摘要:
多年来，黄土高原地区持续开展了大规模的退耕还林还草生态工程建设，土地利用/覆被变化显著。因此，对其开展相关研究，探索其土地利用/覆被时空变化规律，有助于认知区域生态环境变化过程，为生态环境修复等研究提供支撑。本文通过综述国际黄土高原地区土地利用/覆被变化研究成果，阐述了黄土高原地区土地利用/覆被变化研究在分类体系、分类技术、格局–过程变化分析和驱动机制研究等方面所取得的最新进展，并对如何完善土地利用覆被变化分类体系、开展格局与过程耦合研究、构建综合驱动分析模型等问题进行了讨论。研究认为，构建特色分类体系、综合地理观测与遥感技术、研发综合分析模型将是未来黄土高原地区土地利用/覆被变化研究的重点。
Land use and land cover in the Loess Plateau had a significantly change in the past years because of the large scale of returning farmland into forest or grass. Therefore, related researches are required to explore the spatial-temporal law of LUCC in the Loess Plateau, which can contribute more to the study of regional eco-environment change process and support the research of ecological restoration. This paper reviewed the international studies of LUCC in the Loess Plateau. The research progress of classification system, classification technology of remote sensing images, pattern-process change analysis and driving forces of LUCC were illustrated. Then corresponding discussions about these questions were performed. We think that the construction of unique clas-sification system, the fusion of geographic observation and remote sensing and the development of comprehensive model will be hot topics of LUCC in the Loess Plateau in the future.
