Boasting rich natural resources, magnificent sceneries and a variety of rare wildlife, Qinghai-Tibet Plateau is a magnet for researchers, photographers and travelers from all around the world.

However, with worsening global warming, the Qinghai-Tibet Plateau, known as the "third pole" of the world, is witnessing its glaciers melt.

With its fragile ecological environment, the plateau is vital to the planet's natural system.

And the Sanjiangyuan area (literally sources of three rivers) in Qinghai province, located at the hinterland of the plateau, holds paramount significance in local ecological conservation efforts.

Over the past three years, Qinghai province has ramped up efforts toward building an ecological civilization, with the grassland coverage up 26 percent from last year, and the number of endangered species increasing year by year.

What measures the province has taken to protect the ecological environment? And what results it has achieved? Let's follow China Daily reporter Eric Nilsson to have a look.
