河流生态系统作为人类生活生产的重要支持系统，保持河流的自然性具有重要意义。本文结合湟水河西宁段高原半干旱区河流的特点，选取26个定性、定量指标组成的高原半干旱区河流自然性评价体系，运用层次分析法（AHP）确定各指标权重，从地貌特征、生态特征、水文特征、社会服务功能四个方面对湟水河综合自然状况进行评价。结果表明，评价河段中28％的河段处于近自然状态，39％的河段处于退化自然状态，33％的河段处于人工状态，湟水河西宁段总体处于退化自然状态。此外，在验证结果中多目标线性加权函数法与灰色关联分析结果基本一致。所建立的河流综合自然评价指标体系可应用于其他高原半干旱区河流的自然性评价，为后续河流生态修复和保护工作提供依据。

Based on the characteristics of Huangshui River ,a semi-arid plateau region river naturalness assessment system is estab-lished ,including 26 qualitative and quantitative indicators .Weight of each indicator is determined with Analytic Hierarchy Process (AHP) and the assessment is from four aspects including geographic features ,ecological features ,hydrological features and social services .The results show that in the assessment section 28% is in near-natural state ,39% in degenerate state ,and 33% in artificial state .On the whole ,the Xining section of Huangshui River is in degenerate state .Besides ,the assessment results with multi-objec-tive linear weighting function method and gray relational analysis are similar .The comprehensive naturalness assessment system es-tablished in this paper can be applied to other semi-arid plateau region rivers'assessment and can provide a basis for follow-up river e-cosystem restoration and protection .
