|Based on hydrological risk, the risk measurement indicators for various flood avoiding agriculturalterns are introduced in wetland restoration area in Lake Poyang. According to the values of these indicators,the benefit and risk of various flood avoiding agricultun patterns are analyzed.And then using benefit maximization and risk minimization as objective functions, a multiobjective planning model of integrated flood avoiding economic patterns is constructed.Several typical noninferior solutions to the model are generated by applying weighting method.The tradeoff' analysis of benefit and risk for different noninferior solutions, which indicates that planting vegetajectivehigh benef t and low risk pattern but surface aquaculture is a high benefit and risk pattern, may provide obfoundation for risk decision making of flood avoiding agriculture in the wetland restoration area.
