两句话概括:今天的产业化是昨天的应用基础研究的延伸,而今天的应用基础研究是为了明天的产业化。引进只能填补今天的空白;创新才会开拓未来的辉煌。 1 哥伦布会议 1996年6月,美国29个大学和研究机构的代表。作为UCGIS~②的成员。在俄亥俄州哥伦布市举行会议,共商未来十年地理信息系统的发展问题。经过认真推敲和提炼,提出“地理信息科学的优先研究领域”的报告。其中的观点很有借鉴和启发价值。
地球信息科学的推进与交流

Abstract: 岷江的上游古称汶川。2008年5月12日,汶川发生里氏8.0级地震,最大烈度达11度。震中位于汶川县映秀镇附近。灾情惨重:遇难人口超过69180人,失踪17400人,受灾人口达4561万,引起了全世界的关注,全国19个省市正组织对口支援灾区重建。
SOME INFORMATION OF QUATERNARY ENVIRONMENT CHANGES FROM SATELLITE IMAGE IN NORTH CHINA PLAIN
卫星遥感信息与华北平原第四纪环境变迁研究

陈述
第四纪研究 , 1990,
Abstract: The satellite image for micro demonstration and macro change monitoring can be used not only to detect the historical vestiges of environmental evolution and change, but to comprehensively study historical background and modern process of natural environment, and to analyze the effect of neotectonic movement, the process of modern force and the interference of human activities.The North China Plain is a compound mainly constructed by Quaternary sedimentary process and also some other multiple processes mixed up together such as flood and alluival fans and deltas, and marine deposits. Since the latest half century, the study on the North China Plain by Chinese geoscientists has experienced five stages, that is, concept detuction; relief surveying and geomorphological mapping; geological drilling and geophysical prospecting; aerial photogrammetry and monitoring on geo-dynamic phenomena; evolution modelling study and multiple dimension analysis.Since 1975, the mosaic imagery maps of the whole and also some local areas of the North China Plain have been published by Landsat MSS images geometrically corrected with different accuracies. The scales are ranged from 1:500 000 to 1:250 000. Multiple information has been provided for the study on Quaternary environment changes.1) Linements and Neotectonic MovementsThe linements and Neotectonic faults have increased 50 percent in Beijing area through ground checking. The Tan-Lu deep fault belt is extended thousand km. The fault belt with NNW strike is run through the North China Plain, Which plays a role in landform and river change control.2) The Seashore Change Since Holocene EpochAccording to the comprehensive analysis on geomorphological marks, archaeological and 14C dating, six old coast lines have been marked along the Bohai Sea and the Huanghai Sea.3) River Course Migration and River Bed Change155 old river course marks during various periods have been demarcated by using multidate comparison. Among these old river course marks, there are 26 abandoned by the Yellow River since 1855. On the flood and alluival fan of the Yongding River, the old river courses are divided into three stages. The migration of the old river courses and the neck points where the tributaries converged are controlled by neotectonic movement, and appearing regularities.4) Withering Away of Lakes and Changing of DepressionsThere are three groups of lakes and marshland in the North China Plain. Near the Baiyangdian Lake, 23 vestiges of marsh lakes have been discovered by tracing the remaining marks and analyzing the cultural developing marks. The withering process of the old lakes and swamps in the North China Plain has been analyzed.It has been proposed to establish a database for Quaternary environment of the North China Plain, which is used to store remotely sensed data, and ground observation and historical document records to reproduce, simulate and predict environment evolution process. Also it will be further used to be con
