| 摘要: |
| 砒砂岩地区是黄河中游粗泥沙来源的核心区，是黄河流域生态保护的重点，揭示黄河中游砒砂岩地区地貌植被侵蚀耦合规律，对于砒砂岩区生态综合治理具有重要的理论指导价值。在国内相关领域的研究中，利用高清遥感航片及无人机采集的高精度资料，解译获取区域或小流域地形地貌空间结构特征或植被群落结构特征的研究已经取得了一些较为宝贵的研究成果，特别无人机遥感所获取的影像分辨率对于研究小流域地貌植被分布特征有较大的优势。本文评述了砒砂岩区侵蚀地貌特征、植被生境空间分异规律、侵蚀空间分异规律，以及砒砂岩区地貌-植被-侵蚀空间耦合关系研究进展，并展望了其研究发展趋势，提出了今后应加强研究的方向，可以为黄河流域砒砂岩区生态保护侵蚀规律研究及高质量发展提供有益参考。 |

| Abstract: |
| The soil-covered Pisha stone area is the core source area of coarse sediment in the Yellow River and has become the focal point of ecological control of the Yellow River Basin. It is thus vital to study the spatial distribution of erosion coupling between geomorphology, vegetation, and water in the soil-covered Pisha stone area. Some valuable research results have been obtained already by using high-definition remote sensing aerial photographs and-high precision data from unmanned aerial vehicles. In particular, the image resolution obtained by unmanned remote sensing reveals small watershed topographic features and the characteristics of vegetation structure. Thus, the use of remote sensing is vital for research involving the spatial distribution of soil erosion in the slopes of the Pisha stone area and the dynamics of the geomorphic spatial structure of the slopes. In addition, the negative correlation between the spatial structure of the vegetation community and the energy dissipation impedance of erosion requires further study. Research into soil erosion in the Pisha stone area thus represents an urgent scientific need whose outcome will directly affect the theoretical foundation of a comprehensive model for treating soil erosion in this area. |
