干旱区土地利用是土地管理研究的重要内容之一。由于土地利用不同部门之间利益冲突以及定量评估政策效果的困难，造成土地管理具有客观和主观上的复杂性。干旱地区由于受到水资源约束，探求其土地利用与经济发展、环境保护相适应的机制尤为迫切。本研究拟以中国内蒙古额济纳旗为例，以干旱区土地利用“自适应机制—实证模拟—政策调控”为主线，根据复杂适应系统理论、“太极轮”理论和“钟摆”理论，探讨土地利用中政府、经济、环境、农户等主体之间耦合和冲突的自适应机制。结合时空地理数据在Repast平台上进行土地复杂系统适应性仿真模拟和实证检验。通过对研究区1962年—2012年50年时间尺度的土地利用相关政策综合梳理和定量化，开展多情景模拟实验，从经济和环境相适应的角度比较不同政策调控对土地利用的效果。旨在为优化土地利用转型下的政策制定，实现干旱区土地利用和环境经济发展相适应提供科学依据和初步思路。

Land resources use in an arid environment is one of the most important direction under land management research. In the process of land use, the conflict of interest between different departments and the difficulty in quantitative evaluation of policy effects, objective and subjective complexity of land resource have cause the attention of human community to manage land resource through appropriate policies and regulations. Due to shortage of water resources in arid area, therefore, how to get a deeper understanding of adaptive mechanisms between economic development and environmental protection, is need to be solved as an urgent scientific issue. In this study, Ejina in northern Inner Mongolia are considered to be excellent archives that monitor land use changes. The structure of "adaptive mechanism-empirical simulation-policy regulation" has been put forward in this study. We are proposing the complex adaptive system, as well as Taiji-Tire framework and pendulum swing theory to explore the adaptive feedback mechanism of coupling and conflict between government, economy, environment and farmers. Empirical simulation is conducted with Java in Recursive Porous Agent Simulation Toolkit (Repast) based on spatiotemporal geography data. Through the comprehensive prescription and quantification of land use-related policies in the study area from 1962 to 2012, we conduct simulation scenarios to compare the effect of policy regulation in the process of land use via socio-economic and environmental sustainable development. This study aims to provide preliminary ideas for optimizing the policy formulation under the land transformation and achieve adaptive management in the process of matching environmental economic development in arid area.
