迭部林区森林植物特性研究(一)

Studies on the Special Characteristics of Forest Vegetation in Diebu County (1)

迭部林区是甘肃省木材生产的主要基地。境内峰峦叠障,气候温凉湿润,森林植物资源丰富。本文根据作者近几年的调查研究,首次报导了该区种子植物组成情况。建群种系可分为9个植被型,11个群系组,42个群系;以虎头山和苏伊亚黑山为例,揭示了该区森林植物垂直带谱、本区产9种国家重点保护植物分布情况以及5种甘肃分布新记录。

Diebu forest is the main wood-production base in Gansu province. Within this area, there are numerous ridges and peaks; the climate is mild, cool and moist; the forest coverage attains 54.4%; the forest plant resource is plentiful. The spermatophyte is composed ofmore than 60 families of Rosaceae, Leguminosae, Ranunculaceae and so on. According to the investigation and research by the authors in the last few years, this paper reports the spermatophyte composition of Diebu forest for the first time. The edificato series could be divided into 9 vegetation types, 11 formation groups and 42 formations. Based on the data from Hutou Mt. and Suyiyahei Mt., the spectrum of the forest verticle zone was demonstrated, the distribution of 9 special plants conserved by our country was reported, and 5 species were first recorded in Gansu province.
