Sampling, Processing and Quality Control Methods
Step by Step Procedures
|
Step 1: |
Description:
|
Location / 位置
The tree census plot is located in compartment 116 of Nakagawa Experimental Forest. The area of the tree census is 1.5ha (50m x 50m x 6plot).
(ja)
調査地は中川研究林第116林班に位置する。調査区の面積は1.5ha(50m x 50m x 6plot)である。
|
|
Step 2: |
Description:
|
Targets to measure / 測定対象
The target trees were 18cm or more in girth at breast height (1.3 m). Individual trees were identified using numbered metal plates.
(ja)
金板を調査木に取り付け個体識別した。胸高周囲長18cm以上(全木)を調査対象とした。
|
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 the survey at the time of setting, diameter at breast height (DBH: 1.3 m above ground) was measured with a caliper (2 cm unit). Since 2005, girth at breast height (GBH: 1.3 m above ground) has been measured with steel tape.
(ja)
設定当時の調査では、測定対象木の胸高直径(地上1.3m)を、輪尺(りんじゃく)を用いて2cm括約で計測した。
2005年以降の調査から、胸高周囲長(地上1.3mで測定)をコンベックスを用いて計測した。
|
Instrument(s):
| caliper (Before2004), steel tape(After2005) / 輪尺(2004年以前),コンベックス(2005年以降) |
|
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.
