沉积物来源指纹识别通过使用诊断和保守指纹将采样的沉积物混合物和景观源材料联系起来，分配水侵蚀产生的沉积物来源。使用这种方法，可以阐明流域内活跃沉积物源的性质和位置，生成信息，这是设计和实施流域管理策略的关键先决条件。沉积物来源指纹识别科学在全球范围内持续吸引着大量研究，但迄今为止，中国的指纹识别研究相对较少。在这里，由于中国景观的独特性，指纹识别方法仍然面临重大挑战，包括高度分散或马赛克斑块的复杂土地利用配置以及高度动态的土地利用转化率，因此需要测试传统和新型示踪剂的歧视性力量和环境行为的物理基础。未来的研究需要调查示踪剂特性在不同地形环境中的适用性，并评估该方法在支持改进土壤和水可持续性管理方面的潜在战略效用。在这里，流域沉积物预算不同组成部分的独立观测数据的战略可用性以及地块、微流域和流域维护良好的研究基础设施为测试该方法和完善程序提供了直接的机会。这种跨尺度的详细测试对于促进沉积物源指纹识别作为科学和管理工具为中国的水土保持实践提供信息具有不可估量的价值。
Sediment source fingerprinting apportions the sources of sediment produced by water erosion by linking sampled sediment mixtures and landscape source materials using diagnostic and conservative fingerprints. Using this approach, the nature and location of active sediment sources across the catchment can be elucidated, generating information which is a key prerequisite for the design and implementation of catchment management strategies. The science of sediment source fingerprinting continues to attract much research globally, but to date, there have been relatively few fingerprinting studies in China. Here, there remain major challenges for the fingerprinting approach arising from the uniqueness of Chinese landscapes, including for instance, the complex land use configuration with highly fragmented or mosaic patches and the highly dynamic land use conversion rates, generating a need to test the physical basis for the discriminatory power and environmental behavior of both traditional and novel tracers. Future research is needed to investigate the applicability of tracer properties in different physiographic settings and to evaluate the potential strategic utility of the approach for supporting the improved management of soil and water sustainability. Here, the strategic availability of independent observation data for different components of catchment sediment budgets and well-maintained research infrastructure for plots, micro-catchments and drainage basins provides immediate opportunity for testing the approach and refining procedures. Such detailed testing across scales would be invaluable for promoting sediment source fingerprinting as both a scientific and management tool for informing soil and water conservation practices in China.
