China's Tibet autonomous region has witnessed great change as its economy, environmental protection, agriculture, tourism, poverty relief, and social security system maintain strong momentum.

Environmental protection 

Lalu Wetland National Nature Reserve is the world's highest and China's largest inland natural wetland in Tibet's capital Lhasa.

In order to protect the Lhasa's "green lung", the central and the local governments have invested 193 million yuan in phase 1 and phase 2 projects, including river cleaning and recovering desertified land. Now, phase 3 has been launched.

Currently, the wetland has recorded 332 species of plants, 43 species of terrestrial wild animals, 152 species of aquatic wild animals, and 101 species of insects, and birds including tadorna ferrugineas, bar-headed goose, and lark also inhabit in the place in winter.

Planting trees on mountains in Tibet is hard because of its dry climate, poor soil, strong winds and big temperature difference between day and night.

However, the local people succeeded to plant trees on Nanshan mountain and Beishan mountain with an average elevation of between 3,650 meters and 4,050 meters, and the average gradient on 60 degrees.

The program of tree planting on mountains around Lhasa started in 2012, and the city has greened its Nanshan mountain and Beishan mountain totaling 4,573 mu now.
