    摘要:

    为合理精准判别河流生态健康评价等级,应用集对分析原理和五元减法集对势进行河流生态健康评价,并用五元减法集对势判断北运河生态健康发展趋势,识别、诊断影响北运河生态健康的脆弱性指标。结果表明:北运河生态整体处于亚健康状态,为改善北运河生态健康,应优先关注水质指数,在上游河段及时采取措施改善水质,并重视提升和增强全河段的河流连通性和防洪功能;基于减法集对势的河流生态健康评价方法简便、通用性强,评价结果合理,可为河流生态健康评价提供新途径。

    Abstract:

    In order to judge the river ecological health grade reasonably and accurately, the set pair analysis principle and five-variable subtraction set pair potential were applied to river ecological health evaluation, and the five-variable subtraction set pair potential was used to judge the trend of ecological health development of the North Canal and identify and diagnose the vulnerability indicators of river ecological health. The results show that the ecology of the North Canal is in a sub-health state. To improve the ecological health of the North Canal, priority should be given to the water quality index, and the water quality in the upstream should be improved promptly. Meanwhile, it is also important to improve the river connectivity and enhance the flood control function of the whole river section. River ecological health evaluation method based on the subtraction set pair potential is simple and universal, and the evaluation and analysis results are reasonable, which can provide a new idea for river ecological health evaluation.
