湖南省1996-1999年洪灾经济损失分析

Economic loss analysis of flood disaster in Henan Province during 1996-1999

采用横断面研究方法,调查了湖南省在1996-1999年遭受洪灾的10722户居民,对洪灾造成的总经济损失、构成及其影响因素进行了分析。结果发现洪灾所导致的经济损失与洪灾的程度、类型及居民的受灾时间和灾前的经济水平有关。洪灾程度越大、受灾时间越长和灾前经济水平越高的地区,其洪灾的总经济损失越重;地区方面,山洪暴发地区的总经济损失最低;溃垸地区的经济损失最大。因此,在抗洪救灾中,要重点预防溃垸,设法缩短被淹时间,对经济水平较高的地区要重点保护。

In order to analyze the total economic loss from flood disaster during 1996 to 1999 in Hunan Province and its composition and influence factors, 10,722 families suffering the disaster are investigated with cross-sectional study. We found that the economic loss caused by the flood is related to the degree , type and period of the flood, and the economic level of the family before flood. The more severe the flood is, or the longer the flood lasts, or the higher the economic level before flood is, the more economic loss will occur. Flash flood areas had the lowest economic loss; the collapsed flood area had the highest economic loss. Therefore, we should give emphasis on the preventing the dike collapse, shortening the flooding period, and pay more attention to protection of the developed area in anti-flood.
