摘　　要：本文记载了五针白皮松（ＰｉｎｕｓｓｑｕａｍａｔａＸ.W.Ｌｉ）的地理分布；推断它为一残遗种，并分析了它的地质历史、气候、土壤、生物等生态因子。在此基础上探讨了它的潜在分布区，认为长江中下游南部和南岭以北的山地，四川盆地以及云南中部和东北部山地可以自然生长；长江以南其它地区可栽植，但冬、夏必须加强抗寒、抗旱管理，而更北的地区恐难以自然生长。This paper records the distribution of Pinus squamata,which is a relic species basedon its distributional area. Its ecological factors, such as geological history, climate,soil, biological factors, etc,are analyzed.Based on its ecological factors,its potentialdistributional areas are in the south of the middle and lower reaches of Yangtze river,the basin of Sichuan and the central and northeast areas of Yunan. In other places tothe south Yangtze River，measures must be provided for Pinus squamata of to combatlow temperature in winter and drought in summer,and it must be cultured in green-house in the more northern areas.
