| Abstract: |
A Larix plantaion forest has been investigated to examine its stand structure and dynamics. A study plot is located in compartment 306 of the Tomakomai Experimental Forest with area 0.25-ha was introduced in 1984, followed by repeated tree censuses (5-10ｙear interval)., 北海道大学苫小牧研究林306林班カラマツの人工林の林分構造および動態を調べるため、1984年に面積0.25haの調査区を設け、5-10年間隔で、本数、胸高直径または胸高周囲長を計測している。更新台帳番号304800号 1960(S35)年 新植 カラマツ 長期観察林60号 1984(S59）年 設定。Hiura, T., Fujito, E., Ishii, T., Naniwa, A., Sugata, S., Ishida, K., Murakami, M., Kato, E., Maeno, H., Fukushima, Y. & Sakai, T.
