The Research On The Landscape Plants Divisions In Guangxi

With the development of the landscape, the species of the landscape plants become more in Guangxi.Because of the lack of the scientific, artistic and creative, the landscape exists the monotonicity and unreasonable. Based on the investigation on the present situation of the landscape plants in the14th cities of Guangxi, the paper analysis the division and plan of the landscape plants in Guangxi, the research results include five parts as follows:The first is the analysis on the application status of the garden plants in Guangxi, which include the species of the cities landscape plants, the composition of the family and genera, the ornamental characters and the application types of the landscape plants. According to the statistical analysis, The results showed that there are916species landscape plants, belonging to148families and505genera; The plants whose leaf, flower, fruit and rhizome have ornamental value are636species; The plants applied to the solitary tours is the most, up to533species, and the vertical greening, water greening and the beds glasses plants are less than50. In addition, this paper also analysis the problems existed in the gardening of Guangxi, and put forward the corresponding proposals.The second is the analysis on the divisions index, and choose the climatic regionalization, vegetation division, the administrative division as the first index; the topography, the economic environment and greening development of the urban.The third is the comprehensive analysis on the division index, and overlay the sector maps to determine the boundaries, Guangxi landscape plants are divided into three large districts and five small districts as follow:IA Northeast and Northern Karst basin mountain landscape area; IB Midland mountain basin landscape area; IIA Southeast hilly landscape area; ⅡB Southwest Karst mountain landscape area; Ⅲ South coastal terrace landscape area. In addition, this paper also make statistical analysis on the plants species, native plants, life forms and plant traits composition.The fourth is to plan urban fundamental key plants,key plants and general plants of each zoning area based on the natural conditions and landscape plant status in Guangxi.The fifth is to study the potential values and the evaluation system of Guangxi plants resources, and analysis the landscape application potential of the promoted plants、general plants、regional characteristic and rare-endangered plants.In summary, based on the investigation and analysis on the situation of landscape plants in Guangxi, combined with the analysis on the regionalization indices, the paper researchs the regionalization and plan on the landscape plants, in order to advoid the non scientific in the landscape plant planning, and enhance the urban gardening construction level. Finally there is a scientific basis provided for the building of local characteristic and sustainable development landscape.
