Sampling, Processing and Quality Control Methods
|
Step by Step Procedures
|
| Step 1: |
|
Description:
|
Location / 位置
The tree census plot is located in compartment 317 of Uryu Experimental Forest. The area of the tree census is 0.50ha (100m x 50m).
(ja)
調査地は雨龍研究林第317林班に位置する。調査区の面積は0.50ha（100ｍ×50ｍ）である。
|
|
| Step 2: |
|
Description:
|
Targets to measure / 測定対象
The target trees were 4 cm or more in diameter at breast height (1.3 m). Individual trees were identified using numbered metal plates.
(ja)
胸高直径4cm以上を対象とした。金板を調査木に取り付け個体識別した。
|
|
Instrument(s):
| metal plate / アルミ製金板 |
|
| Step 3: |
|
Description:
|
Species / 樹種名
Species of the targeted trees were recorded.
(ja)
測定対象木の樹種を記録した。
|
|
| Step 4: |
|
Description:
|
Girth at breast height, Diameter at breast height / 胸高周囲長（きょうこう しゅういちょう）、胸高直径（きょうこうちょっけい）
In 1992 , diameter at breast height (DBH: 1.3 m above ground) was measured with a diameter tape measure (First decimal place).
(ja)
1992年の調査では測定対象木の胸高直径（地上1.3m）を、直径巻尺を用いて計測した（cm：小数点第一位）。
|
|
Instrument(s):
| diameter tape measure / 直径巻尺（1992年） |
|
| Step 5: |
|
Description:
|
Survival / 生枯（せいこ）
Survival or death of the individual was visually measured.
(ja)
測定対象木の生死を確認した。
|
|
| Step 6: |
|
Description:
|
Shortage of wood / 欠点（けってん）
Shortage of wood of the targeted trees was measured. Description of wood damage: broken, fallen, fungal-damaged, insect-damaged, frost crack, bent, bifurcated, unavailable (as timber).
(ja)
測定対象木を木材として利用した場合の欠点を記録した。記載内容：折れ、倒れ、菌害木（きんがいぼく）、虫害木（ちゅうがいぼく）、凍裂木（とうれつぼく）、曲がり、二叉（ふたまた）、採材不能（さいざいふのう。木材として使用不可能）。
|
|
| Step 7: |
|
Description:
|
Grade of wood quality 1 / 樹形級（じゅけいきゅう）
Grade of tree quality was classified into four categories (after the 'Soviet' classification) for trees in broadleaved forests or in mixed forests. Code indications. 1: overstory tree with good wood quality, 2: understory tree, which is expectable to grow a good overstory tree, 3a: a tree which interrupt a better tree, 3b: a tree with unstraight stem or with a sign of death, decay or weakening.
(ja)
「樹形級」は広葉樹林及び針広混交林に適用し、樹木を以下の4つに区分する（ソビエト式樹形級区分に準拠）。1級:優勢木、2級: 下層木（将来優勢木になる可能性を持つ優良木）、3a:あばれ木(1級・2級の樹木の生長を、直接阻害する樹木)、3b:幹形不良木・傾斜木.
|
|
| Step 8: |
|
Description:
|
Grade of wood quality 2 / 樹幹級（じゅかんきゅう）
Grade of tree quality was classified into five categories (after the 'Terasaki'classification) for trees in coniferous forests. Code indications. 1: overstory tree with good wood quality, 2: overstory tree with unstraight stem or with a sign of death, decay, or weakening, or that interrupt a better tree, 3: understory tree, which is expectable to continue vigorous growth, 4: suppressed understory tree, 5: understory tree with unstraight stem or with a sign of death, decay or weakening.
(ja)
「樹幹級」は針葉樹林に適用し、樹木を以下の5つに区分する（寺崎式樹形級区分に準拠）。1:上層の優良木、2:あばれ木、上層の樹冠過弱木・樹冠偏倚木・分岐木・被害木、3:下層木の良木(将来良好な生育が見込まれるもの)、4: 被圧木(ひあつぼく)、5:生育衰退木・倒木・枯損木・傾斜木.
