摘　　要：漓江是著名的旅游胜地同时也是泄洪重要河流。为了保护漓江行洪安全并维护自然景观,漓江两岸布设了多种护岸措施。本文结合实地踏查和影像资料,对漓江桂林—阳朔段沿线的护岸措施进行详查,并在汇总各项措施的基础上,对现有护岸型式进行类型划分;然后,选择工程措施-浆砌、工程措施-石笼、植物措施和综合措施作为4种典型护岸措施,并采用定性与定量评价相结合的层次评价法,构建护岸措施功能评价体系;最后,运用护岸措施功能评价体系结合综合评价指数法对4种典型措施的综合功能进行评价。结果表明,植物措施的护岸效果最佳,其次是综合措施,工程措施效果最差,而工程措施中生态型护岸形式石笼明显优于传统护岸形式浆砌。根据评价结果,针对区段不同的安全要求提出了最佳的护岸措施及方案,并建议适当提高植物措施和综合措施在漓江护岸工程中的比例,既保证岸坡稳定,又改善岸坡生态环境。The Lijiang River is a famous tourist resort in the Guangxi Zhuang Autonomous Region of China, as well as a major river for flood discharge. To ensure the navigation safety and protect the natural landscape of the Lijiang River, different types of revetments have been established along the Lijiang River since the end of 1980s, including engineering measure, plant measure and comprehensive measure. However, the status quo and effect of these revetments remain unclear, and there are few researches on functional assessment of riparian revetments. Given this situation, we carried out field investigation of revetments and established a functional assessment system on revetments in this study, in order to lay foundation on functional assessment on riparian revetments and provide theoretical basis and guidance for the construction and management of revetment restoration projects along the Lijiang River. In this research, the status of existing revetments along the Guilin-Yangshuo section of the Lijiang River was surveyed and classified systematically after thorough field investigation combined with image data. Then, engineering measure-masonry, engineering measure-gabion, plant measure and comprehensive measure, were selected as four representative revetment measures. After that, a functional assessment system on revetments was established using analytic hierarchy process which combined qualitative and quantitative assessment. The final result of functional assessment on these four representative revetments was demonstrated in the comprehensive evaluation index. The assessment results showed that plant measure worked best, followed by comprehensive measure, engineering measure-gabion and, in the last place, engineering measure-masonry. Comparing two engineering measures, the gabion, which is more ecological, worked much better than the masonry. According to the above assessment result, and considering different safety requirements in different river sections, the optimal revetment measure and the ideal restoration propo
