在流域综合治水概念取代早先单目标管理概念的 70多年里 ,为了实现综合治水方略的整体目标———既要兼顾社会与环境系统 ,又要走可持续发展之路 ,国际上很多科研与决策机构都面临着日益增多的问题 .实践表明 ,治水措施的范围迫切需要继续扩展 ,并作为评估过程的一部分来考虑 ;评价各项措施的标准也急待深入研究 ,以协调不同的评估准则 ;尖锐的、恰当的后评估工作急需开展 ,以把握治水措施带来的实际后果 .这也提示我们 ,真要充分发挥综合治水的全部潜能 ,仍会是路漫遥遥 .改进分析方法与必要的体制改革所面对的问题都是十分艰难的
In the more than 70 years in which the concept of comprehensive water management for watershed replaced the previous concept of single-objective management, in order to achieve the overall goal of a comprehensive water control strategy, it is necessary to take both social and environmental systems into consideration while pursuing the path of sustainable development. Many international research and decision-making Agencies are facing an increasing number of problems. Practice shows that the scope of water control measures urgently needs to be further expanded and considered as part of the assessment process. Criteria for assessing various measures are also urgently needed to study in depth to harmonize different assessment criteria. Sharp The proper post-assessment work is urgently needed to grasp the actual consequences of water treatment measures, which also prompts us that we must still give full scope to the full potential of comprehensive water control and still have a long way to go. Improving Analytical Methods and the Necessary System Reform The problems we face are very difficult
