| 摘 要： | 驱动力研究是土地利用变化研究中的核心问题。土地利用变化驱动力模型是分析土地利用变化原因和结果的有力工具，模型通过情景分析可为土地利用规划与决策提供依据。基于不同理论的驱动力研究方法很多，论文选取了几种国内外应用较多的LUCC驱动力模型进行综述，分析了每个模型的优缺点及适用范围，最后得出结论：1) 基于过程的动态模型更适于研究复杂的土地利用系统。2) 基于经验的统计模型能弥补基于过程的动态模型的不足。3) 基于不同学科背景的模型进一步集成将是LUCC驱动力模型未来的发展趋势。

| Abstract: | Land use change is one of the main research subjects of global environmental change and sustainable development. Driving force is the core subject of LUCC, including both biophysical and human factors at diffeient temporal and spatial scales. Land-use models are useful for disentangling the complex suite of socio-economic and biophysical forces that influence the rate and spatial pattern of land use change and for estimating the impacts of changes in land use. Furthermore, models can support the exploration of future land use changes under different scenario conditions. Scenario analysis with land use models can support land use planning and policy. Many land use models are available, developed from different disciplinary backgrounds. This paper reviews several current land use change models to identify priority issues for future land use change modelling research All these models were divided into three classes: empirical and statistical models (e.g., regression model), dynamic (process-based) models (e.g., cellular automata model and system dynami model) and integrated models (e.g., conversion of land use and its effects, or CLUE model). For each of these models, a review is given and the advantages and disadvantages are discussed. Some suggestions for improving each model have also been put forward. Finally, we get three general conclusions. First, dynamic, process -based simulation models appear to be better suited to predict changes in land-use system than empirical, statistical models. Second, empirical, statistical models can complement dynamic (process-based) simulation models. Third, in the future, an integrated approach to modeling-that is based on multidisciplinary and cross-sectoral combining elements of different modelling techniques- will probably best serve the objective of improving understanding of land-use change processes. If this requirement is satisfied models will better support the analysis of land use dynamics and land use policy formulation. |
