长江流域土地利用/覆盖变化驱动力及影响综述

Review of the Driving Forces and Impacts of Land Use/Cover Change in the Yangtze River Basin

  • 摘要: 长江流域是中国生态和社会经济的重要组成部分,土地利用/覆盖状态正经历着快速的变化。随着遥感技术、物联网、社交媒体的发展,可以获得海量的、多维度的土地利用/覆盖相关数据,围绕长江流域土地利用变化过程、驱动因素和生态响应的研究大量涌现,对长江流域的发展规划和生态保护提供了一定的决策依据。首先梳理了当前长江流域土地利用/覆盖变化相关研究,然后从土地利用/覆盖变化的驱动机制和生态效应两个方面阐述了研究方法和结论,最后从土地利用/覆盖产品差异、驱动因素区域性、生态环境变化过程的复杂性和生态服务价值评估的综合性方面讨论了现有研究面临的困难和挑战,以及未来研究可能的发展方向。

     

    Abstract: The Yangtze River Basin is an important part of China's ecology and social economy, and the land use/cover status is experiencing rapid changes. As the development of remote sensing technology, the Internet of things and social media, we can obtain huge, multi-dimensional relevant data of land use/cover, the process of land use/cover, driving factors and ecological response of research, the development of the Yangtze river basin planning and ecological protection provides a decision-making basis. First, this paper reviews the current research on land use/cover change in the Yangtze river basin, and then expounds the research methods and conclusions in terms of the driving mechanism and ecological effects of land use/cover change. Finally, this paper discusses the difficulties and challenges faced by existing researches from the differences of land use/cover products, regional driving factors, complexity of ecological environmental change process and comprehensive evaluation of ecological service value and the possible directions of future researches.
