Erhai ecological restoration has shown results, and the water buttercup has reappeared in the lakeside zone

On July 3, the State Council Information Office held a Chinese and foreign journalists' meeting titled "Strivers on the New Journey." Professor Kong Hainan from the School of Environmental Science and Engineering at Shanghai Jiao Tong University shared his experience participating in the ecological protection and restoration of Erhai Lake. The report introduced that since the launch of the national major water pollution control project, Kong Hainan has led a research team to remain stationed in the Erhai Lake basin for the long term, promoting water quality and aquatic ecological restoration. After continuous治理, the water quality of Erhai Lake has improved from its original Class IV to Class II across the entire lake, and the native aquatic plant Hydrilla verticillata has reappeared in the lakeshore zone. Kong Hainan recalled that in 2017, after the team waited by Erhai Lake for many years, they finally discovered Hydrilla verticillata growing naturally in Yangxi near Gusheng Village. He rushed to the site to confirm it and was extremely excited at the time. After retiring, he spent another six years participating in Hydrilla verticillata cultivation and promoted an integrated "productionresearchsales" model, hoping to further benefit local farmers in Eryuan from the achievements of ecological restoration.
