Abstract: To provide a theoretical foundation for forecasting wood properties, rotation selection and efficient use of timber, wood properties of 17 year-old Machilus pauhoi plantation were examined using SilviScan^TM fast detection technology. The radical variation mode of anatomical traits, wood density, modulus of elasticity and their responses to climate change were analyzed. We also analyzed the relationship between growth ring width, growth ring age and wood property parameters. The results showed that the radical variation patterns of all the wood properties were different, with 7-11th growth ring being the turning point of the variation curves. Growth ring width had no significant correlation with wood density and cell wall to cavity ratio. Growth rate and growth ring age imposed significant impacts on most wood properties. Different climatic factors had different impacts on different wood properties. Relative humidity was the main factor affecting wood properties. The responses of microfibril angle and modulus of elasticity to climate change were more sensitive than other wood properties.
