Transformation of Chenhu Wetland

2023-07-17   

Recently, the reporter conducted an interview along the Yangtze River, and when they arrived at the delta area where the Yangtze River and Han River intersect, they saw that there were dense lakes and a water network. The only internationally important wetland in Wuhan, Chenhu Wetland, is located here. Walking up the embankment of Chenhu Lake, I only feel the vast water and clear clouds. Through a telescope, it was discovered that the dense black spots on the floating leaves of the lake in the distance were actually a group of water birds nesting and breeding here. The forest was even more bustling and bustling with birds. "Sink Lake Wetland, which once caused ecological deterioration due to fish culture in the lake, has now become a" bird paradise "," said Feng Jiang, an engineer in Caidian District Sink Lake Wetland Nature Reserve. Following Feng Jiang on the road of patrol, the reporter learned about the "past and present lives" of Chenhu Wetland. Chenhu Wetland is mainly composed of Chenhu Lake, Zhangjia Lake, Wangjiashehu Lake and some surrounding embankments, with a total area of 11579.1 hectares. It is the largest typical freshwater lake swamp wetland in Jianghan Plain, and also an important station of East Asia Australia Bird migration channel. The ecological environment of Chenhu Wetland has a significant impact on the Tongshun River basin, a tributary of the Yangtze River, and even the Yangtze River. It is also a nesting and breeding ground for many migratory birds, "Feng Jiang said. The Chenhu Wetland nourishes a side of life. Chen Weibing, the secretary of the original village branch of Yuqiao Village, Xiaosi Township, Caidian District, Wuhan City, said that the villagers nearby had been living on water and fishing for generations. "In the 1980s, the clear lake water could even be directly drunk". In 2008, Feng Jiang, who had just graduated from university, came to work in Chenhu Wetland. The first thing that caught his eye was the fish pond with a grid and the dense seine. The increasing density of purse seine fishing has made the ecology of Chenhu Lake unbearable, "said Chen Weibing. At first, fish were scattered in the pond, which increased farmers' income. Later, numerous fish ponds were contracted out for large-scale aquaculture. In order to increase production, farmers put a lot of feces and feed into the water. In addition, flocks of fish eat Aquatic plant. The water Eutrophication is serious. Some areas of the sink lake have become "green water" that is "smelly and dirty". At worst, it is a long-term inferior to Class V water body. In addition to enclosing the lake for fish farming, the high terrain of the Chenhu Wetland has also been reclaimed into farmland. Migratory birds are the most fond of eating fish, shrimp, and pecking crops. The conflicts between villagers and birds are increasing, and behaviors such as hunting wild birds and collecting bird eggs are prevalent. The water is polluted, people drive it away, and the birds are unwilling to come. The sinking lake has become completely unrecognizable, "said Chen Weibing. For a period of time, the flock of geese flying in for the winter often had nowhere to rest and had to repeatedly hover in the sky. Remembering pain through hard work. In 2013, Chenhu Wetland was included in the list of internationally important wetlands. In 2014, the "Interim Measures for Ecological Compensation in Wuhan Wetland Nature Reserve" was officially implemented. According to the ecological compensation standards, the farmland and fish ponds in the experimental zone, buffer zone, and core area of Chenhu Wetland can receive compensation ranging from 25 to 50 yuan per acre to guide surrounding farmers to adjust their planting and breeding methods, "Feng Jiang said. After the implementation of ecological compensation, coupled with the unremitting promotion of wetland protection by the staff, the attitude of surrounding villagers has undergone a significant change. The crops were pecked by birds, and the villagers joked, 'Let's treat the birds to dinner.'. Since 2017, purse seine aquaculture has been completely prohibited in Chenhu Wetland, and all 32000 acres of purse seine in the protected area have been demolished
