Abstract

The Kouh-payeh with an area of 3000 km2 is located at 70 km east of Isfahan on the edge of central Kavir at longitude 52° 26ʹE and latitude 32° 43ʹN. In this study, the floristic richness, life form, geographical distribution and conservation status were assessed. All plant species were collected from Kouh-payeh area during 2014-2016. The collected species were identified, then life forms and chorology of each species were estimated. By examining a total of 200 collected plant species, 38 families and 137 genera were found. The dominant life forms were mainly identified as therophytes (45%) and hemicryptophytes (34%). Based on chorotype information, an Irano-Touranian distribution (60%) was generally observed in this area. Other chorotypes such as Irano-Touranian/Saharo-Sindian (6%) and Irano-Touranian/ Euro-Siberian (6%) were present in lower quantities. Among the identified species, 43 endemic species were also recognized. In terms of conservation status, there were Low Risk (77%), Vulnerable (15%) and Data Deficient (8%) needed some conservation policies. This study was performed for the first time in this area.
伊朗伊斯法罕省Kouh-payeh地区植物区系研究、生命形式和年代
Kouh-payeh面积3000平方公里,位于伊斯法罕以东70公里,位于卡维尔中部边缘,东经52°26′E,北纬32°43′N。本研究对植物区系丰富度、生命形式、地理分布和保护现状进行了评价。所有植物种类于2014-2016年在Kouh-payeh地区采集。对收集到的物种进行鉴定,然后对每个物种的生命形式和演化史进行估计。通过对采集到的200种植物进行分析,鉴定出38科137属。优势生活型主要为植生型(45%)和半隐生型(34%)。根据菌型资料,该地区普遍呈伊诺-图拉尼亚分布(60%)。其他菌种如伊诺-图拉尼亚/萨哈拉-辛印度(6%)和伊诺-图拉尼亚/欧洲-西伯利亚(6%)的数量较少。在已鉴定的种中,还发现了43种特有种。从保护状况来看,需要采取保护政策的有低风险(77%)、脆弱(15%)和数据不足(8%)。本研究在该地区尚属首次。
