Abstract: This paper uses system dynamics software vensim to simulate the relations between all systems of the quantity of cultivated land resources in Chongqing City. By establishing SD model, it analyzes how the change in the quantity of cultivated land resources influences other systems and how other sub-systems influence the change in the quantity of cultivated land resources. It sets the parameters in the model with the historical data during the years 2002 to 2010 in Chongqing. After a historical examination on them, this paper uses parameter levels in different projects for a simulation influencing analysis. That is, if the cultivated land is used in a large quantity, the reduction speed of the quantity of cultivated land will, instead, be accelerated; and if the per unit yield of grain is increased, the demand on cultivated land will present a linear reduction state.
