Abstract:Chinese fir is an important timber tree in subtropical region of China.The site-index tables are produced in order to predict the productivity and to give reference in choosing proper site of plantation.Data of 1077 stem analysis of dominant trees from different planting areas were collected,18 guiding curves according to log A=a+b 1/A model have been developed individually according to different planting areas.Three height-growth patterns with different shape of curve are divided on the basis standard deviation of b value of 18 curves.Then,three series of site-index curves are developed from three height growth pattern,and are transformed into 3 site-index tables.These tables are reliable and available for classification and evaluation of forest site within respective range of application
