土地政策传导系统是由耕地保护、土地供应、固定资产投资、产业结构、人口等9个子系统组成的复杂系统，本项目运用新创立的关联数字矩阵反馈基模生成法，结合系统动力学的反馈分析理论、流率基本入树建模法、灵敏度分析方法、对策论、图论等方法，对该复杂系统土地经济协调发展进行反馈研究，提出政策传导的调控对策并给予反馈基模仿真评价预测，建立江西土地政策传导系统反馈仿真分析模型，进行调控对策的灵敏度分析和拟合度、预测能力评价，建立调控对策并呈交给江西土地调控职能部门。对于处在工业化和城市化进程中的中国来说，人地矛盾尤为尖锐，粮食安全与经济建设常难兼顾，土地利用的结构性矛盾突出，找出土地调控中的运行矛盾和解决对策，模拟土地政策传导走势，预测检验土地调控政策效应和结果，建立一套模拟宏观调控政策传导运行趋势的仿真预测模型和调控方案生成评价的新方法，进行推广应用，具有重要意义。

Land policy transmission system is a complex system composed of cultivated land protection, land supply, fixed assets investment, industrial structure, and population etc，totally nine subsystems. In this project, we use the newly founded the Feedback Archetype Generating Method based on the association of digital matrix, combining the system dynamics feedback analysis theory, rate variable fundamental in-tree modeling, sensitivity analysis method, game theory, graph theory and other methods. We carry on a feedback research on the complex system of land economic development, propose a policy regulation and give feedback archetypes simulation evaluation and prediction. Based on this research, we can build a feedback and simulation analysis model of Jiangxi land policy transmission system, and do study sensitivity analysis, fitting and prediction ability evaluation. Finally, we are able to establish the adjusting control countermeasures and submit them to Jiangxi land control functions. During a process of industrialization and civilization, there exists severe conflict between person and land, and between food safety and economic construction, and the land utilization structural contradiction is sharp. It is of important significance to find out the running contradictions and solutions in the current land regulation, simulate land policy trend, predict land policy effect and results, and finally establish a set of models to forecast and simulate the macroscopically adjusting control transmission operation trend of policies, and some new methods of control scheme generation and evaluation.
