Research On The Evaluation Of Aromatic Plant Resources And The Construction Of Health Care Landscape In Qionglongshan Forest Park

Suzhou Qionglong Mountain Forest Park has the largest variety of natural secondary forests and rich aromatic plant resources.It is known as Suzhou’s "green lung" and is an excellent tourist destination in Suzhou.This study attempts to systematically study the aromatic plant resources of Qionglongshan Forest Park by means of transect survey,sample plot survey,field research and other methods,combined with literature review.Record statistics.Through literature review,expert questionnaire survey,combined with Delphi method,AHP and fuzzy comprehensive evaluation method,the evaluation index and index weight of aromatic plant resources based on health care function are determined,and a framework model is constructed,and the selected aromatic plants to be tested are substituted into the model.Carry out a comprehensive evaluation of the application of garden health care landscape,and get the evaluation ranking.The main results are as follows:(1)According to the survey statistics: There are 295 species of seed plants in 96 families in Qionglong Mountain Forest Park,including 88 species of trees,54 species of shrubs,128 species of herbs,and 25 species of vines.There are 274 species of aromatic plants in 92 families,including 75 species of aromatic trees,50 species of aromatic shrubs,128 species of aromatic herbs,and 21 species of aromatic vines.There are 206 kinds of aromatic plants with flowers as the main fragrance parts;43 species with leaves as the main fragrance parts;19 kinds with bark branches as the main fragrance parts;fruit as the main fragrance parts 6 kinds.There are various types of plant fragrance in the Forest Park,of which 212 are light fragrance,29 are light fragrance,28 are aromatic,and 5 are strong fragrance.(2)Combined with expert questionnaires,a set of primary selection indicators for the evaluation of aromatic plant resources based on health and health functions was finally formed with aroma,ornamental value,and health care as the criteria.degree,color beauty,plant morphology,viewing cycle,nasal comfort,improve mental vitality,reduce fatigue,reduce tension,feel happy inside,relieve stress,and build an evaluation model.(3)Thirty main aromatic plants,such as Cinnamomum camphora,Pinus thunbergii,Albizia julibrissin,Chimonanthus praecox、Osmanthus fragrans、Exochorda racemose、Loropetalum chinense,were screened out,and were evaluated by the analytic hierarchy process and fuzzy comprehensive evaluation method,and the specific evaluation score was obtained according to the formula.According to the final evaluation results,aromatic plants were divided into grade Ⅲ,grade Ⅰ(>3.6)with high comprehensive value,grade Ⅱ(3.3-3.6)with higher comprehensive value,and grade Ⅲ(3.0-3.3)with average comprehensive value.(4)Finally,combined with the scoring level,corresponding strategies are put forward from three aspects: aromatic plant resource combination construction,space construction,and sensory environment construction.The construction of plant resource combination is to carry out high-frequency collocation of the top aromatic plants,such as Osmanthus fragrans、Chimonanthus praecox、Trachelospermum jasminoides、Thalictrum fortunei、Loropetalum chinense,according to different life forms,fragrance types,and loose fragrance parts;Space creation is to create a health care landscape in Qionglong Mountain from the perspective of scale,level and elements;sensory environment creation is to build a variety of aromatic plants in the health care landscape in Qionglong Mountain Forest Park,according to the health care needs of different groups of people.Model and sensory environment,in order to provide reference for the construction and application of aromatic plants in different health care landscapes.
