Edaphic regimes of intrazonal forest ecosystems of small rivers’ terraces of the northern part of Steppe zone of Ukraine

Results on phytoindication research of native and anthropogenically transformed small insular aspen-birch woods (koloks) are under consideration. Parameters of the ground moisture, saline, acidity and nitrogen regimes, humus content for different types of koloks are presented. The directions of hydrogenic and trophogenic changes for intrazonal ecosystems in dependence of forming condition are given.
