广州白云山风景区园林边坡地被植物调查评价

Investigation and Evaluation of Landscape Slope Ground Cover Plants in Baiyun Mountain Scenic Area,Guangzhou

植物作为预防水土流失的首要手段,在园林边坡的应用中发挥着重要作用。对白云山风景区的33个园林边坡的地被植物进行调查评价,运用层次分析法,构建以生态性、适应性及观赏价值3个准则层及10个指标因子的评价模型,对边坡地被植物进行筛选评价。结果表明,应用频率较高的18种边坡地被植物可分为3个等级,其中Ⅰ级有3种,Ⅱ级有11种,Ⅲ级有4种,鹅掌藤Heptapleurum arboricola、红花檵木Loropetalum chinense var.rubrum、假连翘Durantaerecta等是边坡植物材料的优良选择。最后提出优先考虑植物的护坡能力,提高乡土植物比例,丰富植物层次等坡地植物配置建议。

As the primary means of preventing soil erosion,plants play an important role in the application of garden slopes.In this paper,the ground cover plants of 33 garden slopes in Baiyun Mountain Scenic Area are investigated and evaluated.Using the analytic hierarchy process(AHP),an evaluation model based on 3 criteria layer factors of ecological,adaptability and ornamental value and 10 index factors is constructed to screen and evaluate the ground cover plants on the slopes.The results show that 18 kinds of slope ground cover plants with high application frequency can be divided into 3 grades,including 3 species of Grade I,11 species of Grade II,and 4 species of Grade III.Heptapleurum arboricola,Loropetalum chinense var.rubrum,and Duranta erecta are good choices for slope plant materials.Finally,it is suggested to prioritize the slope protection ability of plants,increase the proportion of local plants,enrich the plant hierarchy in slope plant configuration and so on.
