Abstract: Relationship between diameter-at-foot (D0.0), diameter at breast high without bark(D), bark percentage (P), tree height (H) and DBH (D) of Fraxinus mandshurica and Juglans mandshurica in second growth in western slope of Changbai Mountains were studied. The standing volume models, diameter-at-foot standing volume models, and bark volume models were constructed. The ratios of D to D0.0, D to D of Fraxinus mandshurica and Juglans mandshurica were 0.7299 and 0.7658, 0.9789 and 0.9750, respectively. The bark-percentage models and high models of Fraxinus mandshurica and Juglans mandshurica were P=129.1956D-0.6129 and P=275.4582D-0.819, and H=36.007-693.244(D+19.687)-1 and H=29.255-318.636(D+8.972)-1, respectively. The one-variable volume models, two-variable volume models, and diameter-at-foot standing volume models of Fraxinus mandshurica and Juglans mandshurica were V=0.0002D2.31 and V=0.0004D2.1232, V=0.000048D2.01077H0.870343 and V=0.000042D1.772558H1.174785, and V=0.0001D0.02.4347 and V=0.0004D0.02.0698, respectively. The one-variable bark volume models and two-variable bark volume models of Fraxinus mandshurica and Juglans mandshurica were V=0.0002D1.8668 and V=0.0003D1.7812, and V=0.000019D1.452649H1.14834 and V=0.000062D1.556608H0.714036, respectively.
