【Abstract】 The regression equation based on tree height,diameter of breast height,volume of wood and tree age was established and the influences of site types on tree height,diameter of breast height and volume of wood were analyzed quantitatively through the research on 5 different site types of artificial Robinia pseucdoacacia forest at Guanshan Forest Farm in Jinchuan County.At the same time,the protecting and managing methods on artificial Robinia pseucdoacacia forest were primarily studied.更多还原
