混交林初期生长效益分析——以杉木及阔叶树混交林为例

Initial Growth Benefit Analysis of Mixed Forest—A Case Study of Mixed Forest of Cunninghamia lanceolata and Broad-Leaved Trees

为有效利用森林资源,提高森林资源的使用效率,促进我国经济建设的快速发展,开展了各种类型的混交林经营活动,旨在有效提高森林资源的使用效率。以杉木与阔叶树混交林以及杉木纯林为例,对其初期生长效益进行了分析,结果表明:不同类型混交林之间在生长、林分生产力、蓄积量等方面都具有一定的差异性,同时还可以充分利用不同类型混交林之间的差异性来提高林分生产力和林木蓄积量。

Forest resources are the important material basis of social development.With the continuous development of China's economic construction,the construction of forestry industry plays an important role in forestry ecosystem,forestry social system and other aspects.In order to make effective use of forest resources,improve the efficiency of forest resources and promote the rapid development of China's economic construction,various types of mixed forest management activities are carried out to effectively improve the efficiency of forest resources.This paper takes the mixed Cunninghamia lanceolata and broad-leaved forest as an example to analyze the initial growth benefits,and the results show that there are certain differences in growth,stand productivity and stock between different types of mixed forests,and the differences between different types of mixed forests can be used to improve stand productivity and forest stock.
