基于“植物功能性状-生态系统服务”评价框架的园林树种选择方法

摘要:绿化植物对城市绿色空间的服务作用,对整个城市绿色空间的健康与稳定性有着重要的作用。然而,长期以来,人们对植物的选材机理与方法缺乏科学的指导,且存在一定的主观随意。本研究以上海50个主要绿化树种为研究对象,以其为研究对象,对其进行了17项特征因素的因素分析,并对其进行了初步探讨,结果表明二者具有相关关系。从形貌上看,林木高度是影响林木生长的重要因素,并对微气候调节、径流调节、空气净化、降噪等生态调控功能发挥着重要作用。植物的叶特征直接影响着植物的固碳释氧和营养供应,进而反馈于植物的种间功能。树木的文化功能与人们的选择有着密切的关系,其多样性和独特性决定了树木的文化功能必须在现实生活中作出折衷选择。本项目提出的"植被特征-生态系统服务"评估模型,可为绿化物种的合理选用和合理配置提供科学的理论基础,从而为城市绿化的整体效果量化和最佳化奠定基础。

Selection method of garden tree species based on the evaluation fr amework of "Plant functional characters-ecosystem services"


Abstract: The service function of garden trees directly affects the health and stability of urban green space system and urban ecosystem. However, over the years, the selection mechanism and method of garden tree species lack of theoretical support, which is often subjective and arbitrary. Through the establishment of the evaluation fr amework of "plant functional characters-ecosystem services" of 50 garden tree species in Shanghai and the analysis of 17 character variables, it was found that there was a certain correlation between tree functional traits and ecosystem services. In terms of morphology, tree height determines tree shape and crown size, and contributes to microclimate regulation, runoff regulation and storage, air purification, noise reduction and other regulatory services to varying degrees. Leaf traits affect ecosystem processes such as carbon sequestration, oxygen release, and nutrient supply, and ultimately feed back into service differences among tree species. The cultural service of tree species is directly related to human preference, which has complexity and particularity, and needs to be balanced according to actual needs. The evaluation fr amework of "plant functional characters-ecosystem services" provides an ob jective and rational method for the selection of garden tree species and tree species planning, which is convenient to provide the corresponding tree species selection basis for different ecosystem services, so as to realize the quantification and optimization of the comprehensive benefits of urban green space.
