A Preliminary Study On Plant Landscape Of South Asia Tropical Karst Plant Garden-Guangxi Longtan Park As An Example

South China karst partition is one of the most concentrated area of karst distribution in the world,is known for its karst landscape in guangxi,the south Asian tropical karst plant research in karst area,rocky desertification prevention and control of soil erosion research has very important significance,and karst botanical garden construction will help more in-depth understanding,collect and study plant resources in karst region,and karst botanical garden plant landscape botanical garden construction is different from other gardens of important factor.Taking carst botanical garden landscape construction as the research key,by MAO LAN nature reserve in guizhou,Guilin botanical garden,iuzhou longtan park,natural mountain vegetation analysis based on karst landform and vegetation landscape within the areas mentioned above,the karst plant landscape,and combined with shigeru for visitors to protected areas of the plant landscape experience questionnaire survey result,the following conclusions:(1)karst under the condition of natural plant community composition is complex,relative to the construction of an artificial plant community,natural community formed by natural selection,more in line with the ecology principle,has high scientific;(2)under the natural state of karst forest,interlayer plants is very rich,this is the plant landscape of karst features,but too much interlayer plants will lead to lack of plant landscape aesthetic teeling;(3)to protect good regional complex and stable plant community,most plant community and human disturbance more areas are composed of shrubs vine,lack of tree layer,in terms of landscape change in abundance;(4)in the south Asian tropical karst plant landscape construction have to be cut on the natural landscape plant community,in the guarantee of scientific meet the aesthetic needs of people at the same time;(5)the karst area of soil and water loss,in the plant landscape construction to take the necessary method such as artificial building enclosures in ease,planting difficult problems such as soil and water loss.Moreover this article also guangxi karst region common plants and investigate the plant species of the longtan park,from the Angle of physiognomy types and ornamental plants were analyzed,and combined with the reserves and park plant landscape investigation results,explore the south Asian tropical karst botanical garden plant landscape construction ideas,recommendations of karst landscape plant construction,and take the guangxi liuzhou longtan park as an example,put forward preliminary idea of karst build south Asian tropical botanical garden plant landscape,combined with the campus LeiTan scenic spots around the plant landscape renovation project implementation,the application of the theory research of the paper to the actual work,the plant landscape of the area is larger difference.This article innovation point lies in:(1)the various types of botanical garden appeared frequently in people’s life,but it is still not built for carst region the botanical garden plant,only a handful of botanical garden with plants exhibit karst,based on the karst and karst landform and karst plant landscape of combination of theory and practical investigation,innovative research on south Asian tropical karst botanical garden plant landscape,and applies theoretical research results to the actual landscape construction work.(2)in guangxi region due to historical reasons in study of angiosperm classification still followed the qin system,but the system in plant evolution system show and there are many defects on the plant landscape construction,this paper,the selection of innovative krona qwest classification system for the layout of the karst plant species-divided gardens design,combined with the longtan park original ethnic customs and cultural history,decorate each gardens plants according to their ecological habits and sequence evolution system of decorate his way to the Lord an park,make the subtropical karst areas of plant landscapes represent the subtropical karst landscape garden plants.
