Abstract

Nowadays natural habitats are imperilled because of human landscape-transformer processes and negative effects of climate change. Watery habitats belong to the most vulnerable lands because low rate of anthropogenic effects can lead to significant and fast changes in these places. Although we can characterize Carpatian Basin with high mosaicity, it is need to be managed in its entirety without borders. The international realization of this is supported by the Hungary-Romania Cross-Border Co-operation Programme of the European Union. Conditions of Püspökfürdő (karst lake with thermal spring-water, Pârâul Peţea reserve, Oradea, NW Romania) and anthropogenic effects in dynamics of environmental processes are examined in this project. Paleoecological analysis, soil- and wather-chemical measurements and geological examinations are carried out in the area. Based on laboratory measurements and field studies we are able to do comparative analysis, prepare parameter-maps and examine the evolution of the area. Aims of our work are to classify ecological potential, to define the rate of degradation and to determine ecological function of the natural habitat. Results give possibility to sustainable development of tourism investments and operation in case of Püspökfürdő, what assists the improvement of ecological status of the lake, because Pârâul Peţea reserve is touched by anthropogenic effects in higher degree. In this paper we present a part of examinations of water chemistry.
