Larch-spruce-fir matrix growth model.

Multiple-species nonlinear matrix growth model was developed for Larch-spruce-fir forests in Jingouling forest farm, Wangqing forestry bureau, Jilin province, northeastern China. The model was validated in short term by comparing the observed with predicted number of trees in each diameter class and species group, and was statistically reasonable and subsequently was applied to predict timber yield, tree species diversity, tree size diversity, and aboveground carbon storage under different management scenarios. The matrix model is a valuable tool for simulations of forest management scenarios.
