山东伟德山林木种质资源初步研究

为系统研究伟德山的生物概况，通过样地、样线法对其木本植物种质资源进行了调查。结果表明，伟德山种质资源较为丰富，共有木本植物（乔木、灌木、亚灌木）269种，隶属70科151属。其中乔木类139种，灌木及藤本植物130种；珍稀濒危特有物种19种。优势科、单属单种科的分布规律符合暖温带气候特点；植被中温带成分优势明显，热带成分占有一定比例；群落中灌木层的组成优势明显。维管植物中世界分布属、温带分布属、热带分布属均有分布。并从加大种质资源生物学研究力度、建立野生植物开发利用试验站、建设原地和异地保护区、合理划分功能区、发展周边经济等方面，提出了伟德山木本植物种质资源保护及可持续发展的建议。

A Preliminary Study on Woody Germplasm Resources in Weide Mountain

To study the biological situation in Weide Mountain, woody germplasm resources were investigated by sample plot and sample line method. The results showed that the woody germplasm resources were rich in this area. There were about 269 species of woody plants (trees, shrubs, bushes) in the mountain, belonging to 70 families, 151 genera. Among the plants, there were 139 tree species, 130 species of shrubs and vines, and 19 rare and endangered endemic species. The distributional law of dominant families and families with single species, single genus conformed to the warm temperate zone climate characteristics. In vegetation, temperate zone element was obvious, the tropical one occupied certain proportion. Shrub layer took up obvious advantages in community. The international distributional genera, temperate ones, tropical ones all had distribution in vascular plants. Based on this, we put forward suggestions for the protection and sustainable development of woody germplasm resources as increasing investigative efforts of germplasm biology, setting up test station for development and utilization of wild plants, establishing in situ and foreign reserves, classifying functional zone rationally, and developing peripheral economy.
