摘要
20世纪80年代末开始,珠江三角洲河道因大规模无序采砂等原因,河床不同程度下切,引起各主要控制节点的水量分配比明显增减。对珠江三角洲马口、三水、思贤滘、天河、南华断面及八大出海口门20世纪80年代以来水量分配比的变化情况进行分析,为珠江三角洲的防汛抗旱和水资源开发利用提供参考依据。
Since the end of 1980s, the large - scaled disorderly sand excavation in the waterways in the Pearl River Delta caused the various levels of undercutting in the river beds and triggered the dramatic changes of the water distribution ratio of the major control nodes. The analysis has been carried out on the ratio variation in the sections including Makou, Sanshui, Sixianjiao, Tianhe and Nanhua, and eisht see - going outlets since 1980s. The analysis can be a reference to the flood control, drought combating in Pearl River Delta and water resources development.
