Panda—the National Treasure

As the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less. But at present, the number of pandas is increasing year by year. There are now so many pandas that some are being sent to other countries so that people there can enjoy them.
Nowadays, the biggest nature park for panda in China is in Sichuan. There is a research centre for nature and wild life there. Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.
复杂一点的：
In the wild, pandas usually are living a single life, the scope of activities of each individual is approximately 4-7 square kilometers around, its population scattered by the usually composed of individuals, each individuals are habitats in the same circumstances and conditions, share a source of food for the same region, and between the co-dependent constraints, naturally portfolio into a unified whole.
Pandas lack of facial expressions, the general through visual, olfactory and auditory to maintain communication links between population, the sense of smell is most important. In its anus sides have a bare region is the location of perianal gland, this gland secretion of a smell can bring sour material, it often in the base of tall tree trunks or other significant objects such as stones , the mound, with the perianal gland secretions smear, but also with feces and urine, as the mutual recognition between the markers, that their respective geographical location.
The pupil panda eyes like cats, with a longitudinal crack. The voice of the giant pandas more complicated, the experts can be used to differentiate various call for the sound spectrum analysis method, the light of its conduct and performance, thus expressed by the sounds of their instinct behavior, courtship and emotional state such as biology significance. The results show that the adult pandas calls from 12 clearer voice calls and Surge composed of the significance of its voice signals that can occupy areas, looking for a spouse, rearing cubs, by the fear of a threat, and so on, including the call to come low-come,bark, strong bark, yelling, screaming and other sounds, there are breath, the dark nose,and other voices.

By 9 months old, will be issued moan, drum nose, and a similar call such as cattle call, its significance has close adult. With its old growth and the increase in body weight, their call becomes increasingly complicated.
Panda nest hole width needles mixed forest, mostly in the hollow in the base of the tree or trees touting the Lair, tree holes is due to human harvesting at the side of the base of the tree cutting, after a few ax or for other reasons and decadent perforation , in the form of communication. Inside generally have 20-40 cm thick wood powder, flakes, rot block. Tree soliciting
Lair is surrounded by the roots form. These holes nest or den to the main tall fir tree, the environment in which are relatively quiet, nearby food rich in natural resources, hidden conditions are relatively good. Build a nest, structure relatively simple and rough. Inside the foreshadowing of discoid color usually, from out of Lairtitle from the dozens of root dry or fresh, with leaves of a tree branch, cold niitakayamensis, rattan and wood, moss, etc., and twigs or bamboo ends of the diameter of 0.5-2 cm in general, the length of 10-200 cm, a type of fir, Hung Cheng, wild cherry, azaleas, flowers attempted, cold niitakayamensis, kiwifruit arc, overlap after the frame as a nest, the smaller branches and moss overlap with the inner edge as a nest, the nest tree holes at the end of the use of wood powder and debris, pieces of wood and other building into shallow discoid. Lair around left many traces, such as the pad of the foot, hair, feces, lying on a point, as well as remnants of food, and so. Some compare the hole on the ground in front of steep, inconvenient access, it used the title to a diameter of 2 1 7 cm, length of 40-190 cm of fresh or dry fir, rhododendron, Hung Cheng, trees and flowers, such as the attempted tree branches, piled up dozens of centimeters high into the thick pad of the foot, and out of the caves are from the top of the foot pad through, the time is long, stamping on the very smooth.
