我国环境水利经过七年多的努力,在水利水电工程环境影响评价、水资源保护等方面取得了可喜的成就,在城市环境水利和流域规划环境影响评价方面亦已开拓出来,这充分说明它有旺盛生命力和社会公认价值。环境水利客观上是一门应用科学。应用科学的一个重要标志是能够用经济价值衡量其利弊和得失。环境水利也不例外。如评价一个水利水电工程对环境影响的方案和水资源保护的目标,都应该有一个公认的价值标准,这样才能具有统一的可比性,这个统一的可比性尺度,对环境水利来说也应该是其 After more than seven years of hard work, China’s environmental water conservancy has made gratifying achievements in the environmental impact assessment of water conservancy and hydropower projects and water resources protection. It has also been pioneered in the environmental impact assessment of urban environmental water conservancy and river basin planning. This fully shows that it has Strong vitality and socially recognized value. Environmental water conservancy objectively is an applied science. An important hallmark of applied science is the ability to measure its pros and cons and pros and cons with economic value. Environmental water conservancy is no exception. Such as assessing the environmental impact of a water conservancy and hydropower project and water conservation goals, should have a recognized value standard, so as to have a uniform comparability. This uniform standard of comparability for environmental water conservancy should also be its
