中文摘要	在回顾和评述绿洲的定义及其时空变化研究内容的基础上,就近年来绿洲时空变化过程中应用的方法(或指数)存在表述不清与混乱的现象,通过将绿洲作为单一地理景观类型来分析国内外文献中所涉及的各种研究方法和模型,并从绿洲作为干旱区特有资源的角度,按绿洲资源的变化分析、变化趋势与方向、空间分布特征等进行归纳和总结,讨论绿洲时空变化各种方法的概念、计算方法、意义及优缺点。
英文摘要	As a special geographic landscape unit,oasis was not only the research hotspots of modern geo-ecological processes and human activities in the arid area,but also was the basic places for sustainable human survival and development in the arid region. Under the background of global change,oasis change was one of the highlights of land degradation and regional sustainable development research topics. Based on the review of concept and contents of oasis change,Chinese scholars had done lots of researches on its spatiotemporal change and modelling in recently years. However,according to these present research papers,there were some misuse and confusions in these methods (or indices),such as abnormity. This paper took oasis as a specific resource and geographical landscape in the arid area. By detailed exploration of methods (or indices) embedded in research materials,three classifications of methods were identified as: the change of oasis resources,the change trend and direction of oasis,the spatial pattern of oasis. Then all of methods were analyzed under the concepts,calculation methods,application fields and suggestions,shortages. At last,this paper discussed and gave a remarkable review on the models and methods of oasis spatiotemporal change research. The quantity research methods (or model) is not only beneficial to the improvement of the oasis spatial and temporal variation research methods,enhance the comparability of oasis research,but also provides reference for other spatial and temporal variation of single landscape type. In future,spatial and temporal variation theory and the mechanism of oasis research needs to be further developed in order to achieve both supplement each other.
