Notes
This paper discribes the growth analysis of overmatured coastal black pine trees as a fundamental study for the construction of stand density control method. Growth characteristics of diameter at breast height and tree height were examined by the stem analysis of eight dead trees in Kyushu university forests in Sawara during the spring in 1990. 1. Growth curves of diameter or height rarely fitted Mitscherlich's formula as a basic one of saturated ones. 2. Even though some trees were much advanced in years, rich annual increments of diameter or height continued, or current increments increased after more than 100 year old. 3. Almost all of trees had 2 or 3 maximum points of current increment of diameter or height. From the results obtained, it is suggested that new growth models based on up-to-date idea are nessesary for the density control methods for coastal black pine stand.
海岸クロマツ林の維持・管理のあり方を検討する上での基礎資料とするために, 海岸クロマツ老齢木の樹幹解析による成長解析を行った. 1.直径及び樹高の成長曲線は飽和型となるものは少なく, 直線的あるいは指数関数的な形状を呈するものが多い. 2. 100年以上の高齢となっても, 直径及び樹高は良好な成長が持続する, あるいは成長量が増加するものがある. 3. 連年成長量最大の時期が1回ではなく, 2～3回出現するものが多い. 以上の結果より, 海岸クロマツ林の維持・管理のための密度管理法の開発には, 従来の考え方に基づく成長モデルの適用は困難であり, 新たな視点からの林分密度管理法の開発が必要であることが明らかとなった.
