Sustainable Army Training Lands/Carrying Capacity: Training Use Distribution Model (TUDM)

摘要

Since the early 1980's, researchers and land managers from ERDC/CERL have been developing means to quantify and predict sustainable vehicle use rates associated with maneuver training exercises for Army training lands. Two new projects include: (1) Army Training and Testing Areas Carrying Capacity model (ATTACC), and (2) the Ecological Dynamics Simulation model (EDYS). To incorporate the effects of maneuver impacts as ecological stressors into the EDYS model, researchers developed the distribution pattern ideas used within ATTACC and incorporated them into a CIS environment to allow for long-term distribution and intensity estimations. The product resulting from this effort is the Training Use Distribution Model (TUDM). The TUDM was developed to provide long-term predictions of distributions and intensities of off-road Army maneuver-training impact for carrying capacity and other ecological simulation models. This report contains an in-depth description of TUDM structure and architecture, along with the individual components. Validation studies indicate reasonable results in terms of predicting locational disturbance magnitudes, given the resolution of data used to calibrate the model. Results also indicate that the disturbance patterns modeled generally match the overall landscape pattern found on the maneuver training lands.
