  • 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。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。同时,提出了今后应加强研究的方向:应着重从机理层面对砒砂岩区的地形地貌空间结构分异特征、植被生境和群落分异特征及侵蚀时空分异特征进行深入研究,特别是将三者作为一个耦合系统的因素进行研究,解决制约砒砂岩区水土流失综合治理理论水平提升与实践的瓶颈问题;研究不同地貌单元的土壤侵蚀年内时空分异性特征及其成因,揭示坡沟系统水蚀年内时空分异性特征与自然植被时空分异性特征的耦合机理;揭示砒砂岩区地貌-植被-水蚀空间耦合机理。本综述可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一定参考。

     

    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. In addition, the negative correlation between the spatial structure of the vegetation community and the energy dissipation impedance of erosion requires further studies. It is necessary to study the differentiation spatial structure characteristics of topography and geomorphology, the differentiation characteristics of vegetation and community, and the differentiation temporal and spatial characteristics of erosion mechanism in the Pisha sandstone area, especially through the study on the factors of the three as a coupling system. We should also study the spatial and temporal characteristics of soil erosion in different landform units, reveal the coupling mechanism between the spatial-temporal characteristics of water erosion in the slope-gully system and those of natural vegetation, and find the spatial coupling mechanism of the landform-vegetation-water erosion in the Pisha stone area. The study will directly affect the theoretical foundation of a comprehensive model for treating soil erosion in the area.
