Abstract

The Razim-Sinoie lake complex is situated in northeastern Dobrogea, south of the Danube Delta and on the coast of the Black Sea (44°47’ and 45°01’ northern latitude and 28º30’ and 29°08’ eastern longitude), constituting the largest water surface in our country. It appeared and evolved in a former branched marine gulf, Halmyris, at the basis of a fossilized marine cliff (in the west), being connected to Sfântu Gheorghe branch (in the north) by means of several canals and backwaters and separated from the sea by several alignments of low and weakly consolidated marine bank-ridges, all these characteristics conferring it numerous particularities reflected in the hydrological, thermo, dynamical and hydrochemical regime of the lakes’ water. The great diversity of the aquatic ecosystems and their accentuated vulnerability in relation to the anthropic intervention requires that their management and their economic valorization must have as a major desideratum the conservation and the protection of the biodiversity, in order to obtain an ecological balance. In order to attain these desiderata, by means of the Law no. 82 of November 20, 1993/ HG no. 248 of May 27, 1994 concerning the creation of the “Danube Delta” Biosphere Reserve, three types of areas were established within it, namely: strictly-protected areas (with integral protection), namely 18 (50600 ha, out of which in the Razim-Sinoie complex, 6 such areas add up to a total surface of 9123 ha), buffer-zones (223300 ha) and economic zones (306100 ha) where people currently practice traditional economic activities and which include all the rural and urban localities (Sulina)
