| Guangdong is located in tropical and subtropical areas,with abundant rainfall and abundant plant resources.The garden plant landscape has distinctive local characteristics.As a typical representative of Lingnan gardens,Guangdong gardens have led the inheritance and development of Lingnan gardens to a certain extent in history.Since the reform and opening up,Guangdong,as a forward position,has fully exchanged Chinese and foreign garden culture.While inheriting the excellent classical garden culture,it has also absorbed a large number of western excellent garden culture,and constantly built a richer and more diverse garden plant landscape in the construction of modern gardens.At present,China is continuously promoting the construction of ecological civilization.It is required to strengthen the construction of urban and rural park green space,and put forward the requirements of scientific greening.Therefore,based on the landscape industry in Guangdong,through the comparative study of the current situation of classical and modern landscape in Guangdong,we can achieve the purpose of comprehensively understanding the current characteristics of landscape plant landscape in Guangdong,discovering and improving the existing problems,which is conducive to the scientific construction of urban and rural greening in the next stage and the integrated development of classical and modern landscape plant landscape in Guangdong,It is conducive to the inheritance of garden plant culture.Firstly,this paper reviews the development process of classical gardens and modern gardens in Guangdong,clarifies the development context of current gardens,and combs the main manifestations and origin of classical gardens and modern garden plant landscape.Then,through the selection of 20 current gardens,including 10 classical gardens and 10 modern gardens,the field investigation is carried out on their garden plant species,garden layout and plant landscape expression forms.According to the investigation results of plant species,from the application homogeneity of garden plant species,species diversity index,tropical plant landscape construction,flower viewing plants and their flower color categories This paper makes a comparative analysis of the current landscape plant landscape of classical gardens and modern gardens from nine aspects: color leaf and autumn leaf plants,the proportion of local plants,the proportion of fragrant flowers,the identification of toxic plants,low maintenance and sustainable landscape plant configuration.The analysis results show that the plant landscapes of classical gardens and modern gardens are generally rich in plant categories and landscape levels.Although they have different emphasis on the application preference of plant species and the expression form of group landscape,at the same time,the plant landscapes of the two have the performance of integrated development.According to the current situation investigation and analysis results,the evaluation index system of garden plant landscape is constructed by using analytic hierarchy process,and the concept and calculation method of garden plant impact index are put forward according to the index system,which can make a more comprehensive and objective qualitative and quantitative analysis of garden plant landscape,and intuitively compare the advantages and disadvantages of different garden plant landscapes,According to the analysis of various factors in the index layer of the index system,the restrictive factors affecting the landscape can be optimized.The garden plant landscape evaluation index system and garden plant impact index can provide a basis for optimizing the garden plant landscape construction in the future garden construction and landscape improvement.Finally,according to the investigation,analysis and evaluation of the current landscape,the problems existing in the current situation of landscape plant landscape in Guangdong are summarized,and the corresponding measures and suggestions are put forward. |
