Xiong'an, December 7 (China Youth Daily, China Youth Network reporter Zhu Hongyuan) "Whether the ecology is good or not, the birds know best;."Whether the water quality is good or not, the fish know first. This afternoon, at the press conference on the governance and protection of the ecological environment of Baiyangdian Lake held in Xiong'an New Area, Zhao Fengdong, member of the Party Working Committee and deputy director of the Management Committee of Xiong'an New Area, said that since the establishment of Xiong'an New Area, the biodiversity of Baiyangdian Lake has been significantly improved, with 269 species of wild birds, an increase of 63 species compared with before the establishment of the new area, and 46 species of wild fish, an increase of 19 species before the establishment of the new area. The water quality of Baiyangdian Lake has improved from the inferior level in 2017 and has remained stable for three consecutive years, which is the best level since 1988, when Baiyangdian Lake was restored to water storage.
Zhao Fengdong said that Xiong'an New Area comprehensively uses natural restoration and artificial restoration to coordinate the management of urban water, forest, field and lake systems, continuously optimize the ecological space of the lake area, strengthen the construction and management of bird habitats, increase the diversity of benthic organisms and fish, restore the integrity of the Baiyangdian ecosystem, and strive to improve the diversity, stability and sustainability of the ecosystem.
In addition, Xiong'an New Area has successively implemented 18 major ecological projects in four categories, including "ecological dredging, water system dredging, wetland restoration, and returning farmland to lake" in Baiyangdian. Scientifically formulate and implement the water replenishment plan of Baiyangdian Lake, coordinate the diversion of water from the Yellow River to Hebei and reclaimed water, and make every effort to open up the arterial network of hydrodynamic flow, so as to realize the "live" and "moving" of Baiyangdian water, and the water level of Baiyangdian Lake is stable at 65-7 meters.
It is understood that the four major types of projects have treated a total of 567 fish ponds, with a dredging area of about 25 square kilometers, more than 11.94 million cubic meters of polluted sediment, a total of about 27 kilometers of dredging channels, about 280 kilometers of embankments and enclosures, and about 16 square kilometers of expanding the water surface of Dianbo.
Over the past six years, the ecological environment management of Baiyangdian Lake has realized the transformation from the original fragmentation and point treatment to the current integrated system management of water replenishment, pollution control and flood control, and from the original single treatment of Baiyangdian Lake to the current system management of urban water, forest, field and lake. Through treatment, the source pollution in the lake area has been greatly eliminated, the hydrodynamic force has been continuously improved, the water environment has been significantly improved, and the ecological self-purification capacity has been continuously improved. Zhao Fengdong said.
