| Abstract: | Based on the theory of variable density total stand prediction model, the empirical equation of positional index and stand density index of Pinus sylvestris var. mongolica plantation were established,combined with the dynamic prediction model of stand density, the basal area prediction model and the volume prediction model of P.sylvestris var. mongolica plantation were established.The error between the predicted value and the measured value was 3.64%, and the precision of the model was 96.37%. |
| Keywords: | Pinus sylvestris var. mongolica Stock volume Prediction model |
