Detailed Description

Stochastic Gap Growth, Version 1.0.

This behavior takes a shortcut for simulating rapid growth in high-light, very competitive conditions.

The behavior creates growth under gap conditions. To recognize gap conditions, it relies on the "Gap Light" grid produced by the clGapLight class. For any cell which has gap status, from the group of trees in that cell to which this behavior is applied, a tree is randomly chosen to be given whatever growth is necessary for it to reach the minimum DBH for adults. No other trees in the cell grow at all. In cells that have non-gap status, no trees at all grow.

To randomly select a tree to grow, this behavior uses a grid called "Growth Counter". The behavior counts up the number of eligible trees in each cell of "Growth Counter". It then multiplies a random number by the number of trees, arriving at a target tree (i.e. number 34 out of 56 found). Then this tree is given the amount of growth necessary for it to reach the minimum adult DBH.

The namestring and parameter file call string for this behavior is "StochasticGapGrowth". Note that this behavior does not descend from clGrowthBase. There is nothing to be gained from that association, and it is easier for this behavior to perform all of its work at once rather than on one tree at a time.

It is a fatal error if this behavior cannot find the "Gap Light" grid during setup.

Constructor & Destructor Documentation

◆ clStochasticGapGrowth()

clStochasticGapGrowth::clStochasticGapGrowth ( clSimManager p_oSimManager)

Constructor.

Sets the namestring.

◆ ~clStochasticGapGrowth()

clStochasticGapGrowth::~clStochasticGapGrowth ( )

Destructor.

Frees memory.

Member Function Documentation

◆ Action()

void clStochasticGapGrowth::Action ( )
virtual

Performs growth calculations.

This function cycles through all of the trees twice. On the first pass, each tree is assigned to the appropriate cell in "Growth Counter". If that cell has gap status, the number in the "Current" data member is incremented. If the cell does not have gap status, nothing happens. Then, for each cell in "Growth Counter" that has a positive count in "Current", a random number is multiplied by it and that number is placed in "Target". Then the trees are cycled through again in exactly the same way. For each cell, when the tree number in "Target" has been reached, that tree is allowed to grow to adult status.

Reimplemented from clBehaviorBase.

◆ GetData()

void clStochasticGapGrowth::GetData ( xercesc::DOMDocument *  p_oDoc)
virtual

Does the setup for this behavior.

This gets a pointer to the "Gap Light" grid and sets up the "Growth Counter" grid. Then it populates the mp_bAppliedTo array. Then it sets up the query for doing tree searches.

Parameters
p_oDocParsed parameter file.
Exceptions
modelErrif the "Gap Light" grid cannot be found.

Implements clWorkerBase.

Member Data Documentation

◆ m_cQuery

char* clStochasticGapGrowth::m_cQuery
protected

Query for finding trees to which this behavior applies.

This will instigate a species/type search for all the species and types to which this behavior applies.

◆ m_iCurrentCode

short int clStochasticGapGrowth::m_iCurrentCode
protected

Data member code for the "Current" int data member of the "Growth Counter" grid.

◆ m_iIsGapCode

short int clStochasticGapGrowth::m_iIsGapCode
protected

Data member code for the "Is Gap" bool data member of the "Gap Light" grid.

◆ m_iNumSpecies

int clStochasticGapGrowth::m_iNumSpecies
protected

Keep a copy of this for the destructor for freeing memory.

◆ m_iTargetCode

short int clStochasticGapGrowth::m_iTargetCode
protected

Data member code for the "Target" int data member of the "Growth Counter" grid.

◆ mp_bAppliedTo

bool** clStochasticGapGrowth::mp_bAppliedTo
protected

Array for determining to which trees this behavior is applied.

The array size is # total species by # total types.

◆ mp_oGapLight

clGrid* clStochasticGapGrowth::mp_oGapLight
protected

Pointer to the "Gap Light" grid (this behavior does not create this grid).

This grid is expected to have one bool data member called "Is Gap".

◆ mp_oGrowthCounter

clGrid* clStochasticGapGrowth::mp_oGrowthCounter
protected

Grid called "Growth Counter", created by this behavior.

It has a grid cell resolution matching "Gap Light". It has two int data members, "Current" (which holds the number of trees found in gap cells) and "Target" (which holds the target number of the tree, out of the total in "Current", which has been chosen to grow). Any map of this grid entered in the parameter file will be ignored, including just setting the grid cell resolution.
