山东茶山高等植物资源及群落结构

目的:为有效保护和合理利用山东茶山国家级生态示范区植物资源提供科学依据.方法:对茶山进行了植物物种综合普查,调查范围涉及植物物种及野外分布、群落结构和区系组成.结果:记录到高等植物352种,隶属90科250属,其中国家二级重点保护植物4种.本区地带性植被为黑松人工林及次生杂木林,主要森林植被为黑松群落Pinus thunbergii community.其植物区系以热带分布类型和温带分布类型为主,纬度因素和"岛屿效应"应是形成该格局的主要成因.受强烈人为活动干扰,该区域原生植被类型已遭严重破坏,珍稀植物灭绝风险很高.结论:调查表明该区域群落结构简单,灌木层和层间结构不发达,群落演替时间短.

Higher Plants Resources and Community Structure in Tea Mountain of Shandong Province, China

Objective: The research is to provide the basis for effective protection and wise utilization of the plants resources inTea Mountain National Ecological Demonstration Area of Shandong Province. Methods: The general investigation on plant species inTea Mountain was conducted. The research scope covered plant species, their distribution in wild, community structure and flora.Results: A total of 352 higher plants, belonging to 250 genera and 90 families, were recorded. Four species were listed as nationalsecond-grade protected plants. Regional vegetation is Pinus thunbergii plantation and Secondary forest. The main forest vegetation isPinus thunbergii community. Pantropic types and N. Tem types are dominant types. The latitude and "the islands-effect" should be themajor-effect factor of this pattern. Because of intense artificial active disturbance, primary vegetation types in this region have sufferedserious destruction, especially the rare and precious plants that are at high risk of dying out. Conclusions: This regional communitystructure is simple. The shrub layer and the liana layer are undeveloped. The syngenesis time is short.
