摘　　要：为实现对河流流域生态状况的高精度综合评价,基于水生生物指标,开展对评价方法的设计研究。从着生藻类和大型底栖无脊椎动物两方面选择水生生物评价指标,完成对生态状况评价指标体系的构建;在遵循“越接近自然状态或受人为活动干扰越小,则该指标得分越高”的原则基础上,对指标标准化处理;将分区作为河流流域基础单位,完成河流流域生态状况三级分区,并结合综合指数法得出综合评价结果。通过对比实验证明,新的评价方法可以实现对河流流域生态状况的高精度、客观评价。To achieve high-precision comprehensive evaluation of the ecological status of river basins,the research on the design of evaluation methods based on aquatic biological indicators is carried out.Select evaluation indicators for aquatic organisms from the perspectives of living algae and macroinvertebrates,and complete the construction of an ecological status evaluation indicator system;standardize the indicator based on the principle of"the closer it is to a natural state or the less it is disturbed by human activities,the higher the score of the indicator";using the zoning as the basic unit of the river basin,complete the three-level zoning of the ecological status of the river basin,and combine it with the comprehensive index method to obtain the comprehensive evaluation results.Through comparative experiments,it has been proven that the new evaluation method can achieve high-precision and objective evaluation of the ecological status of river basins.
