摘要:

河湖健康评价对于保障水资源安全、促进可持续发展具有重要意义。采用改进CRITIC-熵权法组合赋权模型,计算了高原河湖健康评价体系的指标权重,并对尼洋河和扎日南木错进行了评价。评价结果显示,尼洋河的健康等级为“健康”,准则层权重大小依次为社会服务功能、“盆”、“水”、生物;扎日南木错的健康等级为“非常健康”,准则层权重排序为“水”、“盆”、生物、社会服务功能;评价结果表明,尼洋河的河岸带植被宽度、岸线稳定性较低,扎日南木错则在岸线自然状况、大型底栖动物生物完整性和湖泊营养状态等方面仍需改进;最后,河湖对尼洋河和扎日南木错的保护和管理提出若干建议。

Abstract:

Assessing the health of rivers and lakes is crucial for ensuring water security and promoting sustainable development. Building upon previous research, this study employs an enhanced CRITIC-entropy weight method to calculate the index weights within a health assessment system for plateau rivers and lakes. Evaluations were conducted on the Nyang River and Zari Namco Lake, revealing the former’s health status as “healthy” with criterion layer weights assigned to social service function, “basin”, “water”, and biology in descending order. Zari Namco achieved a “very healthy” status, with criterion layer weights ordered as “water”, “basin”, biology, and social service function. The findings indicate a need for improvement in the Nyang River’s riparian vegetation width and shoreline stability, while Zari Namco requires enhancements in shoreline natural conditions, macrobenthic organism integrity, and lake trophic status. The paper concludes with several recommendations for the protection and management of both the Nyang River and Zari Namco Lake.

Key words: health assessment, combinatorial weighting method, improved CRITIC-entropy method, Xizang, Nyang River, Zari Namco Lake
