Based on the pilot work on sustainable forest managemnt, this paper focuses on the framework of sustainable forest management system and the approaches for developing such a system and suggests that good jobs shuld be done in building a platform, coordinating two relations, carrying out three activities and using well four mechanisms. Building a platform means that a forest resources management information system shall be established; coordinating two relations is that the relation between commercial forest management and their ecological management and the relation between public welfare forest protection and management shall be coordinated well, aiming at maximizing overall benefits of forests; Carrying out three activities indicates that county-level planning for sustainable forest management, forest management plan, diverse forest management practices and sustainable forest management technical system shall be developed; Using four mechanisms suggests that the market mechanism, the government readjustment mechanism, the internal mechanism of forest ecosystem and the forest property right mechanism shall be made good use of. Meanwhile, focusing on the realistic situation, the paper has a good look at several issues to be addressed in the pilot work on sustainable forest management.

Richard,Logistic,Korf,Mitscherlich,Schumacher,Weibull equations were used to simulate individual tree height growth of Pinus tabulaeformis plantation with different site indexes.The result showed that simulative precision of three parameters growth equations(Logistic,Weibull,Richard,Korf)were similar,and were significantly higher than those of the two parameters equation(Mitscherlich,Schumacher equation);Effect of site indexes on the progressive line parameters and shape parameters of the equation was significant.Individual tree height growth model of Pinus tabulaeformis plantations was constructed with the site indexes.The best forecast equation was the Logistic equation. Using some data of Pinus tabulaeformis plantation plot that are not used for building models to test,the result showed that the measured values and simulated values of height had no significant difference(p=0.6213>0.05).Therefore,the equation was able to predict accurately height growth of Pinus tabulaeformis plantation,and provide an important reference for Pinus tabulaeformis plantation management.

This study was performed by using dead branches and knot size analysis data of 50 sample trees in 10 sample plots for Larix olgensis Hengy plantations with different ages, different stand density and different sites. The data statistical analysis and matrixes and simulating technique are uses for analyzing and studying the distribution of the knot size along the stem. The models of predicting knot size were established. The results indicate: (1) the knot diameter increases with the knot height and reaches limit value at the tree crown base. The knot diameter can be described with Mitscherlich equation. (2) below 40% of the tree, the sound knot length increases along with the height of living locations of the knot, then the trend tends to decrease.(3) the loose knot length increases with the increasing of tree diameter at breast height and decreases with the increasing of knot angle.

Using Hegyi’ s competition index model for individual tree,we analyse the intraspecific and interspecific competition of Picea crassifolia in Liancheng National Nature Reserve of Gansu.The results show that intraspecific competition intensity of Picea crassifolia reduced with increase in diameter scale of the trees.The intraspecific competition is more bigger than interspecific competition.The order of competition intensity(CI)is:Picea crassifolia>Picea wilsonii>Acer tetramerum var.betulifolium>Populus davidiana>Betula albo-sinensis>Salix sp.The relationship between competition intensity and individual growth of objecttive tree follows closely the equation CI=AD^-B.When the diameter scale reaches 45 cm,there is little change of competition intensity.The CI of Picea crassifolia has plus correlation with altitude and crown density.
