| This research uses comprehensive horticultural therapy,aromatherapy,environmental psychology and environmental behavior to study the basic theories related to healing gardens.The main research objects are the outdoor landscapes of general hospitals,specialist hospitals,and sanatoriums,and 8 cities in Changsha are selected.Representative hospitals conduct on-site plant landscape surveys;at the same time,AHP and POE post-use evaluation methods are used to evaluate plant landscapes on the site.The main findings are as follows:1.According to the investigation from the direction of plant species composition characteristics,it is found that Xiangya Hospital of Central South University has 22 departments and 30 species of plants;Xiangya Second Hospital has 18 departments and 23 species of plants;Xiangya Third Hospital has 22 departments and 25 species of plants;Changsha Central Hospital has 33 departments and 44 species of plants;Provincial Children’s Hospital has 27 departments and 38 species of plants;Provincial Tumor Hospital has 22 departments and 31 species of plants;Carnation Sanatorium has 22 families and 39 species of plants;Mawangdui Sanatorium has plants 29 families,38 species.Secondly,it analyzes the plant species in the site from five perspectives: vision,hearing,smell,taste,and touch.2.Based on the characteristics of plant space composition,the horizontal structure is divided into three types: grassland,sparse forest,and dense forest.Field investigations show that grassland is only present in the third Xiangya Hospital.The sparse forest space can be seen in each site,and the dense forest space is located in each site.Changsha Central Hospital,Mawangdui Sanatorium and Carnation Sanatorium exist;the vertical structure is divided into four types: Joe-Shrub-Grass,Joe-Shrub,Joe-Grass,and Shrub-Grass.Among them are the Third Xiangya Hospital and Changsha Central Hospital.The joe-shrub-grass structure can be seen in the Carnation Sanatorium.The joe-shrub structure and the shrub-grass structure can be seen in every site surveyed.The joe-grass structure can only be seen in the Second Xiangya Hospital,Changsha Central Hospital,and Ma Wangdui Nursing Home,Carnation Nursing Home and Hunan Cancer Hospital.3.Using AHP analytic hierarchy process to evaluate the landscape of 8 sites,aiming at species diversity,life-form structure diversity,community richness,native plant ratio,plant species richness,plant growth status,plant maintenance and pruning status,plants A total of12 indicators of configuration,shade coverage,plant landscape space size,sense of security,comfort,and pleasure get the corresponding weight values: 5.049%,2.344%,8.295%,1.981%,10.106%,2.789%,1.921%,27.622%,3.171%,18.439%,so as to obtain the important factors affecting the quality of the landscape.There are 4 important factors,namely the abundance of plant species,the configuration of plants,the size of the landscape space,and the sense of relaxation.The remaining 8 items are all It is the second most important factor.4.Using the POE post-appraisal method,the subjective evaluation of the plant landscape space was divided into 8 specific questions through questionnaire surveys and the results showed that Changsha Central Hospital ranked first in all aspects,and the overall satisfaction was the highest,The satisfaction with the outdoor plant landscape of Xiangya Hospital is the lowest.At the same time,from the user’s point of view in the form of behavior observation,a systematic evaluation of the facilities that have been designed and being used is carried out.5.Combining the summarized theoretical viewpoints and actual research results to summarize the four existing problems of the outdoor plant space in Changsha City Hospital,put forward the optimization strategy of the rehabilitation garden,explore the outdoor landscape design strategy of the hospital,and propose improvement strategies for the problems.On the one hand,this research conducted a detailed investigation on the status quo of the medical environmental rehabilitation plant landscape in Changsha City.On the other hand,this research evaluated the outdoor plant landscape of the Changsha Hospital through a comprehensive statistical evaluation method.The evaluation results obtained by data expression are expected to provide a theoretical reference for the sustainable development of the outdoor plant space of the Changsha hospital and the improvement and transformation of the plant landscape. |
