伴随着中国高速公路里程的迅猛延伸和经济的高速发展,资源环境承载能力濒临崩溃,高水平生态绿化需求不断增强。以近几年来对大理至丽江和丽江机场高速公路景观绿化设计等项目为契机,对滇西北高速公路绿化植物应用现状进行统计分析和研究,包括植物物种组成、来源、应用频度、数量,指出目前高速公路绿化植物应用存在以下问题:绿化植物相对短缺、成规模可应用的种类偏少;乡土植物应用比例较低;植物配置手法多样性缺失;绿化苗木储备不太合理。针对滇西北高速公路绿化存在的问题、机遇与挑战,提出见解,以期为未来的发展方向提供指导。
With the rapid expansion of the mileage of China’s expressways and the rapid economic development, the carrying capacity of resources and environment is on the verge of collapse, and the demand for high-level ecological afforestation is constantly increasing. In recent years, taking the opportunity of landscape design of Dali-Lijiang and Lijiang Airport expressways, this paper makes a statistic analysis and research on the application status of afforestation in Northwest Yunnan Freeway, including plant species composition, origin, frequency of application, quantity, There are some problems in the application of greenery in highway: the relative shortage of greenery, the less applied scale of the scale, the lower proportion of native plants, the lack of diversification of plant configuration, and the less reserve of greenery seedlings. Aiming at the existing problems, opportunities and challenges in expressway greening in northwestern Yunnan, the author puts forward some suggestions to provide guidance for the future development.
