Longbaotan Nature Reserve has steep and erect mountains standing on both sides and extends like parallel lines leaving a 10 kilometers long and 3 kilometers wide ravine area with the traces of lakes on its surface and piles of paddles, which is actually a swamp featuring the type of alpine meadow.

The climate above the altitude of 4000 chi (a unit of length, 3chi = 1meter) is very cold and even in May and July some of the rainfalls will freeze into snow.

Sometimes the weather is fine but suddenly it will rain hails and snows within a minute, and is difficult for people to adjust to. However, this unique and strange geography environment is the home for some rareTibetan birds and animals and also a producing area for some precious herbs. It is reputed as 'the home of the black-neck crane' by the birds experts and more than ten kinds of birds are living here such as bar-headed goose, brown-headed gull, Yan'ou(a kind of gull), Chima Duck (a kind of wild duck), goosander and tetraogallus. And it is set as the Nature Reserve of Black-neck Crane.
