伦潭水电工程建设对生态容量的影响研究

水电工程的建设对水库上下游的生态环境容量将产生影响,其影响大小是水电站建设经济性评价的一项重要内容。在江西省伦潭水电工程生态影响分析中,利用生态足迹法对工程建设前后水库影响区的生态环境容量变化进行了分析。分析结果表明:伦潭水电站建设对库区耕地的淹没将减少生态环境容量,但由于发电效益、水库库区渔业生产能力及水库灌溉能力的增加,又将增加生态环境容量。主要表现在灌区和下游保护区耕地的单位生态生产力提高等方面,说明水库下游和灌区为水库兴建的受益者,应对库区移民进行生态补偿。

Impact of hydropower project construction on ecological carrying capacity

The construction of hydropower project will exert an impact on the ecological carrying capacity in the upstream and downstream of the reservoir,which is an important index of its economic assessment.In the construction of Luntan Hydropower Station,the ecological environment capacities before and after construction in the reservoir-affected area are analyzed by ecological footprint method.The analysis results show that the construction of Luntan Hydropower Station will reduce ecological carrying capacity for...
