摘　　要：开展系统的河(沟)道监测并实施生态状况分级,是保护河溪沟道等小型水体的重要基础条件。选择北京山区典型沟道(黄峪口沟)开展研究,借鉴欧盟水框架指令,初步建立了包含生物、水文地貌和物理化学三大要素的北京山区河溪生态质量评价体系,并以此为基础开展生态监测工作。研究认为,黄峪口沟道存在轻度至中等程度的人为干扰,生态质量界于"中等"与"好"之间。监测与评价能合理判断河溪沟道的生态现状与存在问题,为有效实施北京山区的水源保护提供科学依据。Monitoring fiver courses （channel） together with classification of its ecological status is vital for the protection of small water bodies of streams or channels. Typical channel of Huangyukou Valley in mountainous area of Beijing is selected for studying. An assessment system of ecological quality of rivers and steams in mountainous area of Beijing is created that include three key factors of biology, hydrogeomorphology and physicochemistry. Ecological monitoring was undertaken which found that artificial disturbance from slight to medium level was existed in Huangyukou Valley and the ecological quality was ranged from medium to good. A rational estimation has been made to the current situation and existed problems through monitoring and assessment which provide a scientific base for effective protection of water sources in mountainous areas of Beijing.
