基于应用适宜性评价的太原园林绿化树种选择OA

In order to establish a decision-making process for selecting tree species for landscaping and provide a reference for tree species selection for landscaping in Taiyuan city,in this study,taking the existing 340 landscape tree species in Taiyuan city as the research object,with the goal of evaluating their suitability for application,the Delphi method and the Analytic Hierarchy Process(AHP)were employed to identify 29 foundational indicators reflecting local growth and development conditions,ecological requirements,stress tolerance,pollution resistance,local ornamental characteristics,overall ornamental characteristics,planting costs,and maintenance costs,across three dimensions:ecological adaptability,landscape suitability,and cultivation and maintenance applicability.By establishing a four-level indicator system,the tree species were comprehensively scored.Using the natural breakpoint method,the tree species were divided into four grades based on their scores.Among them,298 tree species were classified as grades Ⅰ-Ⅲ,with overall good suitability,while 42 tree species were classified as grade Ⅳ,with poor suitability and higher restrictions on selection and application.Systematic cluster analysis was conducted on the tree species in grades Ⅰ-Ⅲ,resulting in 15 distinct types with clear characteristics and high discriminative power.Further analysis was conducted to establish a relationship network between the tree species types and their suitability for typical application directions based on the matching degree between tree species type characteristics and selection requirements.In conclusion,it was recommended that the Taiyuan City Landscape and Greening Tree Species Planning should prioritize the selection of the tree species in grade Ⅲ or above,with detailed planning referencing the relationship network for targeted selection.
