摘 要:以黑龙江上中游为例,研究国际界河的河流健康评价。为了全面衡量该过程中的随机性与模糊性,将云模型引入河流健康评价。基于水文特征、形态特征、水体特征等7个层面选取了16个指标构建了黑龙江上中游河流健康评价指标体系,以2013年为典型年对其进行了河流健康评价。结果表明:黑龙江上中游2013年河流健康等级为"中"。分析了影响河流健康的主要因素,并针对性地提出了一系列河流治理措施:加强水污染控制、加固沿岸堤坝、退耕还林恢复湿地、实施生态调度等。Using the upper and middle reaches of the Heilongjiang River as an example, we assessed the health status of international boundary rivers in this study. In order to comprehensively analyze the randomness and fuzziness during the assessment, we introduced the cloud model into the study and constructed a river health assessment system for the upper and middle reaches of the Heilongjiang River. The criterion layer of the system contained seven factors, including river hydrology, river morphology, and characteristics of water, and the index layer of the system contained 16 indices. The system was used to assess the river health in the typical year of 2013. The results show that the river health was at the middle level in 2013. We also analyzed the main factors that affected the river health and put forward a series of measures for river management improvement, including enhancement of water pollution control,reinforcement of dams along the river bank, reforestation of cultivated land and restoration of wetlands, and implementation of ecological operation.
