混交林具有许多优点,既可以防止火灾、病虫灾害,又可以增强水土保持、改良土壤、合理利用土地、增产木材,所以营造混交林是提高森林质量的最好方法之一。但目前对如何正确配置混交树种还缺乏经验,而生产上又迫切需要解决这方面的问题,因此我们特对我省比较普遍的几种混交林进行了调查,以便了解混交树种之间的关系,作为今后选择混交树种和决定混交方法的参考。 Mixed forest has many advantages, which can prevent fire, pests and diseases, enhance soil and water conservation, improve soil, make rational use of land and increase timber production. Therefore, to create mixed forest is one of the best ways to improve forest quality. However, there is still a lack of experience on how to correctly allocate hybrid tree species. However, there is an urgent need to solve this problem in production. Therefore, we conducted a survey on several mixed forest types that are relatively common in our province in order to understand the relationship between tree species, As a future choice of mixed tree species and decide the method of mixed reference.
