Meža biomasas un oglekļa novērtētājs
Novērtēt above-ground biomasa, ogleklis, and CO2e from DBH, koka augstums, koksnes blīvums, and sugu grupa in a darba plūsma tikai pārlūkprogrammā.
Sākt from iebūvētie atsauces vienādojumi, saglabāt your own coefficient sets, and fall back to DBH-only estimates when lauks data are incomplete.
Kā lietot
- Choose the novērtēt mode, sugu grupa, and a preset, then confirm whether the built-in values match your lokāls workflow.
- Enter DBH first, then add koka augstums and koksnes blīvums when the selected mode needs them.
- Turn on root biomasa if you want BGB, and switch the oglekļa īpatsvars between preset, suga-specific, or custom values as needed.
- Review the result, then kopēt it, koplietot the URL, or eksportēt JSON and CSV for later reuse.
Piemēri
Formulas
All inputs are normalized to cm, m, g/cm3, kg, and t before the selected equation runs.
- AGB = a × (rho × D^2 × H)^b
- AGB = a × rho^c × D^b
- AGB = a × D^b
- BGB = AGB × sakņu/dzinumu attiecība
- Ogleklis = total biomasa × oglekļa īpatsvars
- CO2e = ogleklis × 44 / 12
Vārdnīca
Diameter at breast augstums, measured at breast augstums or your lokāls standard.
Above-ground biomasa. This page reports it as the main biomasa result.
Below-ground biomasa. It is optional and uses a sakņu/dzinumu attiecība when enabled.
Basic koksnes blīvums or specific gravity used to tune the model.
The koplietot of biomasa assumed to be ogleklis. The default in this tool is 0.47.
A multiplier used to novērtēt BGB from AGB when root biomasa is turned on.
Ogleklis dioxide equivalent. Ogleklis is multiplied by 44/12 to convert to CO2e.
Biežāk uzdotie jautājumi
Vai varu to izmantot oficiālai oglekļa atskaitei?
No. This page is designed for lauka novērtējumi and quick planning, not for certified reporting or audit work.
Ko darīt, ja koka augstums nav pieejams?
Switch to the DBH + blīvums or tikai DBH priekšiestatījums. The page keeps the aprēķins moving when augstums is not available.
Vai varu ievadīt decimāldaļas ar komatu?
Yes. The page accepts both decimal commas and decimal punkti, along with simple unit suffixes.
Vai varu saglabāt savus koeficientus?
Yes. Saglabāt a pielāgots priekšiestatījums in this pārlūkprogramma, then eksportēt it as JSON if you want a portable kopēt.
Vai lapa sūta manus datus uz serveri?
No. Inputs, presets, and results stay in the pārlūkprogramma unless you explicitly kopēt or koplietot them.
Svarīgas piezīmes
- Built-in equations are reference values only. Replace them with approved lokāls coefficients when you have them.
- koksnes blīvums, oglekļa īpatsvars, and sakņu/dzinumu attiecība can vary by suga, objekts, and data source.
- Root biomasa is optional. Leave it off if you only need AGB.
- Per-hectare values depend on the parauglaukums platība you enter. The page does not infer stand platība for you.
- Avoid putting private stand names into koplietot URLs if they should not be public.
