Forest reserve of Ghasemloo valley (Shohada) and it's adjacent areas with 577 hectare surface area has located in south of Urmia and is known as an important natural plant station of Urmia. It is studied with respect the important factors which influencing vegetation cover in whole, particularly, with refer to composition and Formation of plant communities. To study the area, Brown-Blanquet's method was used. Plant samples were collected from 77 sample plots. The study resulted in recognition of four herbaceous types and seven shrub communities in study area. In addition, the investigation led to the fact that the most important factors which influencing the vegetation cover, are: geographical orientation, altitude, gradient and soil texture. More over, the study also resulted to preparation ofa colour vegetation map with 1/20000 scale.
加塞姆卢山谷（烈士谷）森林保护区及其毗邻地区，表面积为577公顷，位于乌尔米耶以南，是乌尔米耶一个重要的天然植物站。对影响整个植被覆盖的重要因素进行了研究，特别是参考了植物群落的组成和形成。为研究该地区，采用了布朗-布朗凯方法。从77个样地采集了植物样本。研究结果识别出研究区域内的四种草本类型和七个灌木群落。此外，调查发现影响植被覆盖的最重要因素是：地理方位、海拔、坡度和土壤质地。此外，该研究还绘制了一幅比例尺为1:20000的彩色植被图。
