1. This paper discusses the mission of developing a silviculture DSS system for small forests owners, and designs and builds a SDSS based on silviculture plans and economic analysis.

2. We believe that the discipline of silviculture needs further guidance from the system sciences.

3. And the effects of the site type, silviculture density and stand age on the above indexes are studied.

4. Control methods were offered such as silviculture, quarantine, biological and chemical control.

5. It points out that the output value of silviculture of artificial timber stand should be divided into two parts, the output value of stumpage and the output value of cultivability.

6. The precision of silviculture technologies is essential for plantation establishment and management, for high efficient utility of limited land and environment resources.

7. The silviculture funding mechanism has made an important effect on the long-term and sustainable development of state-owned forest farm.

8. A silviculture study on large scale improvements of a man-made cryptomeria (Cryptomeria japonica) forest was done to establish a multi-storied plantation.

9. A silviculture study on large scale improvements a man - made cryptomeria a multi - storied plantation.

10. Site type and stand age can significantly influence the paper properties whereas silviculture density effect isn't significant yet.

11. In this paper, two concepts calculated price of output value and coefficient of increment are put forward, with which the problem of calculating output value of silviculture is solved in theory.

12. The share based on land is considered part of the cost of silviculture from the whole sector's point of view.

13. Tetraploids locust is expected to become the first selection species in silviculture and regeneration in the south of Liaoning Province.

14. After that measures for implementing the strategy are put forward in the aspects poplar silviculture, poplar wood processing and relevant policies.

15. Calculating output value of silvieulture must follow the general principles of output value calculation and reflects the particularities of silviculture production.

16. It is showed that all sorts of growing and culturing methods in intensive culturing management can be combined to control wood quality through silviculture interaction.

17. As a branch discipline of ecology to study the relationship between forest and its environment, forest ecology is a foundation for silviculture, forest management and protection.

18. The present situations and management models of seedling production, silviculture and fire prevention in Turkey were described.

18. try its best to gather and build good sentences.

19. The lower limit of forest price should be determined by the current cost of silviculture and reevaluation of capital.

20. The signification, representation, current status and realization approaches of the precision of silviculture technologies are analyzed.
