中国绿洲城市土地利用/覆盖变化研究进展

绿洲城市是干旱区人类生产和生活的集聚中心，也是人地关系最为敏感的区域之一。了解绿洲城市土地利用/覆盖变化的研究进展对于改善区域人地关系、促进绿洲城市可持续发展具有重要意义。利用系统综述方法，对研究我国绿洲城市土地利用/覆盖变化的相关文献进行梳理，在综述已有研究进展的基础上，探讨了已有研究存在的不足并对未来研究方向进行展望。绿洲城市土地利用/覆盖变化研究的相关文献数量和被引频次均呈增长趋势。已有研究主要在局地尺度上分析了绿洲城市土地利用/覆盖变化的过程、驱动机制和生态环境效应，关于绿洲城市可持续性和基于区域尺度的相关研究较少。因此，未来应在多个尺度上开展工作，综合研究绿洲城市土地利用/覆盖变化的过程、影响和可持续性。

The research progress of urban land use/cover change in the oasis cities of China

Oasis cities are agglomeration centers of human activities and the most sensitive areas in human-earth relationships in arid regions. In recent years, some oases in China have experienced large-scale urban land use/cover change (LUCC) due to rapidly socio-economic development. Such changes have adverse impacts on the regional environments and sustainability. To improve the human-earth relationships and promote the sustainable development of oasis cities in China, it is important to review and understand the current progress of LUCC of oasis cities.Based on the systematic review method, this paper gathered and reviewed the related literatures on LUCC of oasis cities in China. From summarizing the existing studies, this paper highlighted the limitations of the existing investigations and put forward some feasible future research directions. This study first retrieved 275 literatures about LUCC of the Chinese oasis cities from the China Academic Journal Network Publishing Database of China National Knowledge Infrastructure and Web of Science Core Collection. Then, the general characteristics of these literatures were quantified using the systematic review method. Finally, the scales, methods, key contents and progress of the existing studies were summarized and generalized using the research framework of “process-impact-sustainability”.This review confirmed that existing studies have focused on the process, influence and sustainability of LUCC of oasis cities. The number and citation frequency of related literatures on the study of LUCC of oasis cities displayed an increasing trend. Among them, the number and the increase amplitude of related research literatures on LUCC process of oasis cities are the highest. These studies laid a good foundation for the in-depth understanding of LUCC of oasis cities. Nonetheless, existing studies have limitations in terms of multi-scale analysis, comprehensive impact evaluation of environmental and socio-economic effects, and the research methods of sustainability. Additional research efforts are needed to address these limitations in future studies, so that we have better scientific basis to support rational urban planning and sustainable development in oasis cities in China.
