Abstract

Regarding the parabola density effect model as presupposition , in accordance with the growing traits of the planted timber forests , the paper finds density control model by optimal control method and finds the solution with dynamic programming .The model has the characteristics with variable power times , stronger adaptability , mobile thinning interval and convenient use .The model is used in masson pine planted timber forests in Guizhou Province .The outcome shows that the computing results tall with the growing law of the planted timber forests , and accord with practical experiment .
- optimal control,
- dynamic programming,
- mobile interval planted timber forests,
- stand density,
