河流健康评估1. 采取基于目标的方法来进行评估很重要Importance of objectives-based approach to assessment

2. 需要对指标进行测试来确定是否适宜于当地情况:对照干扰和 /或目标Indicators need to be tested for local relevance: against disturbance and/or objectives

3. 首先,要建立一致的数据采集方法– 质量控制 / 质量保证很重要

In the first instance, establish consistent approach to data collection - importance of quality control/quality assurance

4. 没有必要在所有的站点均使用同样的指标It is not necessary to use the same indicators to compare across sites

Page 23: 2 river health assessment and environmental flows project finding summary

环境流量1. 采取基于目标的方法很重要Importance of objectives-based approach

2. 采取全面的评估方法的价值:与相关概念的科学发展保持一致Value of holistic method of assessment: consistent with concept of scientific development

3. 将方法与当地情况相适应Adapt the method to suit the situation

4. 认识到环境流量是水资源分配过程的核心– 在进行水资源分配时,将相关信息纳入进来,再做出决策

Recognise that e-flows are central to the water allocation process– Make informed decisions when allocating water allocation
