摘要
对山东特有树种资源的种类、地理分布、群体数量、生态区位等进行了调查。调查统计发现:山东省有特有树种10种5变种,这些种类分布区狭窄,仅4种分布于2~3个分布点,其余只分布在一个地市;种群数量有限,其中泰山椴、少叶花楸种群数量500余株,山东栒子、鲁中柳数量为100~500株,山东山楂等8个树种资源种群数量均不足10株,亟需加强保护。同时对这些资源的濒危等级进行了划分,极危(CR)12种、濒危(EN)2种、易危(VU)1种。此次调查为深入研究和开发山东林木种质资源提供了参考。
According to the survey and statistics, there were 10 species and 5 varieties of endemic tree species in Shandong Province. The geographical distribution, population quantity and ecological niche of those were investigated. It was found that only 4 species were scattered in 2- 3 distribution points, and the rest were only distributed in one point. The populations were small, the number of Tilia taishanensis and Sorbus hupehensis var. paucijuga was more than 500, and the number of Cotoneaster schantungensis and Salix luzhongensis was 100-500. The number of 8 tree species such as Crataegus shandongensis were less than 10. Protection should be strengthened desperately.Meanwhile, the endangered grades of those resources were divided: 12 species were critically endangered (CR), 10 were endangered (EN), and one was vulnerable (VU). The investigation provided reference for research and development of Shandong forest germplasm resources.
