RBPs在苏州河水系生境评价中的应用

Application of RBPs for the habitat assessment of Suzhou Creek

河流生境评价作为河流健康状况评价的重要内容和衡量方法之一,近年来受到越来越多的关注.本文在回顾国外河流生境评价相关理论和实践进展的基础上,引入较具代表性和可操作性的美国快速生物评估协议(RBPs)——生境部分,并尝试以上海苏州河水系为对象开展实证研究.研究结果显示,苏州河水系生境条件受人类活动影响较为强烈,生境质量多处于"较好"～"差"级别;苏州河干、支流生境状况较为接近,上游河流生境优于中下游,农田地区河流生境优于城镇地区;RBPs应用于国内河流生境评价存在一定的适用性问题,但对于发展和完善其评价方法仍具有重要的参考价值.

As an important part of river health evaluations, habitat assessment has received more and more attention. Practice progresses of foreign river habitat assessment are reviewed and the basic thinking with working procedure of habitat assessment in American Rapid Bioas- sessment Protocols （RBPs） is introduced in this paper. Then, an empirical study has been car- ried out on Suzhou Creek in Shanghai. The result indicates that： Suzhou Creek has been strongly affected by human activity, and its habitat quality varies mostly between better to bad levels. Scores of the habitat quality of main streams are close to that of branches, while habitat quality of upstream areas is better than that of lower-middle reaches areas, and rural areas is better than urban areas. Result shows that Rapid Bioassessment Protocols （RBPs） has important referential value to the river habitat assessment in China.
