Since the reform on the system of collective forest rights was carried out,great changes have taken place in foresters’ demand for forestry science and technology.Therefore,the traditional promotion means should be re-examined and changed.The paper explores the ways and means of promoting forestry science and technology in the aspects of promoters,promotion project establishment,promotion agencies,effect feedback,supervision and management.(i)After the reform on the system of collective forest rights was carried out,foresters’ demand for forestry science tends to diversify.Specialized forestry cooperatives have joined in the ranks of promotion targets,which helps to boost the development of specialized forestry cooperatives and will intensively satisfy foresters’ needs for forestry science and technology as well.(ii)Promotion projects should be classified based on the economic level in the local areas.In underdeveloped areas projects of economic efficiency should be promoted while in developed areas projects of ecological efficiency should also be promoted besides projects of economic efficiency.Reserve pools of forestry promotion projects should be created for foresters.(iii)The two-way choice system for both promotion agencies and promotion targets should be established and means of participatory promotion should be carried out.The mechanism for promotion agency certification and identification should be implemented.The market-dominated promotion system can be set up.(iv)The mechanism for scientific research project initiation and evaluation should be improved and one of the key evaluation criterions is whether the project is valuable and practical.(v)Forestry science and technology promotion should be combined with forestry industrialization,import and export trade of forest products,dealing with green trade barrier and construction of the technical norm system for forest products so as to enhance the gross value of output in forestry sector,scientific and technological content of forest products and international competitiveness as well.

The interspecific associations of tree species into forest management planning models have become increasingly important in sustainable forest management.Tree selection is one of the important factors of designing forest management plans.In order to study the interspecific associations of tree species affecting the adaptation of plant communities in the process of forest management,we survey 238 sample plots’ data on Masson pine plantation forest in Guangxi Province.A series of techniques including the VR analysis,χ²-test,Pearson correlation coefficient test,Spearman rank correlation coefficient test and Ochiai were used together to analyze the interspecific associations of dominant species.The results indicated that the dominant populations had general positive interspecific association,but the species pairs with significant positive associations were only ten percent of the total 190 species pairs,and most of the species pairs showed weak interspecific association.The interactions among the tree species were generally found to be complementary,yet sometimes contradictory.It was more practical for forest management from the view of multiple interspecific association and tree species selection,instead of a single species.Our study highlights the importance of having a good understanding of the tree selection of target stand as a basis for making decisions regarding forest management.
