讨论了目前应用比较广泛的几种测算岩石侵蚀速率的方法,将目前岩石侵蚀速率测算方法分为2类:一类为质量测算法,包括公式计算法、流域水化学监测法、样品称重法;另一类为几何测算法,包括微侵蚀测量仪法、对比计算法和宇宙成因核素法。探讨了各方法的测算原理、优缺点及其适用领域,质量测算法中的公式计算法和流域水化学监测法比较适用于大面积的国土监测工作;样品称重法和3类几何测算法适用于尺度较小的地学研究和文物保护、工程技术等应用领域。最后,总结了岩石侵蚀速率研究者和案例地的地理分布规律,并对岩石侵蚀速率测算研究进行了展望。
The current methods of rock erosion rate estimation are discussed. The methods for calculating the rock erosion rate are divided into two categories: one is the mass measurement method, which includes the formula calculation method, the basin water chemistry monitoring method, the sample weighing method ; The other is the geometric calculation method, including the micro-erosion meter method, contrast calculation method and cosmic nuclide method. The principle of calculation, the advantages and disadvantages of each method and their applicable fields are discussed. The formula calculation method in the mass method and the water chemistry monitoring method are suitable for large-scale land surveying work. The sample weighing method and the three kinds of geometric methods are suitable In the small scale of geology research and cultural relics protection, engineering and technology applications. Finally, the authors summarized the geo-distribution rules of the rock erosion rate and the case ground, and put forward the prospect of the calculation of the rock erosion rate.
