Abstract. The article deals with the tow opposite and at the same time partly crossing tendencies in the postmodern world which greatly enforce the heterogeneity of national cultures, that is hybridisation and enclavisation.
 
Great number of isolated enclaves differ from each other form the specific “conglomerative” decentralised cultural space. Nowadays in non-western countries the given tendency is represented by widely-spread industrial, postindustrial, traditional and even archaic enclaves. The enclavisation in Western civilization is closely connected with the immigration flows and great variety of diasporas each of them tends not only to conserve its cultural and confessional identity but to represent it in the sociocultural space of the recipient society also. The surplus heterogeneity can lead to disintegration of recipient culture as well as to deep transformation of its “central” system of symbols and values.
 
The hybridisation can destroy the wholeness of cultural space in a different way producing a number of syncretic cultural forms in which the elements of native and alien cultures mixed in different proportions. On the other hand, hybridisation can be regarded as the “response” to the “challenges” of globalisation, powerful influence of “other” cultures and tendency to unification because it is aimed to adaptation and incorporation of alien cultures phenomena.
  
The analysis shows that the results of hybridization cold be quite dissimilar in long-term perspective in particular. The syncretic cultural forms filled the gap between native and alien cultures can enrich it with new cultural symbols and values. At the same time hybridization can destroy the weakened culture or produce cardinal transformations. The author argues that the consequences depend mostly on the correlation between native and alien in syncretic cultural forms. In modern non-western world for instance the elements of native cultures are prevailed in hybrids whereas in the West the tendency to “appropriate” the other cultures now (under the influence of postnonclassical paradigm and new holistic world-view) is combined with the process of creative adoption of some eastern philosophical and religious views.
