摘要/Abstract

摘要： 在RS/GIS的支持下，采用地形图扫描矢量化法构建涨渡湖区域的数字高程模型（DEM），将DEM模型与涨渡湖区2003年的LANDSAT-7 TM遥感图像进行叠加分析，提取出不同湿地类型的平均高程。通过回归分析，建立起水位、淹没面积、容积的关系模型。结合试验区的农情状况和水利设施的排涝能力，对比分析出通江前后涨渡湖地区调蓄能力的变化：通江前湖区最大调蓄面积为38.75 km²，最大调蓄容量为1.644亿 m³；通江后其最大可淹没面积为273 km², 最大可调蓄容量为9亿 m³。

Abstract: The DEM model of Zhangdu Lake region is set up by means of topographic map scan supported by geographical information system. Using RS and GIS technology, DEM model was overlaid with the LANDSAT-7 TM image, average elevation of different wetland was drawn out. By carrying on statistical analysis to the data, the relation models of the water level and area, the water level and volume, and area and volume is computed. Combining with the agriculture condition and the ability of draining flood of water conservancy projects, the authors simulate in quantity the difference of storage capacity in Zhangdu Lake region before and after connecting to Yangtze River. In Zhangdu Lake region, the largest storage capacity is 1.644×10⁸m³ and the water area is 38.75 km² before connecting to Yangtze River, however, after connecting to Yangtze River, the largest storage capacity is 9×10⁸m³ and the water area is 2.73 ×10⁸m².

Key words: Zhangdu Lake region, digital elevation models, storage capacity, simulation analysis
