Research On Plant Landscape Of Modern Agricultural Science And Technology Park Of Nanjing Cuigu

With the development of urban modernization and the improvement of people's living standards,modern agricultural science and technology parks have been vigorously developed.During the development of modern agricultural science and technology park,there are many problems in plant landscape planning.In this study,we take the Nanjing Cuigu modern agricultural science and technology park as an example to study its plant landscape.On the basis of understanding the development of modern agricultural science park at home and abroad as well as the theory of plant landscape design and planning,the plant species composition,family,community structure and dominant species of the Nanjing Cuigu modern agricultural science and technology park are analyzed by field investigation.The plant configuration in the main areas of the park was studied,and the quantity and polymorphism of plant configuration pattern in the park were analyzed.Secondly,on the basis of the survey data,the landscape,ecology and function of the landscape,ecological and functional three levels of the beauty of the comprehensive evaluation and analysis,choose the best plant configuration combination.Finally,on the basis of the comprehensive evaluation and analysis of the beauty degree,the main points of the plant landscape configuration of Nanjing Cuigu modern agricultural science and technology park are summed up,and the optimization measures are put forward in view of the problems and deficiencies in the plant landscape configuration,and the hope is of great significance to the future plant landscape construction of the modern agricultural science and technology park.The main results of this paper are as follows:(1)Some of the scenic spots of the modern agricultural science and technology park are still under construction,but the overall construction of the park has basically been completed.There were 183 species of plants belonging to 76 families and 138 genera.There are 32 families,56 genera,67 species of trees;there are 26 families,46 genera and 56 species of shrubs;there are 14 families,24 genera and 29 species of herbs;there are 12 families,14 genera and 14 species of aquatic plants;The vines have 12 species,10 genera and 7 families;there are 5 species of bamboos,2 genera and 1 families.(2)The plant landscape community structure of the agricultural science and technology park is mainly composed of tree,shrub grass complex and tree grass type,followed by arbor type and tree irrigation type.Most of the plant landscape communities are deciduous trees,and perennial herbs are mostly.The quantity structure is represented as tree:Irrigation:grass is 1:0.84:0.90;evergreen tree:deciduous 1:2.53;evergreen shrub:deciduous 1:1.33;native tree species in Nanjing:foreign tree species 1:1.26.(3)Plant landscape evaluation based on the AHP method,integrated landscape,ecological and functional indicators of the three levels of the park evaluation of the 200 community structure of the park selected 20 typical plant communities,and finally selected 6 landscape evaluation indicators,the park 20 groups of different plant landscape configuration model of the beauty scale,thus contributesthe evaluation system of scenic beauty of plant landscape in Cuigu modern agricultural science and technology park.(4)On the basis of field investigation and combined with the evaluation and analysis of beauty degree,the problems of plant landscape in the modern agricultural science and technology park of Cuigu are revealed,and the main points of plant landscape configuration are explained from three levels.The strategy of optimization and improvement is put forward for the existing shortcomings,and several optimal plant configuration combinations are recommended for the 4 main regions.
