Routines to compute plants mortality
the number of trees is updated considering the mortality of the plants. for each tree that dies, a fraction mi of the mean biomass three types of mortality are considered:
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| integer(kind=short), | intent(in) | :: | dt |
time step (s) |
||
| real(kind=float), | intent(in) | :: | age |
current tree age (year) |
||
| real(kind=float), | intent(in) | :: | agemax |
maximum age (year) |
||
| real(kind=float), | intent(in) | :: | ms |
Fraction of mean stem biomass pools per tree on each dying tree |
||
| real(kind=float), | intent(in) | :: | mf |
Fraction of mean follioge biomass pools per tree on each dying tree |
||
| real(kind=float), | intent(in) | :: | mr |
Fraction of mean roots biomass pools per tree on each dying tree |
||
| real(kind=float), | intent(in) | :: | wSx1000 |
maximum permissible single-tree stem biomass (t) |
||
| real(kind=float), | intent(in) | :: | dc |
crown diameter (m) |
||
| real(kind=float), | intent(inout) | :: | density |
number of plants per hectar |
||
| real(kind=float), | intent(inout) | :: | cc |
canopy cover |
||
| real(kind=float), | intent(inout) | :: | ws |
stem biomass (t/ha) |
||
| real(kind=float), | intent(inout) | :: | wr |
roots biomass (t/ha) |
||
| real(kind=float), | intent(inout) | :: | wf |
folliage biomass (t/ha) |
||
| real(kind=float), | intent(inout) | :: | wtot |
total biomass (t/ha) |
