摘要

植物区系研究是获得生态系统中植物遗传资源的生物能力以及管理和保护知识的最有效方法之一。赞詹县位于山区,面积6763平方公里,平均海拔1663米。其良好的植被多样性是该地区适宜的生态条件、多样的栖息地和适宜的水资源的结果。赞詹县城中心区面积2600.2平方公里,是展示树木和木本灌木物种多样性的代表。为了鉴定树木和灌木的种类、生命形式和植物的合唱,通过传统的区系研究方法收集样本,然后使用分类学参考文献进行鉴定。研究区共有乔木和木本灌木122种,隶属于39科76属。最丰富的科包括蔷薇科(29种)和木犀科(9种),占乔木和木本灌木的31.15%。用Raunkiaer方法测定,中显生植物(37.7%)和微植物(32.79%)是该地区的主要生命形式。根据Zohary方法,Irano Turanian植物元素是该地区最重要的元素。李被发现是伊朗的特有植物。

The introduction of tree and shrub species in the central district of Zanjan county town
Floristic study is one of the most efficient methods of gaining knowledge about biological capacities, as well as management and conservation of plant genetic resources in ecological systems. Zanjan county town is located in a mountainous region with an area of 6763 km2 and the average altitude of 1663 m.a.s.l. Its favorable vegetation diversity is the result of suitable ecological conditions, diverse habitats and appropriate water resources in the region. The central district of Zanjan county town, with an area of 2600.2 km2, was chosen as a representative to show tree and woody shrub species diversity. In order to identify tree and shrub species, life forms and chorology of plants, samples were collected by the conventional method of floristic studies and were, then, identified using taxonomic references. In total, there were 122 tree and woody shrub species, belonging to 76 genera and 39 families, in the studied area. The richest families included Rosaceae (29 species) and Oleaceae (9 species), which comprised 31.15% of the arboreal and woody shrub species. Mesophanerophytes (37.7%) and microphanerophytes (32.79%) were the dominant life forms in the area studied as determined by the Raunkiaer method. The Irano-Turanian vegetative elements were the most important elements in this area based on Zohary approach. Prunus lycioides was found to be endemic to Iran.
