The vertical distribution in Jilin is 250m above sea level,1000-1200m in Hebei, Shandong and Shanxi,1500m in Henan and Shaanxi, and 3,300m in central and northwest Yunnan. There are natural forests in Xinglong, Hebei Province, Taihang Mountain in Shanxi Province, Weihe River basin north of Qinling Mountains in Shaanxi Province and Lancang River valley in Yunnan Province.

Extended data
Platycladus orientalis likes light, has a little shade tolerance when it is young, has strong adaptability and is not strict with soil requirements, and can grow in acidic, neutral, calcareous and light saline-alkali soils. Drought and barren resistance, strong germination ability, moderate cold tolerance, strong sunlight resistance, high temperature resistance and shallow roots, which are only distributed below 900m above sea level in Shandong, and grow well below 400m above sea level. Weak wind resistance.
Platycladus orientalis is cultivated and wild. Likes to be born in moist, fertile and well-drained calcareous soil, which is cold-resistant, drought-resistant and salt-tolerant, and can grow on flat land or cliffs; In the dry, poor-ridged mountains, the growth is slow and the plants are thin.
Shallow roots, but developed lateral roots, strong germination, pruning resistance, long life, smoke and dust resistance, sulfur dioxide, hydrogen chloride and other harmful gases, widely distributed, is one of the most widely used ornamental trees in China.
Platycladus orientalis can adapt to cold climate. However, in some years in this area (Yanshan County, Yunnan Province), the seedlings have been drained to a certain extent, with strong drought resistance, lax requirements for soil, strong saline-alkali resistance, and salt content of about 0.2% can also adapt to growth.
