Pedogenesis and soil classification in relation with plant cover in a part of northern forests ecosystem of Iran, Case study; Vaz experimental forest

The north forests ecosystem of Iran having unique hyrcanian characteristics is one of the most important plant diversity due to altitudinal changes caused exclusive soil with evident differences comparing with other regions was formed in this ecosystem. This study along with recognizing important soil types due to plant cover was accomplished in Vaz experimental forest where has located in the north forests of Iran. So work units were segregated based on geomorphology, geology, plant cover and etc, and soii base -map was prepared, then a profile were dug in the place of each unig of this map on the ground. The changes of plant cover regarded as the most important indicator , 7 profiles among 27 ones were recognized through phys-chemical analysis and after final conclusion. This study was performed at the framework of optimal natural resources management project in Vaz experimental forest, acqired results showed that beside plant cover changes in soil types, altitudinal and slope changes have an important role in pedogenesis and transformation of regions soils.
