By investigation, studying and discussion for 9 years, the determination that it should be Pinus sibirica growing in the Mohe county, Daxing'anling Mountains area, China, rather thanpinus koraiensis there, is made to correct a false argument in some works from 1950s' till now that Pinus koraiensis area limit reach Daxing'anling Mountain. The results are as follows: (1) The species so called as Pinus koraiensis found in northwest of Daxing'anling Mountain is Pinus Sibirica indeed; There arc no natural distribution of Pinus Koraiensis in Daxing'anling Mountain. Its northwest area limit only reach Shcngshan, Aihui county; (3) There is about 500km of space between the area limits of Pinus koraiensis and that of Pinus sibirica, no mixed growing area. According to above, a sketch map is made to describe different area limit of the two species at Daxing'anling Mountain and nearby.
