Morphological Characteristics
By the cold-resistant coniferous species, the type of vegetation, is a vertical natural zone, a vertical natural belt, a mountain cold temperature climate condition. The top forest community is similar to the "Chinese Vegetation" book in the southern mountain cold temperature coniferous forest.
Growth Environment
In general, the sea level of Yahausa coniferous forests in Schreads and fir be species is 2500m to 4500m (up to 4600m) ). The specific distribution of altitude varies depending on the geographical location of different advantages and their distribution.
Distribution range
Distributed in the subtropical region has a height of the mountain vertical band spectrum.
Giant Panda habitat
Ya Gaoshan acoustic is a suitable habitat of giant panda. The structure and dynamic laws have seriously affect the survival and prosperity of the giant panda and the maintenance of its evolution potential. It is the only scientific basis for restoring degraded giant panda habitat. Through the surface of the giant panda habitat, the 42nd forest windows of the giant panda habitats were investigated by the center of the forest, and the structure of the forest and its update and the big panda staple food were studied. The relationship between bamboo growth, forest window interference. Up to present the dynamics of the subharmonic needle forest. Provide scientific basis for the restoration of giant panda habitat. The results show that: 江 冷 a a f a f f a a a f 主 是 主 主 主 主 主 主 主 主 主 主 主 主 主 主 主 主 主 主 主The forest it consists is an important habitat in the giant panda. The age of the Minjiang florized population presents a continuous distribution pattern, and the age of the purple napper population is intermittently distributed. It has not been updated between 250 and 500A. Lin window interference and update phenomenon is common in this type of forest. 90% of the forest windows are distributed in the seedlings, young trees and big trees with the Minjiang fir and purple spruce. However, there are different trees with different trees in the forest window: the granted seedlings, young trees and big trees account for 82.5% of all updated trees. The updated seedlings of purple spruce and brown leaf birch are 11.3%. The renewal of the fir and purple spruce in Minjiang River is also affected by the growth of giant pandas in the forest: high food bamboo covers. Update the tree seedlings, the density of the young trees is low. That is, the growth of the main food bamboo inhibits the renewal of the fir and purple spruce in the streak.
