我国改革开放以来,随着经济迅速发展,许多城镇的需水量也快速地增长,但工业的发展带来的江河湖泊水质的污染也愈来愈严重,已影响到一些地区人民的生活。各级政府在寻找理想水源时,都把眼光投向地理位置偏僻、较少工业和生活污染、供水量稳定的水库水。在人们看来,水库水清澈、甘甜,往往在取用水库水时片面宣扬其水质优良,而对湖泊江河水夸大其受污染程度。这主要是人们对水库认识不足所致。 Since the reform and opening up in our country, with the rapid economic development, the demand for water in many towns and cities has also risen rapidly. However, the pollution of rivers and lakes caused by industrial development has also become increasingly serious and has affected the lives of people in some areas. When looking for the ideal source of water, governments at all levels have turned their attention to the reservoir water with a remote location with less industrial and domestic pollution and a stable water supply. In the view of people, the reservoir water is clear and sweet, and its water quality is often prevalently proclaimed when using reservoir water, while its pollution to lake and river water is exaggerated. This is mainly due to lack of understanding of the reservoir.
