摘要
分析了景观空间动态模型研究的现状及今后的重点发展方向 .论文重点介绍了随机景观模型、邻域规则模型和景观过程模型 (包括渗透模型、个体行为模型和空间生态系统模型 ) 3类景观空间模型的发展现状、存在的主要问题以及对这些模型途径进行完善的有关工作 ,并从确证性分析、有效性分析与敏感性分析等 3个方面阐述了模型检验技术的发展现状 .最后 ,总结了未来景观空间动态模型发展中应重点解决的主要问题 ,即模型算法的优化、尺度转换、模型的复杂化与简化、模型检验与评价 。
Along with the rapid development of remote sensing,geographic information system,computer and other supporting technologies,model approach has become the major method of landscape dynamic study.Based on literature review,this paper analyzed the current situation and some intending problems of the development of landscape spatial dynamic model.Three kinds of models,i.e.,stochastic landscape model,neighborhood rule model and landscape process model (including percolation model,individual-based landscape model and spatial ecosystem model) were mainly introduced,and their development status,existing problems and related improvement work were analyzed.The development of model test technologies,such as verification analysis,validation analysis,and sensitivity analysis,were also analyzed.Finally,this paper summed up six major problems that should be dealt with in the future development of the landscape spatial dynamic models.These problems included model arithmetic optimization,scale conversion,model complication and predigesting,model test and assessment,bringing forward of general model,and integration of the traditional model with social-economic factors.
