The red pine is a famous precious economic tree with thick trunks, and the two big people can't hold them hand in hand. The tree grows high into the cloud, straight and straight, and is a natural pillar. From pine roots, pine leaves, and turpentine, you can also use turpentine, pine needle oil, rosin and other wood processing materials; red pine material is soft and soft, the structure is fine, the texture is straight and straight, the shape is beautiful and not easy to deform, and the resistance to decay is strong. Therefore, it is the fine wood for the construction of buildings, bridges, sleepers and furniture. Even the branches, bark, and roots of Korean pine can be used to make pulp and fiberboard.
In the Qing Dynasty, Heilongjiang Zhi had a record of the primitive forests of the red pines in Xiaoxing'anling. "The towering giant trees, the lush greens, the branches are connected, and the sky is covered, stretching for more than three hundred miles."
It is also the role of the backbone in the famous buildings such as the Great Hall of the People in the modern times; the red pine grows slowly and the tree age is very long. The four hundred years of red pine is a strong year. Generally, the red pine can live for six or seven hundred years. Pine is a symbol of longevity; red pine is not afraid of severe cold, and the seasons are evergreen.
The pine forest is the top community of the Xiaoxing'anling ecosystem. The ecological value is extremely precious. She maintains the ecological balance of Xiaoxing'anling and maintains the ecological security of Northeast China with Xiaoxing'anling as an ecological barrier.
However, from the development of Xiaoxing'anling in 1948 to the present, after 56 years of harvesting, the natural red pine forest has been reduced from the original 1.2 million hectares to less than 50,000 hectares, and there are only about 3 million mature forests left. The red pine forest covers the sky and the spectacular scenery.
