Water supply and sanitation in China is undergoing a massive transition, while facing numerous challenges such as rapid urbanization, a widening gap between the rich and poor as well as urban and rural areas. Water scarcity and water pollution in China also pose great challenges. With the development of the society, people's demand for water has been constantly increasing, but the water resource available for human is sharply decreasing. The deterioration of ecosystem brought about by the water resource crisis threatens human's existence seriously. How to make use of the water resource more effectively and promote the sustainable development and protection of water resource has become an urgent problem that all the countries in the world face.
中國的供水與衛(wèi)生情況正在經(jīng)歷一次大規(guī)模轉(zhuǎn)型，同時也面臨著許多挑戰(zhàn)，諸如快速城市化、貧富差距和城鄉(xiāng)差距擴(kuò)大等。水資源短缺和水污染也給中國帶來極大的挑戰(zhàn)。隨著社會的發(fā)展，人類對水的需求不斷增加，但可以供人類使用的水資源卻急劇減少。水資源危機(jī)所帶來的生態(tài)系統(tǒng)惡化的問題嚴(yán)重威脅著人類的生存。如何更有效地利用水資源，推進(jìn)水資源的可持續(xù)開發(fā)和保護(hù)，已經(jīng)成為世界各國共同面對的緊迫問題。
