The Research Of The Interaction Between The Action Of Peasant Agent Based On BDI And The Marginalization Of Arable Land

LUCC is one of the important components of global environmental change, but also geography research focus. LUCC research based on macro scale is difficult to interpreting land use decision maker’s intentions and behavior. Using MAS model to simulate the land use behavior of the decision makers to explore the intrinsic relationship between the human and the natural environment is an important method.From the aspect of the relationship between the behavior of household and land use changes this article mainly use MAS model based on BDI constructing the frame of the mutual influences between the household’s land use behavior and the marginalization of the arable land. Xianning Hubei was chosen as an example; in Xianning we chose two villages where each from mountain and plain disclosing the land use behavior of the mechanism of household from time and space perspective.First the overall Xianning arable land marginalization degree background was introduced, then use the MAS based on BDI to calculate farmer household’s decision, the a clear understanding at first is showed based on the current situation of arable land arrangement, in the next years arable land behavior decision may be accordance with the last year. But farmer household will weigh on other farmer aspiration; produce price changes as well as the adjustment of policy to determine a final decision. Accordingly the arable land arrangement become the next period of the faith, and the choice of2005and2010data were validated. The main result contain:(1) Land marginalization timing analysis in Xianning city showed that Xianning city arable land marginalization occurs mainly before2005, in2005arable land marginal situation gradually improved, but from2005to2009period a slight farmland marginalization still occurred.(2) The MAS model based on BDI quantitatively analysis arable land use behavior by the other farmers and market influence from microcosmic aspect. The Synthesis of intrinsic and extrinsic factors to determine the degree of importance of farmers land use arrangement can intuitively representing the household land use behavior. Combining with the experience of farmer households’land use behavior construct the rules of land use changes, the mutual feedback system form a continuous human and natural environment may be better constructed.(3) The pure farmer household proportion in Xianning before2005is more and more, the behavior of farmer household is basically agricultural land use structure adjustment, also a more cropland sublet out or abandoned. By2005, the proportion of pure farmer household reduced gradually, arable land deterioration happens more, but also cultivate specialist phenomenon, which prevent from the overall occur of farmland marginalization occurs.The advantage of this model is that the use of the continuous function from0to1quantitatively to analysis arable land behavior decision-making of multiple factors, and continuously reflects the feedback relationship between land user and the farmer households’behavior.
