Abstract: Tung oil tree’s phenological properties and their relation with change of latitude and height are analysed.The low temperature both in tung oil tree’s blossom period and winter is the limiting factor for tung oil tree’s development in higher mountains or more northern areas in subtropical zone. The relationship between tung oil tree’s yield,and meteorological factors and height can be transferred to the relationship between the yield and the phenological periods. The suitable cultivating height in various mountains of the subtropical zone of eastern China is calculated.Tung oil trees should be cultivated at the following districts:river valleys and basins below 500m in north subtropical zone;slopes and hills below 800m in mid-subtropical zone;mid-high mountainous areas over 800m in south-subtropical zone; while the wood oil trees at such districts as river valleys and basins below 500m in mid-and south-subtropical zone.
