龙门黄河沙量记录研究揭示,黄土高原黄土的侵蚀现象是我国脆弱的黄土环境中出现的一种天然环境地质过程。在年际时间尺度上,其侵蚀强度表现出明显的脉动特征,且与太阳黑子活动周期有密切关系。迄今黄土高原上的人为经济活动并未明显加速这一侵蚀过程或改变它的脉动特征,因而人为活动不是支配黄土高原黄土侵蚀的主导因素。 Longitudinal Yellow River sediment records reveal that the erosion of loess in the Loess Plateau is a natural environmental geological process that appears in the fragile loess environment in China. In the interannual time scale, the erosion intensity showed obvious pulsation characteristics, and it was closely related to the activity cycle of sunspots. Up to now, man-made economic activities on the Loess Plateau have not obviously accelerated the process of erosion or changed its pulsation characteristics. Therefore, anthropogenic activities are not the dominant factor that dominate the loess erosion on the Loess Plateau.
