  • Received Date: 2006-03-25
  • This paper expounded the growing characteristics of L a rix gm elin ii classified stem ( dom inant stem,average stem, overtopped stem) and analyzed the relation between the growing characteristics of classified stemand its stand factors and locality factors by setting p lots and making trunk analysis. The results of this study indicated that L. gm elin iiwould transform each other at the different age and its transformation rate was 38. 9%, where the average stem was 50%, and the dom inating stem and overtopped stem were all 33. 3%. The transformation rates of classified stem from dom inant stem to average stem and from average stem to overtopped stemwere highest, the opposition was low. However, the transformation rate from dom inant stem to overtopped stemand from overtopped stem to dom inant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gm elin ii was going up. The altitude that classified stem mainlyconcentrated was less than 1 000 m, slope was less than 25°, aspect was south slope, position was at m iddleand lower, soil dep th less than 17 cm. The rate of no interconversion was 66. 7% among overtopped stem. Itshould cut the overtopped stem as intermediate cutting.

Abstract: This paper expounded the growing characteristics of L a rix gm elin ii classified stem ( dom inant stem,average stem, overtopped stem) and analyzed the relation between the growing characteristics of classified stemand its stand factors and locality factors by setting p lots and making trunk analysis. The results of this study indicated that L. gm elin iiwould transform each other at the different age and its transformation rate was 38. 9%, where the average stem was 50%, and the dom inating stem and overtopped stem were all 33. 3%. The transformation rates of classified stem from dom inant stem to average stem and from average stem to overtopped stemwere highest, the opposition was low. However, the transformation rate from dom inant stem to overtopped stemand from overtopped stem to dom inant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gm elin ii was going up. The altitude that classified stem mainlyconcentrated was less than 1 000 m, slope was less than 25°, aspect was south slope, position was at m iddleand lower, soil dep th less than 17 cm. The rate of no interconversion was 66. 7% among overtopped stem. Itshould cut the overtopped stem as intermediate cutting.
