高速公路护坡景观可持续性综合评价

Comprehensive Evaluation on Landscape Sustainability of Highway Slope

针对我国高速公路护坡景观综合效益研究滞后于高速公路建设,制约高速公路生态可持续建设和发展,造成高速公路护坡生态破坏,景观退化,养护与管理成本过高等问题。对河南省郑—卢高速公路护坡景观的施工类型进行调查,采用层次分析法(AHP)和模糊综合评价对高速公路景观生态可持续性进行评价。结果显示:1郑—卢高速护坡综合评价等级总体偏低;2生态效益在综合评价中所占比重最大,是护坡景观构建的关键;3护坡景观模式生态效益CEI综合评价中分级挂网喷播优于其他类型。

The highway side slope comprehensive benefits research in China lags behind the highway construction, which restricted the highway construction and development of ecological sustainability. It brings the problems such as the ecological damage, landscape degeneration, and high cost of maintenance and management of the highway slope protection. In this paper, we evaluate highway landscape ecological sustainability by the AHP and fuzzy comprehensive evaluation method. The results showed that： （1）Zheng-Lu highway slope landscape model of ecological adaptability low level which needs to improve. （2）Ecological benefit in the comprehensive evaluation of proportion is the largest, and is the key to slope protection landscape construction ;（3）CEI landscape model of ecological slope protection benefit comprehensive evaluation according to grading net-suspended spray seeding is better than other types.
