北京郊野地区园林地被植物综合评价与分级

北京郊野地区常常出现风大扬尘、土壤沙化、风力侵蚀等现象，高大乔木生长常受抑制，因此地被植物的应用对改善生态、提升人居环境质量等方面起到了至关重要的作用。在对北京市永定河莲石湖景区、八家郊野公园、玉东郊野公园、奥林匹克森林公园、野鸭湖湿地、颐和园6个地点的地被植物的种类、生长状况及景观效果进行调查的基础上，建立了地被植物园林应用的评价体系。从生长特性、观赏特性、适应特性3方面利用层次分析法进行综合评价与分级，共筛选出了31种适用于北京郊野地区园林绿化的地被植物，为未来北京郊野地区公园建设提供参考。

Comprehensive Evaluation and Selection of Ground Cover Plants in Countryside of Beijing

For the strong wind, sandstorm, desertification and wind erosion, the growth of the arbors is restrained and the ground cover plants are essential for improving ecology and promoting human settlements. Based on the investigation about the species, growth status and landscape effect of the existing ground cover plants in the Lotus Stone Lake area, Bajia Country Park, Yudong Country Park, Olympic Forest Park, Yeyahu Wetland and the Summer Palace, a comprehensive evaluation system of ground cover plants was established from three aspects: ornamental characteristics, growth characteristics and adaptation properties by using the analytical hierarchy process, 31 kinds of Beijing landscape groundcover plants were elected for the landscape application in countryside of Beijing finally. It’s expected to provide certain theoretical basis and reference suggestion about the country park construction in Beijing.
