==== Water resources====
The main characteristics of Guangzhou's water resources are that there are relatively few local water resources and relatively abundant transit water resources. The city's water area is 74,400 hectares, accounting for 10.05% of the city's land area. The main rivers include Beijiang, Dongjiang North Mainstream, Zengjiang, Liuxi River, Baini River, Pearl River Guangzhou Reach, Shiqiao Waterway, and Shawan Waterway. Beijiang, The Dongjiang River flows through Guangzhou City and merges with the Pearl River to flow into the sea. The local average total water resources is 7.979 billion cubic meters, including 7.881 billion cubic meters of surface water and 1.487 billion cubic meters of groundwater. Calculated based on the amount of local water resources and the permanent population counted in the sixth census in 2010, there are 1.0601 million cubic meters of water resources per square kilometer, with an average of 628 cubic meters per capita, which is one-half of the country's per capita water resources. The amount of water resources for transit passengers is 186.024 billion cubic meters, which is 23 times the total local water resources. The passenger water resources are mainly concentrated in the southern Wanghe District and Zengcheng District. The passenger water resources diverted from the Xijiang and Beijiang Rivers into Guangzhou City are 159.15 billion cubic meters, and the passenger water resources diverted from the Dongjiang River into the north mainstream of the Dongjiang River are 14.203 billion cubic meters. meters and the water inflow from the upper reaches of the Zengjiang River is 2.828 billion cubic meters. The southern river network area is in the tidal influence area, with large runoff and a strong tidal effect. The three major entrances of the Pearl River, Humen, Jiaomen, and Hongqili, enter the Lingding Ocean and exit the South China Sea in the south of Guangzhou City. The annual high tide volume is 271 billion cubic meters and the annual ebb tide volume is 408.8 billion cubic meters. The annual runoff of the three major entrances is 137.7 billion cubic meters. Compared with meters, the annual tide can bring a large amount of water, part of which is freshwater resources that can be utilized.<ref>The website of The People's Government of Guangzhou Municipality. https://www.gz.gov.cn/m_index.html {{Webarchive|url=https://web.archive.org/web/20240907222736/https://www.gz.gov.cn/m_index.html |date=September 7, 2024 }}</ref>
