摘要
采用系统取样法和典型样地法对自贡市建成区范围内25条典型道路(快速路、主干道、次干道)的绿化植物配置模式进行调查分析,并运用综合评价指数法建立综合评价体系,对自贡市道路绿化现状进行分级和评价.结果表明:①自贡市道路绿化整体效果较好,调查的25条道路中,道路绿化水平达到Ⅰ级(优秀)和Ⅱ级(良好)的道路占比68%;②不同道路之间绿化水平差距较大,各等级道路整体绿化水平由高到低依次为主干道、快速路、次干道;③根据城市道路现状及其绿化需求,以及各评价分析结果提出适当增加植物种类、丰富道路绿化植物层次结构、利用不同的景观空间营造方法对植物进行配置、提高观赏性植物应用比例、注重植物种植规划和整形修剪以及提高养护管理水平,强调植物与周围环境协调性等针对性建议.同时提出各级次道路的植物配置优化方案,以期未来为其他城市道路绿化建设提供一定的参考.
The methods of systematic sampling and typical sample plot were used to investigate and analyze the allocation mode of green plants of 25 typical roads within the urban area of Zigong City,and the comprehensive evaluation index method was used to establish a comprehensive evaluation system to classify and evaluate the current status of road greening in this city.The results showed that the overall status of road greening in Zigong City was relatively good,and that the greening level of the roads was of GradeⅠ(excellent)or GradeⅡ(good),accounting for 68%of the total.The difference of greening level between different roads is large.The overall greening level of each grade road from high to low is main road,expressway,secondary road.According to the current status of urban roads of Zigong and their greening needs,and based on the results of evaluation and analysis,some targeted suggestions were put forward,such as appropriately increasing plant species,enriching the hierarchical structure of road greening plants,using different landscape space construction methods to configure plants,increasing the application proportion of ornamental plants,paying attention to the planning and shaping of plants,improving the level of maintenance management and emphasizing the coordination between plants and surrounding environment.Finally,a plant configuration optimization model for each type of roads is proposed,with a view to providing reference for the construction of other urban roads in the future.
