摘要:

沙量平衡计算是一种探讨侵蚀泥沙从坡面、沟道等处侵蚀起到流域出口输出这一复杂过 程十分有效的研究方法, 该方法将流域内泥沙的侵蚀、输移、沉积和输出等过程进行综合考虑, 既 打破了流域泥沙研究的破碎性, 也可以有效地评价泥沙输移系统的有效性。近期国外泥沙平衡计 算研究在研究方法上有了很大的改进和提高, 对其进行总结和评价将有助于我国沙量平衡研究 的开展, 从而为流域水沙管理提供一个有效的方法和手段。

Abstract:

The sediment budget affords an effective conceptual framework for quantifying soil erosion, sediment mobilization, transportation, deposition and storage within, and sediment output from, a drainage basin. And it constructs a more complete picture of sediment generation and distribution within basins and permits an assessment of the efficiency of the sediment delivery system. A range of studies on it have been undertaken with more and more advanced methods such as GIS, RS, GPS, fallout radionuclide measurements, etc. around the world and have got some satisfying results, but sediment budget has been applied in few studies and has not been well developed in China, so the recent developments of methods in sediment budget researches were concluded and their advantages were evaluated to encourage the national development of sediment budget researches, and some problems in these researches were mentioned too, that will make sediment budget a helpful tool to establish a reliable and scientific basis for formulating catchment management strategies.

Key words: basin, sediment budget, small catchment, soil erosion
