【摘要】：本文以濮阳市清丰县政通大道为研究对象,对道路周边植物的种植状况、配植模式、美观三方面进行研究,并为其优化升级改造提供科学依据。研究采取实地调查和典型取样的方法,调查了政通大道周边观赏植物的种类,选取3个典型景观节点,着重对其道路两侧的植物种类构成、数量、面积、本地植物资源选择的应用状况、营造的景观效果、乔灌草的配植特点、植物种植形式等进行研究,同时对典型景观节点的植物配植进行评价,分析政通大道植物应用方面存在的问题,探讨解决问题的相应对策。其研究结果如下:(1)对政通大道的景观空间层次关系、尺度与位置关系、比例关系、与周边衔接、主环道行道树、草坪、骨架性乔木、低层灌木与地被植物的组合及设置、景观维护和照明设计11个要素分3个等级层面进行定性和定量分析,并采用层次分析法进行综合评价,得出:政通大道的景观植物应用状况与效果最终得分为6.7分。这说明政通大道在道路植物的配植方面,整体质量尚可,但是应相应增加行道树种类、宿根花卉、乔灌草的种植数量。(2)就植物配植方面而言,政通大道共有乔灌木42种,其中乔木26种,灌木16种;有3种为常绿乔木,其余均为落叶植物。在应用的42种植物中,属于乡土植物的种类为30种,占市区道路树木种类总数的90%,达到了清丰县生态城市建设要求的“乡土树木占树木总数70%”的标准,但在常绿树种、多年生花卉植物的种类与数量方面稍显不足,应增加这两类植物的种类与数量。(3)“三分种植,七分养护”,植物的养护情况直接关系着所呈现出的观赏效果,政通大道在植物的养护方面存在着管理粗放、人为践踏、修剪不及时等问题,有待提高。
[Abstract]:Taking Zhengtong Avenue of Qingfeng County in Puyang City as the research object, this paper studies the planting condition, planting pattern and aesthetic appearance of plants around the road, and provides scientific basis for its optimization and upgrading. By using the method of field investigation and typical sampling, the species of ornamental plants around Zhengtong Avenue were investigated, and three typical landscape nodes were selected. The composition, quantity and area of plants on both sides of the road were emphasized. The application of local plant resource selection, the landscape effect, the planting characteristics of Arbor and shrub grass, the plant planting form and so on were studied. At the same time, the plant matching of typical landscape node was evaluated. The problems existing in plant application in Zhengtong Avenue are analyzed, and the corresponding countermeasures to solve the problems are discussed. The results are as follows: (1) the relationship of landscape spatial level, scale and location, scale and position, proportion, connection with surrounding, main ring road, lawn, skeleton tree, lower layer shrub and ground cover plant combination and setting, are studied as follows: (1) the relationship of landscape spatial level, scale and position, proportion relation, connection with periphery, main ring road, lawn, skeleton tree, lower layer shrub and ground cover plant, The 11 elements of landscape maintenance and lighting design were qualitatively and quantitatively analyzed in three levels, and the comprehensive evaluation was carried out by AHP. It was concluded that the application status and effect of landscape plants in Zhengtong Avenue were 6.7 points. This shows that the overall quality of the road plants in Zhengtong Avenue is fairly good, but it is necessary to increase the number of street trees, perennial flowers, trees and shrubs. (2) in terms of plant matching, there are 42 species of trees and shrubs on Zhengtong Avenue. Among them, 26 species are trees, 16 species are shrubs, 3 species are evergreen trees, and the rest are deciduous plants. Among the 42 kinds of plants used, 30 species belong to local plants, accounting for 90% of the total number of trees on the road in urban areas, which meets the standard of "local trees account for 70% of the total number of trees" as required by ecological city construction in Qingfeng County, but in evergreen trees. The species and quantity of perennial floral plants are slightly insufficient, and the species and quantity of these two kinds of plants should be increased. (3) "Three-point cultivation, seven minutes conservation", the conservation situation of plants is directly related to the ornamental effect. There are some problems such as extensive management, human trampling and untimely pruning in the maintenance of plants in Zhengtong Avenue, which need to be improved.
