Detailed Description

NCI juvenile growth - Version 1.

This is a growth shell object which applies a variant on the NCI (neighborhood competition index) function designed for juvenile trees.

Growth per year is Growth = Max Growth * Size Effect * Crowding Effect. The amount of growth is in cm/year. For multi-year timesteps, the behavior will calculate total growth with a loop. Each loop iteration will increment DBH for one year. For each year, the Size Effect (SE) value is recalculated with the previous year's new DBH value. All values for each year of growth are summed to get the growth for the timestep.

Size Effect = a * d10 ^ b, where d10 is diameter at 10 cm height. Crowding Effect = exp(-C * NCI ^ D). NCI is calculated with d10, not DBH, even for adults; the d10 - DBH conversion equation will be used with the sapling parameters.

This can only be applied to seedlings and saplings. An error will be thrown otherwise.

The parameter file call string for this to be diameter-incrementing with auto-height updating is "NCIJuvenileGrowth"; for diameter-only incrementing, use "NCIJuvenileGrowth diam only". The namestring for this behavior is "ncijuvenilegrowthshell".

Constructor & Destructor Documentation

clNCIJuvenileGrowth::clNCIJuvenileGrowth ( clSimManager p_oSimManager)

Constructor.

Parameters
p_oSimManagerSim Manager object.
clNCIJuvenileGrowth::~clNCIJuvenileGrowth ( )

Destructor.

Member Function Documentation

void clNCIJuvenileGrowth::AssembleUniqueTypes ( )
protected

Assembles a unique list of types applied to this behavior and places it in mp_iWhatBehaviorTypes.

float clNCIJuvenileGrowth::CalcDiameterGrowthValue ( clTree p_oTree,
clTreePopulation p_oPop,
float  fHeightGrowth 
)
virtual

Returns the value in the tree's float data member that holds the value that was calculated by PreGrowthCalcs().

Parameters
p_oTreeTree to which to apply growth.
p_oPopTree population object.
fHeightGrowthAmount of height growth, in m (ignored).
Returns
Amount of diameter growth, in cm.

Reimplemented from clGrowthBase.

float clNCIJuvenileGrowth::CalculateNCI ( clTree p_oTree,
clTreePopulation p_oPop,
clAllometry p_oAllom,
clPlot p_oPlot 
)
protected

Calculates the NCI value for a tree.

NCIi = Σ λk((D10k/q)α/distanceβ)
Parameters
p_oTreeTree for which to calculate NCI.
p_oPopTree population object.
p_oAllomAllometry object.
p_oPlotPlot object.
Returns
NCI value.
void clNCIJuvenileGrowth::DoShellSetup ( xercesc::DOMDocument *  p_oDoc)
virtual

Does setup.

  1. AssembleUniqueTypes() is called to create a list of unique behavior types.
  2. ReadParameterFile() is called to read the parameter file's data.
  3. ValidateData() is called to validate the data.
  4. GetTreeMemberCodes() is called to get tree data return codes.
  5. SetFunctionPointers() is called to set up our function pointers.
Parameters
p_oDocDOM tree of parsed input tree.

Reimplemented from clGrowthBase.

void clNCIJuvenileGrowth::GetTreeMemberCodes ( )
protected

Gets the return codes for needed tree data members.

Exceptions
modelErrif a code comes back -1 for any species/type combo to which this behavior is applied.
void clNCIJuvenileGrowth::PreGrowthCalcs ( clTreePopulation p_oPop)
virtual

Calculates growth for all NCI trees.

The values are stashed in the "Growth" tree float data member for later application.

Steps:

  1. Get all trees for this behavior.
  2. For each tree, calculate NCIi by calling the function in the function pointer NCI. Stash the value in "Growth" for each tree.
  3. Go through all the NCI trees again. Calculate the amount of growth for each using the equations above. Use the function pointers to make sure that the proper function forms are used. Stash the end result in "Growth".

This must be called first of any growth stuff, since it uses other trees' DBHs to calculate NCI, and these must be before growth has been applied.

Growth per timestep is calculated by looping over the number of years per timestep and incrementing the DBH.

Parameters
p_oPopTree population object.

Reimplemented from clGrowthBase.

void clNCIJuvenileGrowth::ReadParameterFile ( xercesc::DOMDocument *  p_oDoc)
protected

Reads data from the parameter file.

Parameters
p_oDocDOM tree of parsed input tree.
Exceptions
modelErrif this behavior has been applied to any types except sapling and seedling.
void clNCIJuvenileGrowth::SetNameData ( char *  cNameString)
virtual

Captures the namestring passed to this behavior.

This is overridden from clBehaviorBase so we can capture the namestring passed. Since this class can create multiple kinds of behaviors that function differently, this will capture what kind of behavior this is supposed to be.

Parameters
cNameStringBehavior's namestring.

Reimplemented from clBehaviorBase.

void clNCIJuvenileGrowth::ValidateData ( )
protected

Makes sure all input data is valid.

The following must all be true:

  • Max radius of neighbor effects must be >= 0
  • Max growth for each species must be > 0
  • DBH divisor must be > 0
Exceptions
modelErrif any of the above conditions are not met.
