Intensive land use evaluation of farmers,modeling and simulation is the foundation of the sustainable utilization of cultivated land,the influencing factors of cultivated land intensive use of farm households and model construction and application,and actively guide farmers scientific and rational and efficient use of land,improve land productivity.In view of the current shortage of micro scale intensive land use model simulation method,using MAS(Multi-Agent System)model framework,starting from the interaction between individual farmers and environmental point of view,the model of cultivated land intensive farmers using the new structure to simulate and forecast the level of cultivated land intensive use of farm households using the model built,is important for theory and practice the significance and formulation of policy adjustment in rural areas and farmers.Based on the survey data of 2013-2015 in Mizhi County of Shaanxi Province Based on farmer,firstly cultivated land intensive farmers use factor analysis,find out the influence factors of cultivated land intensive utilization of farmers.Then,based on the MAS model,the model of cultivated land intensive use is constructed,which is verified by the actual survey data and the model is modified to make the model precision meet the requirements.Finally,the intensive utilization of cultivated land in 2016 was predicted:(1)Affected by the market,different types of farmers,farmers of similar types of part of the village of Mizhi County farmers cultivated land intensive use,effect of weight were 0.49,0.16,0.35,cultivated land intensive use of farm households affected by the market's largest,followed by the same household,the least is the same kind of farmers.(2)The construction model of cultivated land intensive use of farm households based on MAS framework,and use the 2014,2015 farmers cultivated land intensive use data to verify the model,the simulation result is more fit in 2014,2015 of the actual level of cultivated land intensive use,the simulation accuracy can reach 87%.The 2015 forecast for 2016 based on the simulation results,the results:Zhang Bao Zhuang village,the level of intensive use of cultivated land is basically unchanged,still belongs to the general and intensive utilization;Gao Zhuang,he Jia Zhuang,Dou Jia Gou,Peach Town Level of cultivated land intensive use has increased,but is still in a state of general intensive use;2015-2016 cattle ditch Lu,Jia Gou,cliff village of cultivated land intensive use level remains unchanged.On the whole,the intensive utilization level of Mizhi County is on the rise,but the intensive use level is still relatively low,between the village survey level of cultivated land intensive use in intensive use and the intensive use of the general type,land use level is still relatively extensive.Government should actively guide farmers to standardize farming,rational allocation of production materials,improve the efficiency of the use of production materials,and promote the intensive use of arable land.
