| 摘 要： | 通过对珠江区地表径流量的分析评价,研究其水资源的时空分布特点及变化规律。珠江的水资源特点是水量相对丰沛,但时空分布极不均匀。东西差异大,南北差异小,自东向西逐渐递减,沿海地区多于内地,山地多于平原。水资源的年际变化较大,且往往出现连续丰水或连续枯水年的情况。年内分配不均,汛期4~9月径流量一般占全年的60%~90%。

| Abstract: | Based on the analysis and evaluation of the runoff,the temporal and spatial distribution and changes of water resources in the Pearl River area were studied.Water resources of the Pearl River are relatively abundant,but the spatial and temporal distribution is very uneven.The water resources differences between the east and west are greater than north and south,and the water resources are gradually decreasing from southeast to northwest.The water resources in the coastal areas and mountains are more than in the mainland and plain.The annual variation of runoff is larger and during the rainy period of the year usually accounts for 60% ~ 90%. |
