长江三角洲是我国经济快速发展的地区之一,但随着人口增长,工业化和城市化进程加快,资源紧缺和环境问题日趋严重。江苏、浙江和上海两省一市科技人员充分发挥RS、GIS、计算机制图技术及网络技术等学科前沿的优势,研制了“长江三角洲地区遥感卫星动态决策咨询系统”。在标准与规范的制定和指导下,建成了以乡为基本统计单元的区域地理数据库和专题数据库。对海量数据压缩和处理技术、多媒体技术、数据可比性、数据可靠性以及地理信息图谱等开展了研究。应用遥感技术对长江三角洲地区土地资源、长江岸线资源、上海市农用地资源、杭州湾海岸带滩涂资源,以及太湖水环境等进行调查与动态监测,为政府部门进行农田保护和城镇建设规划区“两区”划定、为1998年长江抗洪抢险、长江产业带规划和长江岸线资源利用规划、为上海市稳定菜田面积和粮食收购、进销、进口、储备及定价,以及杭州湾海岸带开发和滩涂围垦提供了科学依据和决策咨询服务。
The Yangtze River Delta is one of the regions with rapid economic development in our country. However, with population growth, industrialization and urbanization accelerating, the shortage of resources and environmental problems have become increasingly serious. The scientific and technological personnel in Jiangsu, Zhejiang and Shanghai, one city, gave full play to the leading edge of RS, GIS, computer graphics and network technologies, and developed the “Dynamic Decision Consulting System for Remote Sensing Satellites in the Yangtze River Delta.” With the formulation and guidance of standards and norms, a regional geography database and a thematic database with township as the basic statistical unit were built. Research has been conducted on massive data compression and processing technologies, multimedia technologies, data comparability, data reliability and geographic information maps. Remote sensing technology is applied to investigate and monitor the land resources, the resources of the Yangtze River, the resources of agricultural land in Shanghai, the resources of the coastal zone of Hangzhou Bay and the water environment of the Taihu Lake in the Yangtze River Delta. The “two districts” delineated as the plan for the flood control and rescue in the Yangtze River in the Yangtze River, the planning of the industrial belt in the Yangtze River and the utilization of the resources of the Yangtze River in 1998, and the plan for stabilizing the vegetable plot area and grain purchasing, import, sales, import, reserve and pricing in Shanghai, With development and beach reclamation provides a scientific basis and decision-making advisory services.
