Effects of various ecological factors on process-based ecological model behavior uncertainty

cological forecasting predicts the effects of environmental changes on ecosystemstate and activity. At present, technologically

comprehensive forecasting estimates are estimated using process-based ecological models. However, it is difficult to

isolate the ecological factors that cause models behavior uncertainty. To solve this problem, this study aimed to construct

an ecoinformatic diagnostic framework to explain uncertainty in model behavior with respect to both the mechanisms and

algorithms involved in ecological forecasting. We introduce a complicated ecological driving mechanism to the process-based

ecological model using analytical software and algorithms. The ecological forecasting study involved three components: (1)

model-observation validation, (2) diagnostic framework, and (3) temporal and spatial forecasting methods. Subsequently, as a

case study, we apply the diagnostic framework to detect

biomass forest patches at a regional scale (196,158 ha) using

the 3PG2 (Physiological Principles in Predicting Growth) model. Our results show that this technique improves the accuracy of

ecological simulation for ecological forecasting and prevents new uncertainties from being produced by adding a new driving

mechanism to the original model structure. We achieved the highest cost performance ratio between the accuracy requirement

of model simulation and the availability of observation data. This result was supported by our

using the 3PG2 model, in which ecological factors caused 21.83% and 9.05% uncertainty in model behavior temporal and

spatial forecasting, respectively. In conclusion, the systematic ecoinformatic diagnostic framework developed here provides a

new method that could be applied to research requiring comprehensive ecological forecasting.
