Analyzing the Relationship between Periodic Height Increment and Height at the Beginning of the Increment Period in Even-Aged Pure Stands of Japanese Larch (Larix kaempferi) Based on Stem Analysis

摘要

The relationship between periodic height increment and height at the beginning of the increment period was analyzed in two even-aged (30 and 36 year-old) pure stands of Japanese larch (Larix kaempferi). To obtain the initial height data as accuratelyas possible, all living trees within the stands were felled, and then the heights for each tree for a series of ages were estimated by stem analysis. The result indicated that a significant weak correlation between periodic height increment and height atthe beginning of the period in the larch stands could occur for some increment periods. In conclusion, it is not necessarily the case that relationships do not exist between periodic height increment and height at the beginning of the increment period in even-aged pure stands.
