Development Mechanism and Simulation Research of Agricultural Area——A Case Study on Chengcheng County of Shaanxi
以陕西澄城县为例，建立系统动力学模型，模拟分析三种发展方案，发现功能协调方案是实现农业区域可持续发展的最优选择。
According to one of China's three main functional areas by developing content,agricultural area is the regional of better conditions for agricultural production,in order to provide agricultural products as the main function,to maintain and improve agricultural production capacity.Based on the main territorial function positioning to ensure national food security,the development mechanism of agricultural area was analyzed,the system dynamics model was established,and the development trends of agricultural was multi-scenario analyzed and simulated by taking Chengcheng County of Shaanxi as an example.Three types of representative program including aggregate expansion,functional coordination and traditional development model were optimized and comparatively analyzed.By comparative analysis,the functional coordination program is the optimal choice for the development of agricultural area.To realize the sustainable development of agricultural area,the Chengcheng County should adjust the industrial structure of agriculture,promote the synergistic development of agriculture and other industries,and broaden farmers' income sources.
