| 摘要: |
| 应用GIS软件ARC/INFO,建立太湖流域海面一地面变化信息系统,并与数据采集系统、图像处理系统和计算机系统相结合,研究对本区人类社会经济发展、区域规划、工程建设和人民生活产生重大影响的气候、海面、地面变化和区域环境变迁．采用长江三角洲地区邻近海域21世纪前半期地区性RSL上升幅度预测方案进行研究,结果表明：随着海面的不断上升和太湖流域地面沉降的加剧,2000年到2050年,太湖流域处于高潮位以下区域逐渐扩大该研究成果可用计算机屏幕或图形终端显示,或用笔式绘图仪、静电绘图仪或打印机输出． |

| Abstract: |
| By using of ARC/INFO and varied information, pictures, data from (1) the map of Taihu lake basin's topography (1 :200000) by Nanjing Institute of Geography, Academia Sinica; (2) the map showing the velocities of the recent crustal vertical movement in the Yangtze River and its adjacent area by Hu Huiming, Huang Liren and Yang Guohua[3] ; and (3) the forecasting of absolute sea level changes in the front of 21st century by Zhu Jiwen and Xie Zhiren[4]', this report has build up the Geographical Information System about the sea level of the China' s Eastern sea coast region and ground changes of Taihu lake basin. The results forecast four different rise of sea levels (RSL) under aboslute sea level changes in the early 21st century, as well as the lowering of the high tide of Taihu lake basin correspondingly (i.e. 2000a, 2025a, 2050a). All of the forecasting results will not only be demonstrated by screen, but also be drawn and printed. The GIS supplies the fundamental data and analytical service about the sea level and ground changes of the Taihu lake basin. |
