    We investigated DBH growth of a 55-year-old hinoki plantation after ordinary thinning and line thinning in order to explore the thinning method to promote individual growth for overcrowding hinoki stands, and to examine the conditions that determine effectiveness of line thinning. The relative growth rate of DBH (RDBH) was compared among three periods; 3 years before thinning, 2 years immediately after thinning (Period I), and the following 5 years (Period II: from 3 to 7 years after thinning). The result confirmed the effectiveness of ordinary thinning for DBH growth even in overcrowded mature stand. On the other hand, RDBH decreased temporarily after line thinning during Period I compared to that before thinning. A Generalized Linear Modeling conducted for DBH as the objective variables, with the initial DBH, canopy length, and thinning method as explanatory variables, also suggested the ineffectiveness of line thinning in the investigated case. Further, multiple comparison of RDBH conducted for four groups of line-thinned residual trees with reference to their tree statuses (superior or inferior) and tree position (center or outer row) suggested that, in Period I, "thinning shock" such as water stress caused by a sudden environmental change might be one of the possible reasons contributing the growth suppression. In Period II, it is also suggested that the influence of thinning shock might disappeared or be weakened, and that the suppressed growth of the center-row, inferior trees were thought to have reduced the stand average of individual growth.

    Authorship:Principal investigator 

    本研究の目的は人工林における温暖化適応策の一つとして、気候変動下においても持続的に温暖化緩和サービスを受けることができるように植栽樹種を選択するための情報を提供することである。将来的に予測される温暖化状況下では、場所によっては現在に比べて人工林の成長が低下し、温暖化緩和サービスが低下する懸念が示唆されている。これを回避する策として、伐採後に再造林する際に温暖化した環境により適した樹種へと植え替えるという選択肢がある。本研究では温暖化に適応した人工林の植栽樹種選択を科学的に判断することを目的とする。
