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
