Influence Mechanism Of Large-scaled Grain Producers On Meteorological Disaster Adaptation Behavior In Poyang Lake Basin

[Significance] Meteorological disasters brought about by extreme weather events have had extensive and profound impacts on rice planting and production activities and the livelihoods of Large-scaled Grain Producers.Estimated losses,how Large-scaled Grain Producers adapt to meteorological disasters to maintain their livelihoods are the key to agricultural development and farmers’ survival.It is of great practical significance to explore the behavioral logic and impact mechanism of Large-scaled Grain Producers adapting to meteorological disasters,and to promote Large-scaled Grain Producers to actively and effectively adapt to meteorological disasters.[Objective] From the perspective of the theoretical analysis framework of planned behavior,the risk evaluation variables affecting behavior intention in the model of human active adaptation to climate change(MPPACC)were introduced to expand the three dimensions that affect the behavior intention of Large-scaled Grain Producers to take measures to adapt to meteorological disasters.Upgrade to four dimensions,build a TPB extended theoretical analysis framework,and deeply explore the internal impact mechanism between factors affecting the adaptation behavior of meteorological disasters of Large-scaled Grain Producers.[Methods] Based on this,a questionnaire was designed and field research was conducted.More than 400 questionnaires were distributed in nearly 22 large grain-producing counties in Province of Jiangxi.After screening,360 valid questionnaires were finally collected.Data statistical analysis software SPSS.25.0 software and AMOS.25.0 software are used for descriptive statistical analysis and empirical quantitative analysis of data based on structural equation modeling method to verify theoretical models and research hypotheses.[Contents] This study takes the Large-scaled Grain Producers in the surrounding areas of the Poyang Lake Basin as the research object,analyzes and identifies the influencing factors of the adaptive behavior of meteorological disasters of Large-scaled Grain Producers based on the theoretical basis of literature research,and draws on TRA theory,TPB theory,DTPB theory and MPPACC theory.,based on which research hypotheses are proposed and an extended analysis framework of TPB is constructed.[Results] The research results show that the three dimensions of risk assessment,behavioral attitude,and subjective norms of Large-scaled Grain Producers have a significant positive impact on their behavioral intention to take meteorological disaster adaptation measures.Among them,according to the standardized path coefficient from large to small The order is subjective norm(E=0.299,P<0.001)> risk assessment(E=0.283,P<0.001)> behavioral attitude(E=0.176,P=0.016),the subjective norm standardization path coefficient of Large-scaled Grain Producers is the largest,and the risk The second in the evaluation,behavioral attitude is the smallest,indicating that subjective norms have the greatest effect on the behavioral intention of Large-scaled Grain Producers to take measures to adapt to meteorological disasters.Perceived behavioral control(E=0.076,P=358)had no significant effect on behavioral intention,but perceived behavioral control had a direct and significant positive impact on the adaptation behavior of Large-scaled Grain Producers.also has a significant positive effect.The standardized path coefficient of perceptual behavior control(0.512,P<0.001)> the standardized path coefficient of behavioral intention(0.345,P<0.001),indicating that compared with behavioral intention,perceived behavioral control has an impact on the adaptation behavior of Large-scaled Grain Producers.bigger.In addition,from the index variables of each dimension,it can be seen that the severity risk perception,the possibility risk perception,the perceived usefulness,the perceived ease of use,the compatibility,the influence of colleagues,the influence of superiors,self-efficacy,resource convenience conditions,and technical convenience conditions are The important factors for the Large-scaled Grain Producers to take measures to adapt to meteorological disasters have played a significant positive role.[Suggestions] Based on the research conclusions,suggestions and countermeasures are put forward for large grain growers and relevant government management departments:(1)Strengthen the publicity and education about the awareness of meteorological disasters;(2)Organize the training of meteorological disaster prevention and response skills;(3)Improve the construction of agricultural-related infrastructure and(4)Strengthen the public service capacity of meteorological disaster prevention;(5)Research and develop new varieties of rice that are resistant to disasters and actively promote them;(6)Take multiple measures to select a combination of adaptive measures.
