上海郊野公园河岸带景观乔木树种选择与评价

Selection and Evaluation of Ornamental Tree Species for Riparian Landscape of Country Park in Shanghai

河流廊道是平原河网地区郊野公园的重要部分,连接着田和林等重要生态基底。基于上海郊野公园的建设目的,通过调查评价滨水立地条件下河岸带景观乔木树种的生长适应性、生态防护性和景观美学性,采用层次分析法和聚类分析法将54种乔木树种划分为适应能力、防护效果和观赏价值不等的强、中、差3类,以满足河岸带不同种植环境的植物选择和配置需求,优选出适应性强、防风能力强、观赏价值较高的树种15种。研究结果可为今后郊野公园景观设计提供借鉴。

River corridor is an important part of the country parks in the plain river network area,which connects the important ecological matrix such as farmland and forests.Based on the development purpose and demand of country parks in Shanghai,the growth adaptability,ecological effect and ornamental aesthetics of the tree species for riparian zone are investigated and evaluated.The analytic hierarchy process and cluster analysis are adopted to divide 54 tree species into three categories of strong,standard and weak for growth adaptability,ecological effect and ornamental value,so as to meet the needs of different planting environments in riparian zones for plant selection and configuration.Fifteen species with strong adaptability,strong wind resistance and high ornamental value are selected for recommendation.The research would provide reference for the landscape design of country parks in the future.
