Проаналізовано особливості виникнення та розміщення дрібних форм фітогенного рельєфу в межах Українського Полісся. Зокрема, досліджено такі фітогенні форми рельєфу, як купини, мохові горбки, дерново-трав"янисті горбки та пасма, пікогорбки утворені грибами, імпактні "мікрократери" і "ходи" коренів рослин.. Охарактеризовано їх морфологічні і морфометричні особливості та щільність розташування у межах окремих ділянок дослідженої території.
Large numbers of accumulative and denudation biogenic relief forms are frequently found within the territory of Ukrainian Polissia. Their sizes have the rank of pico-, nano- and microrelief - tussocks, moss bumps, sod-grassy bumps and ridges, impact microcraters etc. This is due to the fact that the natural conditionsof the investigated area are favorable for their appearance.
Thus, the average height of tussocks on the grassy marshes is 10-12 cm and the diameter is 25-30 cm. In some cases, the height of tussocks can reach 40 cm with the diameter of 70 cm. Density of tussocks may reach more than a hundred units of 10 m? in some marshy massifs. The number and density of tussocks in areas occupied by meadow plants is considerably less than on the marshes. Here their number can vary from a few units to several doz&en per 1 hectare.
Moss hills, the core of which is the old earth molehills or small anthills, are also frequently found within the explored area. These forms of phytogenous relief have a considerably wider geography than tussocks, but their density &is insignificant - usually a few pieces per hectare. The height of moss hills is usually 15-20 cm and the diameter is 20-30 cm.
Impact microcraters are also distinguished among woodlands (from the English "impact" - blow, collision). These are isola&ted nanorelief forms which appear during windbreaks as the result of hitting the Earth"s surface by broken trunks and large branches of trees. In most cases, they have round or oval shape. Their depth ranges from 5 to 30 cm and they have the diameter& of 15-20 cm.
Sod-grassy mounds and ridges are met on forest edges, clearings, meadows, parks and fields. Sod-grassy mounds are low (usually 10 cm) hills of round shape while ridges are elongated mounds with approximately the same height and the len>h up to several meters.
"Walks" of plant roots and picohills also belong to small relief forms of Polissia territory. Their length can reach several meters and the diameter ranges from a share of millimeter to several centimeters. Picohills are fo&rmed by fungi in the process of their growth.
Проанализированы особенности возникновения и размещения мелких форм фитогенного рельефа в пределах Украинского Полесья. В частности, исследованы такие фитогенние формы рельефа, как болотные кочки, моховы&е холмики, дерново-травянистые холмики и микрогряды, пикохолмики образованные грибами, импактные "микрократеры", а также "ходы" корней ростений. Дана характеристика их морфологических и морфометрических особенностей и плотности розмещения в пределах &отдельных участков исследованной территории.
