Raise of the comprehensive grain production ability is an important way to make sure the food security in China.This paper selected Baoquanling reclamation area as the study area,which is located in Heilongjiang Province.The time is divided into two stages to analyze the change of the comprehensive grain production ability from 1999 to 2008 in this area.Fourteen typical impact factors were chosen from three aspects which are natural resources,agricultural production inputs and agricultural modernization level.An improved grey correlation method was used to analyze the impact factors which have affected the comprehensive grain production ability.Results showed that:the main impact factors working on the comprehensive grain production ability were different in different stages.In 1999—2002,agricultural films use,area of grain sowing,application of chemical fertilizer,multiple crop index were the most important factors,however,effective irrigation area,application of chemical fertilizer,total power of agricultural machinery,agricultural films use played a key role in raising the comprehensive grain production ability in 2003—2008.It is obvious that the impact strength of the agricultural modernization level is increasing.The paper proposed suggestions of strengthening scientific and technological support,implementing grain production policy.The study ressult provides theoretical basis for the departments responsible for food production decision-making to effectively improve the grain production in the agricultural reclamation area.
