About
Pinus koraiensis is a species of pine known commonly as the Korean pine. It is a relic species of the Tertiary, identified as a rare tree species by United Nations. It is native to eastern Asia, in Korea, northeastern China, the temperate rainforests of the Russian Far East, and central Japan. In the north of its range, it grows at moderate elevations, typically 600 to 900 metres (2,000 to 3,000 feet), whereas further south, it is a mountain tree, growing at 2,000 to 2,600 m (6,600 to 8,500 ft) elevation in Japan. Other common names include "Chinese pinenut". The ancient woodland of P. koraiensis on the earth is about 50 million hectares, and China has about 30 million hectares, accounting for 60%. It is a second-class national key protected plant in China. P. koraiensis is a tree species with high economic and ecological value.
Uses
P. koraiensis is a precious tree species with both economic and ecological value. Ecologically, it has the functions of water and soil conservation – its root having a large water storage capacity, which is a "small reservoir" in the eyes of ecologists – and the function of maintaining biodiversity. Economically, every part of the plant can be used. In China, it has a long history of being used in food, beverage, health preservation and medical treatment. The ancients called its fruit "長壽果/longevity fruit". The traditional Chinese medicine "海松子/sea-pine nut" refers to the seeds of P. koraiensis, which is a nourishing and strengthening agent. At present, the high-tech industry of P. koraiensis has outstanding achievements in the fields of food, health products, medicine, cosmetics and fine chemicals.
