Conclusions 总结(1)• Many different policy decisions relating to:许多不同政策制定均与以 下各因素相关: – What is an acceptable level of health 河流健康的可接受底线 – How information should be presented 信息的表现方式 – Suitability of different methods and indicators 各种不同方法及 评估指标的适用性• Suitability will depend on: 这些适用性主要由以下各因素决定: – Objectives 目标 – Resources 资源 – Capacity 能力
  38. 38. Conclusions 总结(2)• Importance of making informed decisions知情决策的重要性 – Awareness of what is important in the river找出哪些对于河流是 至关重要的 – Understanding the flow requirements of the ecosystem 掌握生态系统对水流的要求 – Understanding the health of our river system认识河流系统的健 康 – Conscious decisions about what is acceptable and what is not; and what we will do about it 确定哪些是可以接受的,哪些不可以接受,以及为此该如何做
