丰台区绿堤郊野公园种植结构调整及初步成效分析

Analysis of Planting Structure Adjustment and Preliminary Results of Green Bank Country Park of Fengtai District

绿堤郊野公园作为城市绿地的重要组成部分对宜居城市的营建具有重要作用。改造前,公园原有植物品种单一,植物多样性差;林分以规格种植的片林为主,无明显的层次结构,缺乏自然气息和观赏效果,景观品质较差。现有的绿地水平已不能适应和满足周围居民对环境的需求。因此要调整原有不合理的绿化种植结构,少种草,多栽树,发展节水型绿化。在绿化植物的配置上,要多选择乔灌木,控制草坪的发展;在植物选择上,要适地适树,选择耐旱、节水、涵养水源的植物,积极发展和推广适应性强的乡土树种。公园的改造本着适地适树、景观特色、结构合理三个总原则进行了植物的配置。充分考虑自然植物的共生互补和生物物种的多样性,尽力把乔、灌、花、草结合起来,形成最佳的景观,创造出优美的景观价值,做到春有花、夏有荫、秋有果、冬有绿,三季有花、四季常青;发挥遮荫、降温、除尘等最大生态效能。

Green Bank Country Park, as an important component of urban green space, plays an important role in the construction of livable cities. The plant species were single, plant diversity is poor; stand to specification-based planted woodlots, no hierarchy, lack of natural flavor and viewing the landscape quality is poor before transformation. The status green space and environment cannot meet the level of needs of the surrounding residents. Therefore, we need adjust the original structure of the unreasonable green plants and less grass, more trees, to develop water-saving greening. In the allocation of plants, more choices were on trees and shrubs and control the development of the lawn. In plant selection, native plants and water conservation plants were selected, to actively develop and promote the adaptability of the local tree species. The transformation was conducted with three general principles of suitable tree, landscape features and rational structure of plant configuration, accounting of the natural complementary and symbiotic plant species diversity, try to create a beautiful landscape value with tree, shrub, flower and grass, there is flowers in spring and shade in summer, fruit in fall, green in winter, three quarters of flowering and evergreen; play maximum eco-efficiency of shading, cooling, dusting and others.
