| 摘 要： | 以深圳市的3条河流为实例,对河流生态系统健康理论和评价方法进行了研究。建立了以水化学和水生物指标为基础的河流生态系统健康评价指标体系,并确定评价指标的等级标准。提出了基于模糊概率的河流生态系统健康评价方法,以反映河流健康状况以及不同健康状况河段所占的比例。结果表明,深圳河流有70%以上河段处于亚病态和病态状态,仅有45%的河段达到健康水平,说明受到人类活动影响严重,河流生态系统严重退化。

| Abstract: | Taking three rivers in Shenzhen City as cases,the theory and assessment method of river ecosystem health were studied.An indicator system of river health was developed based on the chemical and biological indicators,and its evaluation standards were classified.An evaluation method based on fuzzy-probability synthetic method was established for the evaluation of the healthy status and the determination of proportion of rivers with different healthy status.The results indicate that about 70% of the rivers are of sub-illness or illness,and only 45% of them are healthy,which mean that these river ecosystems have seriously degraded. |
