Under the background of taking ecological priority as the high-quality development strategy of Guizhou,the unique plant landscape created by wild native Lithophyte can make contributions to ecological construction.This article is based on the concept of near natural landscape architecture and applies the Analytic Hierarchy Process to construct a plant evaluation index system for Yunmanhu Rock Garden in Gui’an New Area.Combining domestic and foreign rock garden analysis to extract the plant landscaping mode of rock gardens,a plant landscaping strategy for rock gardens is formulated in practical cases,which is of significance for constructing a reasonable and complete plant landscape evaluation system for Guizhou Rock Garden and enriching the types of gardens in China.The main conclusions of the paper are as follows:(1)Visualize and summarize the current research status of rock gardens both domestically and internationally;By drawing flat and vertical views of different spaces in different rock gardens both domestically and internationally,the characteristics of the plant landscape composition in rock gardens are analyzed.The plant landscape models in rock gardens are divided into three categories: foreign,provincial,and domestic,and explained from different rock types;The summarized principles,design concepts,and key points of rock garden plant landscaping provide support for subsequent research.(2)Based on the concept of near natural garden,304 plants selected through Natural selection were sorted out from 1077 plants as the basic data for screening;Using the AHP method,a plant screening and evaluation system for Guizhou Rock Garden was constructed around 5aspects,including 26 evaluation indicators;And a comprehensive evaluation and grading were conducted,and the top 30 plants with comprehensive scores were selected as recommended plants based on their lifestyle.(3)Using the previous research results,we will focus on using wild local plants to enhance and transform the plant landscaping of Yunman Lake Rock Garden,in order to create a sustainable ornamental rock garden;attempt Using philosophical stories to connect and plan three spaces;Find appropriate expressions for creating plant imagery in plant landscaping;In the process of improving the plan,plant landscaping strategies were proposed for the leading space,core space,and subsequent space of the Rock Garden.
