In recent years, the ecological environment of the Lhalu Wetland in Lhasa, capital of the Xizang autonomous region, has been significantly improved thanks to a series of ecological civilization construction and protection efforts, said the Lhalu Wetland National Nature Reserve Management Bureau on Sunday.

The wetland has attracted hundreds of bird species, and the population and biological resources of plants and animals have been increasing in recent years, the bureau said.
