4 river health assessment liao river pilot-cand_e

  1. 1. 太子河河流健康评估 汇报人:渠晓东 中国环境科学研究院 CRAES
  2. 2. Lecture scheduleThe theories and methods of the stream health assessment河流健康评估的理念与方法;The stream health assessment – Taizi River and Liao River Pilot study河流健康评估方法-太子河实例研究
  3. 3. 河流健康评估的理念与方法
  4. 4. The river health  用 ‚健康‛一词来反映河流的状况,是一个很形象的 比喻,容易被公众接收和认识,并能得到广泛的关注 (Boulton, 1999)。  对河流来讲,健康-即‚保持好的状态‛,其来源于 人的健康,但与人的健康概念并不相同(Karr 1999)。  What is river health?  ‚维持水体的物理、化学和生物的完整性-具有自身 的组织(self-organization),具有生产力 (productive)和抗性(resilient) (Karr and Chu, 1999)。
  5. 5. The methods for river health assessment  传统方法使用单一化学、物理或者生物评价河流的水 质(如我国的水质监测系统),其或多或少的反映了 河流健康的某一部分,并取得了一定的评价结果,但 往往很难应用于大尺度的流域管理(Norris & Thoms, 1999)。  利用多参数(multimetrics)或者多变量 (multivariates)的方法开展的一系列的河流健康评价 (Karr 1999;Norris and Hawkins, 2000)。  基于生物完整性思想,提出评估河流的物理、化学和 生物完整性,构建综合评价因子;强调河流生态系统 的完整性,评价结果与社会、经济和流域管理建立联 系,研究与管理密切联系(Bunn et al., 2010)。
  6. 6. 综合评价法思路示意图 Yes No 指示因子是否对干扰 具有响应 No No yes yes
  7. 7. 太子河河流健康评估
  8. 8. 河流的分区和分类 DEM, A-R相似的河流类型和河流级别
  9. 9. 识别主要环境问题 生活污染 工业污染挖沙活动 The main disturbances in the Taizi River
  10. 10. 开展河流监测-指示因子的筛选 Everyone has their own ‘pet’ indicators 每个人都会采用自己喜欢的指示 方法

  13. 13. Table 1. The part of fish indicators for stream health assessment
  14. 14. Table 2. The part of macroinvertebrates indicators for stream health assessmentSensitive speciesTolerant species
  15. 15. Selection of indicators-重要的是,选择能敏感、稳定反映人为活动压力的因子 Important to select a few indicators that are meaningful. 选择有意义的指标非常重要 •Ones that respond to things that threaten the values we identify 这 些指标可以直接响应我们确定的河流既定价值 •Guide management actions 为实施管理提供指导方针 Design of the monitoring program and selection of indicators are very important. 监测项目的设计及评估指标的选择非常重要
  16. 16. 指标的类型多样 Water quality indicators  Dissolved oxygen, conductivity, pH, turbidity, nutrients, anions and cations, heavy metals Biological pattern indicators  Fish Assemblage Composition  Various indicators using richness, abundance, presence/absence of species  Macroinvertebrate Assemblage Composition  Various indicators (e.g. richness) and predictive models (e.g. observed vs. expected) Process and biological function indicators  Primary production, benthic metabolism and nutrient cycling, decomposition, fish body condition, food webs
  17. 17. 指标应用前的测试是必须的Literature survey – examplesfrom previous studies 文献综述——文献研究中的案例Disturbance gradient approachto detecting impacts应用干扰变化方法发现影响• Define a disturbance gradient 定义干扰变化• Objective comparisons - at same sites & times 目标比较-在相同试点和时间
  18. 18. Ecological health indicator生态健康参数指标 Reference values 参数值 Low低 High高 Disturbance gradient 干扰变化
  19. 19. 参数的响应干扰强度
  20. 20. 太子河河流健康评估中使用的EPT指数Table1. Conversion of EPT richness ratio (family) (EPTr) to benthicmacroinvertebrate river health sub-indicator score, according tocatchment zone. EPTr range [1] River health EPTr river health sub- class indicator score Mountain and Alpine Midland and Lowland ≥ 0.45 ≥ 0.34 1.0 1.0 0.42 – < 0.45 0.31 – < 0.34 0.6 – < 0.8 0.7 0.36 – < 0.42 0.26 – < 0.31 0.4 – < 0.6 0.5 0.26 – < 0.36 0.18 – < 0.26 0.2 – < 0.4 0.3 0.00 – < 0.26 0.0 – < 0.18 0.0 0.0 Based on data in Lenat, D. 1988.

Technical Regulation for Assessmentof River Health1) We regulated the main aspects for assessing the river hea 2) It includes the hydrology (developed hydrological assessing model), physical form (longitudinal and transverse disturbances, bed disturbances, and sediment transport), water quality (nutrients and quality), fish, benthic macroinvertebrates, algae (community level and biological indices) and riverine vegetation;3) The data collection and analysis would follow theregulated process;4) The reference condition for each indicator are couldbe cited from the published papers or reports;5) Combined scores to reflect the health condition of
  25. 25. What we have learnt 管理提高 1) 通过项目的参与,提高了对河流健康评价的理解和认 识,提升了河流健康评价的方法;提升了地方政府对河流 健康的认识和认可,为河流的生态管理奠定基础; 技术突破 2)在中澳专家的共同合作下,提出了《河流健康评价技术 规范》(征求意见稿),为我国的河流生态系统评价与管 理,提供了重要的技术手段; 在研究中,首次利用多种化 学、物理和生物指数构建评价体系,通过与澳方专家的合 作,构建了太子河评价指标体系,参照体系和评价方法; 方法突破3) 利用河流健康报告卡,为河流管理者和公众提供便捷的途径了解河流的健康状况,开展河流的保护。
