土壤频率磁化率因主要受风化成土作用强度影响，所以能够较好地指示土壤发育程度和相对成土年龄。
Frequency dependent susceptibility, however, dominantly influenced by the intensity of rock weathering and soil formation, can indicate soil development degrees and relative soil ages.
岩石风化成土作用是生态系统矿质元素的重要来源，也是全球矿质元素生物地球化学循环的重要环节。
Weathering and pedogenesis of rocks are important sources of mineral elements for ecological systems, and key processes of global biogeochemical cycling of mineral elements.
