Wood Density and Moisture Content of Green Trees in Urban Area of Longyan, Fujian
The wood basic density, green density and moisture content of 30 species landscape trees planted in Longyan urban area had been determined. The results showed that the highest of basic density of softwood was Cupressus funebris(0.636 g·cm-3), the lowest wasAraucaria cunninghamii (0.462 g·cm-3). In hardwood, the highest of basic density wasAcacia confusa (0.757 g·cm-3), the lowest wasCeiba speciosa (0.228 g·cm-3). The highest of green density of softwood wasPodocarpus nagi(0.975 g·cm-3), the lowest wasAraucaria cunninghamii (0.838 g·cm-3). In hardwood, the highest of green density wasAcacia confusa(1.204g·cm-3), the lowest isAleurites moluccana (0.799 g·cm-3). The highest of moisture content of green wood in softwood wasP. nagi 105%, the lowest was Cupressus funebris (30%). In hardwood, the highest of moisture content of green wood wasCeiba speciosa (319%), the lowest wasCornus wilsonianaandCasuarina equisetifolia (both 56%). Between the south and north direction, the basic density, green density and moisture content of wood were not significantly different. Within the scope of 8 cm from the bark, the radial variation patterns of basic density and green density can be classified into five types: (1)Density increased from pith to bark; (2)Density decreased from pith to bark; (3)Density was not changed obviously from the bark of 8 cm scope; (4)Density was lower from the bark 3 to 5 cm; (5)Density was higher from the bark 3 to 5 cm. The radial variation patterns of the moisture content of green wood were the former four types as mentioned above.
