三峡库区河岸带经历了严重的侵蚀，可能会严重恶化库区生态系统。为了计算土壤侵蚀特征，在三峡库区进行了野外调查，在库区中部设置了12个侵蚀监测样带。结果表明，主要驱动力为水波、重力和地表径流。在夏季，当水库运行在较低的水位时，波浪侵蚀导致堤岸不稳定和堤岸坍塌。同时，由于多场大暴雨，地表径流侵蚀也很严重。在其他季节，当水库在冬季以相对较高的水位运行达到最高水位时，由于水面范围广和水路运输繁重，水波占上风。干流的土壤侵蚀最严重，出现的波浪频率和强度都较高。干流河岸带的波浪侵蚀速率在37 mm/年左右，最高可达53 mm/年，地表径流侵蚀最大可达15 mm/年。
The riparian zone of the Three Gorges Reservoir (TGR) has experienced substantial erosion that may severely deteriorate the reservoir ecosystem. To calculate soil erosion characteristics, field investigations have been conducted in the TGR area and 12 erosion-monitoring transects have been set in the middle TGR. The results showed that the dominating drive forces are water wave, gravity and surface runoff. In summer when the reservoir ran at lower water levels, wave erosion led to bank instability and bank collapses. Simultaneously, due to a number of heavy storms, surface runoff erosion was also severe. In other seasons when the reservoir ran at relative higher levels reaching the highest level in winter, water wave prevailed due to the wide range of water surface and heavy waterway transportation. Soil erosion was the most severe in the mainstream where higher frequency and intensity of waves occurred. The rates of wave erosion were around 37 mm/year with the highest being 53 mm/year, and surface runoff erosion was up to 15 mm/year in the main stream riparian zone.
