摘要

利用GIS软件对黑河金盆水库下游周至县的一些基础资料进行处理

利用内插法

生成洪水淹没区实体地形图。利用损失率计算模型对淹没区内损失状况进行了预评估。结果认为

金盆水库遭受10000a一遇的洪水重现期发生漫顶溃坝时

洪灾所造成的直接经济损失为50.355亿元

间接经济损失为9.0639亿元。通过对水库溃坝洪水淹没损失的计算分析

可以让防洪决策人员及水库管理人员对水库洪水可能产生的后果做到心中有数

平时认真做好科学合理的水量调度

防止灾害发生。

Abstract

Topographical map of flood areas in the lower reaches of Jinpen Reservoir was generated by using GIS software to process basic data of Zhouzhi County and using interpolation method. The model for the rate of loss was used to assess the loss status of the inundated area. When the reservoir metthe flood of a return period of 10 000 years

the overtopping dam-break incidentcould occur and the flood could cause the directe-conomic loss to -5. 035 5 109RMB and indirecteconomic loss to -9. 0639 108RMB. Calculation and analysis of the loss by dam-break flood in this paper will enable policy makers and reservoir supervisors to know the consequences of the floods and help them to dispatch water volume rationally to avoid the disaster.
