China News Service, Bayannur, September 30 (Reporter Li Aiping) The Bayannur Municipal Government of Inner Mongolia Autonomous Region stated on the 30th that as the "kidney of nature" of the Yellow River's ecological security, Wuliangsuhai has implemented ecological water replenishment in the past five years. Maintained at 293 square kilometers, with an average water storage capacity of 420 million cubic meters, continuing to improve.
The Water Resources Department of the Inner Mongolia Autonomous Region believes that due to the continuous implementation of ecological water replenishment in Wuliangsuhai in recent years, it has broken the prediction that Wuliangsuhai will disappear in 10 to 20 years given by experts.
Wuliangsuhai is the largest functional wetland in the Yellow River Basin and the eighth largest freshwater lake in China. It undertakes important functions such as regulating the water volume of the Yellow River, protecting biodiversity, and improving regional climate. It is the "kidney of nature" of the Yellow River's ecological security.
However, due to the retreat of farmland and the entry of some urban domestic sewage and industrial wastewater into the Wuliangsu Sea, coupled with insufficient ecological replenishment, the water quality of Wuliangsu once deteriorated to inferior category five, and the area of the lake area was greatly reduced, which attracted the attention of Chinese officials.
In an interview with the media, Liu Zhiyong, deputy mayor of Bayannaoer City, said: “Through the treatment in recent years, we have deeply realized that the pollution problem of Wuliangsuhai Lake lies in the water and the cause lies on the shore. As a community of life, forests, lakes and grasses have transformed from simply'controlling lakes' to systematically'controlling watersheds', and coordinated the promotion of comprehensive management of all elements, all river basins, and all regions."
According to reports, in order to vigorously manage the Wuliangsu Sea, local officials have compiled a comprehensive management plan for the Wuliangsu Sea basin, as well as special management plans for mines, forestry, grasslands, and deserts to promote ecological management in key areas.
Strive for and implement a national pilot project for ecological protection and restoration of landscapes, forests, fields, lakes and grasses in the Wuliangsuhai Basin with a total investment of 5.678 billion yuan (RMB), and simultaneously implement point source, non-point source, and endogenous governance.
A reporter from Chinanews.com learned that through comprehensive measures and both the symptoms and the root causes, the overall quality of Wuliangsu seawater is generally stable in Category 5, and locally better than Category 5.
