摘　　要：河岸带是水陆交错带,是河溪的重要组成部分,对人类的生产、生活具有重要的意义。在分析国内外各种对河流评价方法的基础上,结合安达木河水域特点和野外调查,从结构和功能两方面选取了相互匹配的16个指标,采用层次分析和模糊综合评价相结合的方法,构建了河岸带自然性评价指标体系。综合考虑一个平衡河岸带生态系统的特点以及结构和功能等特点,可以将河岸带的近自然程度分为4个等级:自然状态、近自然状态、退化自然状态和退化状态。并以安达木河为例进行评价,评价结果与实际相符合,可作为北京郊区河岸带评价体系。Riparian zone, an ecotone between land and river, is an important component of a river. It is also very significant to human＇s production and livelihood. Based on a variety of domestic and foreign evaluation systems and combined with the water characteristics and field instigation of the Andamu River, 16 indicators are selected for the naturalness evaluation index system that matches both in structure and functions by using the methods of hierarchical analysis and vague integrated appraisal. Under the comprehensive consideration of the geological features and community characteristics of a balanced riparian ecosystem, the near-natural levels of a riparian zone can be classified into four grades, natural state, near-natural state, degrading state, and degraded state. The evaluation results of the Andamu River by using the naturalness evaluation index system match the actual conditions. The naturalness evaluation index system may be applied as a suitable evaluation system for the riparian zones in Beijing sunburn.
