Land-use and land-cover (LULC) change is a dynamic and complex spatial process involving human-environment interactions with direct impact on the quality and distribution of our biophysical system. In the next decade, the United Nations Environment Program estimates more than 60% of the world's population will be concentrated in urban areas. Uncontrolled urbanization and development will increase pressures on natural habitats, forests, agricultural lands, and available water resources thus affecting climate change. There is a vital need to monitor the LULC change processes, understand the changes from environmental and social perspectives, and model the spatial dynamics of land change for forecasting patterns and assessing their ecological consequences. The goal of this research is to continue developing novel simulation modeling approaches that would improve scientific understanding and knowledge about the underlying interactions and mechanisms driving LULC change processes. The work is theoretically situated within the geographic information science and systems (GIS), computational intelligence, complexity and land use sciences disciplines. The specific objectives are to: (1) develop a new generation of computationally intelligent complex system models capable of incorporating human-environment interactions and change dynamics at several spatial scales; (2) test and compare the effectiveness of the developed models and advance them to address model reliability and usability for spatial decision-making; (3) extend the developed complex system models from common three dimensional representation to better depict the change process in a four dimensional land-air-water continuum. Collectively, this research program will incrementally develop more realistic LULC models capable of generating future outcome scenarios of land change dynamics. With the development of enhanced LULC models scientists and planners would be able to deepen their understanding of the complexity of land change processes and be better equipped to examine outcome scenarios towards effective planning, decision-making and policy assessment for environmental mitigation at local, national and global levels.

土地利用/土地覆被变化是一个动态的、复杂的空间过程，涉及到人类与环境的相互作用，直接影响到生物物理系统的质量和分布。联合国环境规划署估计，在未来十年，世界上超过60%的人口将集中在城市地区。不受控制的城市化和发展将增加对自然生境、森林、农业用地和现有水资源的压力，从而影响气候变化。迫切需要监测土地利用/土地利用变化过程，从环境和社会角度了解变化，建立土地变化的空间动态模型，以预测模式和评估其生态后果。本研究的目标是继续开发新的模拟建模方法，以提高对驱动LULC变化过程的潜在相互作用和机制的科学理解和知识。这项工作在理论上属于地理信息科学和系统（GIS），计算智能，复杂性和土地利用科学学科。具体目标是：（1）开发新一代计算智能复杂系统模型，能够在若干空间尺度上纳入人与环境的相互作用和变化动态;（2）测试和比较所开发模型的有效性，并改进这些模型，以解决空间决策的模型可靠性和可用性问题;（3）将复杂系统模式从常规的三维模式扩展到更好地描述四维陆-气-水连续体的变化过程。总的来说，这项研究计划将逐步开发更现实的LULC模型，能够产生未来的土地变化动态的结果情景。随着土地利用/土地利用变化强化模型的开发，科学家和规划者将能够加深对土地变化过程复杂性的理解，并能够更好地审查结果情景，以便在地方、国家和全球各级进行有效的环境缓解规划、决策和政策评估。
