家户、土地对洪涝灾害的经济响应研究──湖南省洞庭湖区案例分析

A study on economic response of family economy and land use to flood disaster ──A case study of Dongting Lake Area, Hunan Province

通过对湖南省洞庭湖区家户经济与洪涝灾害关系展开的野外调查，和从行政门部与保险公司 获得的有关社会经济统计资料、案例资料，进行了衣户经济行为与土地经济行为的分析。结果表 明，家户对洪涝灾害的抵御能力主要受其经济能力的制约，土地一方面受到来自增加家户收入的压 力，另一方面受到来自必须给水以一定空间的压力，所以在尽量满足给水以一定空间的基础上，努 力提高单位土地的产出率，从而提高家户的经济收入，对这一湖区的农民家庭经济与洪涝灾害问题 的解决具有重要意义。

Based on the field investigation of relationship between peasant family economy and flood disaster in Dongting Lake area, Hunan Province and the socioeconomic statistics from administrative departments and insurance companies, an analysis of family and land economy behavior shows that the fight of family against the flood is mainly constrained by its economic ability. On the one hand, land sustains the pressure from increasing family income, and on the other hand, it sustains the pressure from providing water with some space. Therefore, under the condition of providing water with space to full, increasing the economic output rate of per capita land, then increasing the family economic income is of significance to solving the problem of peasant family economy and flood disaster.
