| The storage pool (Abbandan), as a system of rainwater catchment systems, have many positive environmental effects and has been very important for the agricultural life and natural resources of the northern regions of Iran. On the other hand, soil is one of the important elements of natural ecosystems, which plays an important role in the distribution of plants. This research was carried out with the aim of investigating the characteristics of the soil and vegetation in the area of the storage pool in the south of Langarud city and the heights overlooking it. Plant samples were collected from storage pools, lowlands and plains around them and forest areas overlooking it during the growing season of 2022. Soil samples were also taken from the surface horizon of different altitudes from -20 to 325 meters above sea level (m.a.s.l.), and some of their physical and chemical properties were measured. Of 250 plant samples collected, 146 taxa were identified, which belonged to 60 families, 127 genera and 146 plant species. Investigating the characteristics of the soil and habitat of these plants shows the uniformity of the soil texture (medium to light class) and the electrical conductivity (EC) is less than 1 (dS/m). The lack of salinity problem is due to the very humid climate and the occurrence of more than 1400 mm of annual rainfall in the region. In different altitude gradients, soil pH ranged from neutral (6.78) to strongly acidic (4.03). The pH of the soil decreased with the increase in altitude. The range of organic carbon was in the medium to optimal class and the amount of N-P-K fertile elements was in the medium to rich class. In this study, the homogeneity of many physical and chemical characteristics of the soil, except for pH, was observed in different parts of the study area. In general, it can be said that the soils in the study area have no restrictions for the establishment of vegetation and the relatively high species diversity in this area confirms this. |
