Временная динамика флор техногенных территорий юго-востока Украины

Abstract

As a result of comparative studying different-time states of florae from various technogenous territories of the south-east of Ukraine, some regularities of their time dynamics for 40-year period have been revealed. By means of multi-dimensional statistics it was determined that florae forming as a result of technogenous impact have significant differences and they are divided into separate groups: florae of quarry-mine dump type, ash dumps florae and industrial sites florae. Florae of quarrydump territories are the most dynamic ones which develop according to autogenic-successional type. Comparatively to them, ash dump florae are more rigidly determined by anthropogenic conditions and are changed not in such rates. The most expressed dynamics and structures variability in the process of their development are observed in respect to participation degree of adventive species, euapophyte species, hemiapophytes and occasional apophytes. The least expressed dynamics and florae variability are fixed in respect to flora structure relatively to life environment.
