| Abstract: | The principle and algorithm of Ensemble Kalman filtering are introduced, and taking the 1950 - 1998 five forest census data as samples, the estimation and prediction of dynamic forest area is made by using Ensemble kalman filtering. The results showed that, using Ensemble kalman filtering for prediction of forest resources is a better forest resources prediction method. |
