In a bid to improve water quality and preserve environment of the lake, the local governments have taken a series of pollution control measures including the development and restoration of the wetland. To date, more than 20 wetland parks surrounding the lake have been established, playing a positive role in improving the ecology. [Photo/Xinhua]
