湖北大别山区低效马尾松林评判与调控

Evaluation and Regulation on Low Efficiency Masson Pine Forest in Dabie Mountain of Hubei Province

摘要:

摘要：在查阅相关文献资料并结合样地调查的基础上，对湖北大别山区现有马尾松林类型与特征、马尾松林演替过程及低效马尾松林判别和调控技术等内容进行了分析和论述：①将湖北大别山区马尾松林分为2个类型组、12个类型；②湖北大别山区马尾松林群落演替可分为4个阶段，处于向地带性植被渐进过渡的群落类型，具有不稳定性；③选择立地因子和林分结构因子等6个指标，将马尾松林分质量划分为5个等级，其中1,2级为良，3级中等，4,5级为差；④在分析湖北大别山区马尾松林演替规律及群落树种生长特性基础上，结合当地马尾松林的经营目标，制定了低效马尾松林调控技术流程，提出了具体的调控技术措施。

Abstract:Based on the extensive investigation and sample survey, we have analyzed and discussed the existing masson pine forest types and characteristics, the process of succession and evaluation and regulation on low efficiency Masson pine forest and so on. The results showed that①Masson pine forest was divided into 2 types groups and 12 types in Dabie Mountain of Hubei Province; ② Community succession of Masson pine forest can be divided into four stages in Dabie Mountain of Hubei Province, which is in a gradual transition to the zonal vegetation community types, and has the characteristics of instability; ③We selected 6 indicators including site factor and stand structure factor and other factors, and then the Masson pine stand quality was divided into 5 grades, which first and second grade was good, third grade medium, fourth and fifth grade was worse; ④Based on the community tree growth characteristics and succession laws of Masson pine forest in Dabie Mountain of Hubei Province, combined with the local Masson pine forest management objectives, we formulated the low efficiency Masson pine forest regulation technology process, and put forwarded specific technical measures.
