河南省林种结构调整的研究

Study on lmprovilng Forest Category Structure in Henen

根据１９９３年省森林资源清查、森林资源消耗量及消耗结构的调查资料，以可持续发展的理论为指导，采用线性规划对我省的林种结构进行了研究。研究结果：河南省现阶段的林种结构应为：用材林∶防护林∶经济林∶薪炭林∶特用林＝３４９∶１５９∶２３７∶２１１∶４４。

Based on many data,such as Henan forest resources inventory in 1993,Henan forest resources consume volume and structure, etc. Directed by the theory of sustainable development. The paper studies Henan forest category through using linear programing the results indicate that Henan forest category structure shoulde be: 34 9 percent of timer forests, 15 9,percent of protective forests , 23 7 percent of plantations of economic plants ,21 1 percent of fuelwood forests,4 4 percent of forests for special purposes.
