This article substantiates the need to organize a system of ecological
normalization of anthropogenic loads on natural complexes that is fun
damentally different from the sanitary-hygienic approach. The distinct
iveness of the problem is determined by the fact that biological syste
ms of supraorganism rank are considered as the object of normalization
. ln this regard, the problem of stability of ecological systems and t
he possibility of their existence in several metastable states is of s
pecial significance. The role of temporal dynamics of natural systems,
and the presence of evolutionary, historical, and current scales of s
uccession phenomena are discussed. Along with this, the spatial inhomo
geneity of ecological systems and their possible spatial dynamics have
to be taken into account in determining the permissible anthropogenic
load.
