In recent years, with the expansion of the city scale, Xizang Autonomous Region Environmental Protection Department has also strengthened the regular monitoring of the ecological environment, and successfully established monitoring stations in Lhasa, Shigatse, Qamdo and other cities to control air quality and noise pollution.

They provide accurate data for people to understand the air quality in Tibet.

At the same time, relevant departments at all levels in Tibet have also strengthened protection measures for grasslands, forests and wildlife, and made efforts to prevent desertification and soil erosion.

Due to the effective protection of natural forest resources and afforestation, the forest coverage rate in Tibet has increased from 1% in the 1950s to 6% now.

We have built many shelterbelts on the south bank of the Yarlung Zangbo River. Huang Yong, director of Shannan Forestry Bureau in Tibet, pointed out that after more than 20 years' efforts, we have finally built a shelter belt with a length of150km and an area of 300,000km2 (15km2 is one hectare). Thanks to these efforts, the Yarlung Zangbo River is much clearer now than before.

In the past, the road connecting Gongga Airport in Tibet and Shannan area was often flooded with sand, but now this road has become much cleaner.
