THE COMPLEX APPROACH IN APPRAISAL OF THE CONDITIONS OF NATURAL ECOSYSTEMS IN THE laquo; VALLEY raquo; ZONE USED FOR THE STORAGE OF CHEMICAL WEAPONS (POCHEP, BRYANSK REGION)

摘要

Research was carried out on the ecological situation in 2001 on the territory of the largest arsenal of chemical weapons, in the Pochep region of Bryansk area. These chemical weapons are an agent dispersal ammunition, which is filled with nerve agent. The complex method was used in the analysis of natural ecosystems. Bioindicators of the state of environment were chosen among the components of forest ecosystems such as: standing timber of a Scotch pine (Pinus silvestris L.); fir-tree (Picea abies (L.) Karst). oak (Quercus robur L.), regrowth. undergrowth, topsoil growth, soil mesofauna, ornithofauna, amphibians, assemblage of epiphyllous lichen, the pollen of a Scotch pine and also agrocenosises. The system of local ecological monitoring was established on the territory of the arsenal «Valley». The system is based on 23 permanent trial areas. On the whole, no negative influence of the arsenal of chemical weapons on the components of natural ecosystems was revealed. Marked negative changes of separate indices are caused by the influence of additional technogenic and anthropogenic factors.
