【摘要】 空间模型是土地利用/土地覆被变化研究的重要内容和方法,CLUE-S模型是这类模型中应用较多的一种。该文分析了CLUE-S模型的运行原理和结构组成,指出:CLUE-S模型运用系统论的方法处理不同土地利用类型间的竞争关系,在综合考虑诸多限制因素和转换规则的前提下,通过反复迭代运算,把土地利用变化类型逐步分配到一定的空间单元中,将模拟结果精确直观地反映到空间位置,是一个较好的土地利用变化空间模拟模型。在此基础上,系统阐述了模型5个组成模块的机理结构和6个参数文件的特征,并对参数内涵和设置规则进行了介绍。最后概述了CLUE-S模型在国内外的应用进展,分析了CLUE-S模型的应用前景和领域及模型的不足之处。更多还原

【Abstract】 LUCC(Land Use and Land Cover Change) is a major part and also a main cause of global environmental changes.The LUCC models are efficient tool and play important role to support the analysis of the processes and consequences of land use systems.The spatial models are important part and methods in land use/land cover change research.The CLUE-S model which is applied extensively belongs to the spatial models.The model allows multi-scale representation of the land use system and combines the evolution of land requirement at the regional level over a given period and specific location factors at the local level.In this paper,the operating principle and composition-structure of CLUE-S model are analyzed and it indicates that:CLUE-S model solves competitive relationship among the different land-use types with the method of system theory.On the premise of considering a number of constraints and transformation rules comprehensively,the model assigns types of land use change to spatial grids gradually by iterative calculations and makes simulating results display in the spatial location intuitively and accurately.Therefore the CLUE-S model is a good land-use change spatial simulation model.On this basis,mechanisms of the five modules are expatiated,which compose CLUE-S model and characteristics of the six parameterized files of the model.Moreover,a detailed account of rules and the connotation of parameters regarding the model is presented.Finally the progresses of CLUE-S model applying in domestic and international researches are outlined,and application prospect,application fields and shortcomings of the model are analyzed.更多还原
