文章应用景观生态学原理及3S技术,建立了公路景观评价指标体系及等级划分标准,对武定—昆明公路景观环境现状质量进行了评价。研究结果表明,武定—昆明公路沿线景观类型以农田景观和稀树灌草丛景观为主,其中稀树灌草丛景观与和河流谷地景观的敏感性较高,且两者的阈值较低,公路建设过程中应重点加以保护。综合评价结果表明,武定—昆明公路沿线景观环境现状质量较差,应加强公路内部景观规划设计与外部景观恢复设计,丰富路域内外景观,提高两者的相融性,营造美好的行车环境。
Based on the principles of landscape ecology and 3S technology, this paper established the evaluation index system of highway landscape and the standard of grade classification, and evaluated the status quo of the landscape of Wuding - Kunming Highway. The results show that the landscape types along the Wuding-Kunming Highway are mainly farmland landscapes and thin shrub-grass landscapes. Among them, the landscapes of thin-shelled shrubs and grasslands are more sensitive to the landscape of river valleys, and the thresholds of the two are lower. The construction process should focus on protection. The results of the comprehensive evaluation show that the landscape quality along the Wuding-Kunming Highway is of poor quality, the landscape planning and design of the interior of the highway and the restoration and design of the exterior landscape should be strengthened to enrich the landscape both inside and outside the road, enhance the compatibility between the two and create a beautiful driving environment .
