This study tried to analyze the impact of climate change on ecological habitat. In this regard, the Rhynchocypris Kumgangensis was selected among the CBIS(Climate-sensitive Biologocal Indicator Species) suggested by the Ministry of Environment. And ecological habitat and restrictive conditions for its survival was surveyed. Future runoff and water quality in the upstream of Pyungchang river were simulated by appling climate change scenarios to SWAT model which is able to simulate water quality. The estimated results explained characteristics on the increase of runoff, BOD, and water temperature and the decrease of DO in the future. The restrictive condition on ecological habitat of the Rhynchocypris Kumgangensis was used water quality during the April to May spawning season since BOD and DO were satisfactory as the first grade of water criteria in the estimated result of future water quality. As a result, it was analyzed that habitat of the Rhynchocypris Kumgangensis in the present was possible about 50~60% of the river. But the habitat would be decreased gradually in the future and would be possible in a very small part of the river in the long term. |
