	三堆子水文站为金沙江下段干流雅砻江汇入后基本水文站。为国家收集基本水文资料，为防汛抗旱服务，为水资源监督管理服务的流量一类精度站、泥沙一类站，作为金沙江下段，乌东德、白鹤滩、溪洛渡、向家坝四个梯级大型水电站的入库泥沙控制站，其地理位置和历史作用非常重要。因此在三堆子开展悬移质输沙总量变化情况，悬移质输沙量年内变化情况，悬移质泥沙组成相关的水文测验。对卵石推移质输沙量变化和年内分配过程，卵石推移质级配变化幅度，沙质推移质输沙量和输沙量年内过程，沙质推移质级配分配变化进行分析。了解泥沙特性、来源、数量及其时空变化，以便兴利除害，对于电站水库淤积，河道治理等具有十分重要的意义。<br />
Sanduizi Hydrological Station is the basic hydrological station after the lower section of Jinsha River enters the Yalong River. As a national basic hydrological data collection, service for flood control and drought relief, in the service of the supervision and management of water resources flow type of precision, sediment type of stand, as the lower Jinsha River, the east Germany, Crane Beach, Xiluodu and Xiangjiaba four cascade storage and sediment control stations of large hydropower station, its geographical location and historical role is very important. Therefore, hydrological tests related to the variation of the total amount of suspended sediment transport, the annual variation of suspended sediment transport, and the composition of suspended sediment were carried out in Sanduizi. The variation and annual distribution process of gravel bed load, the variation range of gravel bed load gradation, and the variation of sand bed load gradation and distribution were analyzed. It is of great significance to understand the characteristics, source, quantity and temporal and spatial variation of sediment in order to promote the benefit and eliminate the harm, for siltation of hydropower station reservoir and river course management.
