Abstract: In China, the Karst water areas and the highest hydropower potential areas are overlapped, which mainly located at the Southwestern regions. In these areas, the Karst water areas have unique geological conditions and fragile environment and are largely affected by dam construction. The cutting-edge perspectives on Karst water environment include dam construction effects, water environment management strategy and aquatic species ecological assessment. The objective of this paper was to assess the dam construction effects and ecological status of Karst areas in the Kraal River basin, Guizhou Province, China. Factors affecting dam construction in karst areas are investigated. The ecohydraulic model system was used to assess the ecological impacts in downstream of Kraal River. The information from this study can be used for water environmental regulation and possible policy development in karst areas.
