基于Arc View和ArcInfo的不同重现期洪水淹没区域的预测以及成图方法——以西安市浐灞生态区为例

The Forecasting Method and Cartography of the Submersed Areas in Different Return Period Based on ArcView and ArcInfo——Taking Chanba Ecology Region as an Example

以西安市浐灞生态区为例,详细叙述了如何采集数据,并且基于Arc View和ArcInfo对数据进行处理和分析,最终计算不同重现期洪水淹没区域的范围和面积并成图,并对该区的淹没情况作了分析,为相关部门采取防范措施提供了依据,为浐灞生态区的建设提供了参考。

Taking Chanba Ecological Region as an example, the follows are narrated detailedly, how to collect data, how to manage and analyze data, and then compute the submersed range and areas in different return period and draw the map based on ArcView and ArcInfo. Then, the submersed complexion of this region is analyzed. It offered foundation for correlative departments＇ taking action and also provided references for the constructing of Chanba Ecological Region.
