| In this paper, the research object is Tianxiadiyi Chuen scenic area of artificial plant community landscape, in based on the field investigation, ecological characteristics of the plant community and according to the research results to extract the factor of landscape aesthetics, plant communities of the scenic spot were landscape aesthetic evaluation. The main conclusions are as follows:1, of artificial plant communities in the area of plant families and genera distribution, analysis of community types and species diversity, plant species ratio analysis, plant using frequency analysis, plant height distribution analysis, plant diameter class distribution analysis, space types of ecological factors were studied. The results showed that:(1) of the 54 samples, there were 81 species of plants belonging to 42 families and 109 genera;(2) there are 7 types of community types, with deciduous broad-leaved forest and mixed coniferous forest dominated, in which the average richness of deciduous broad-leaved forest is the highest, which shows that the community type of the scenic area of Ji’nan city has retained the characteristics of the regional plant;(3) in the proportion of species, in addition to the proportion of the total scenic area of evergreen and deciduous plants is very suitable for outside, other species ratio:tree layer should increase deciduous plant species, shrub layer and ground is layer should increase the number of evergreen species. At the same time, the arbor, shrub species ratio was adjusted to 1:3, and the proportion of the total area of evergreen and deciduous plants maintained in 1:2.3. Should also increase the types of aquatic plants; seasonal, scenic summer flowering plants; ornamental characteristics, view fruit view leaf plant application.(4) the frequency of plant application, the high frequency of plant applications is not much, that the landscape plant community landscape changes rich;(5) the height distribution of plant communities in the area should be increased for the first stage low ground cover plants and aquatic plants as well as the application of grade â…¢ main flowering and evergreen small trees;(6) Qiao Muceng’s structure distribution shows that most of the plant communities in the scenic spot is in the youth, the landscape will still have a great change.(7) the plant communities of the sample will be divided into two types of land artificial plant communities and shore water artificial plant community, terrestrial plant communities and semi open space, closed space, space under the crown, the waterfront of artificial plant community is divided into strip, U-shaped, island shape, based on analysis the construction features of each type.2, the landscape aesthetic evaluation of plant communities. The results are as follows: the average landscape quality of the plant communities in the area is gradeâ…¡, and the landscape quality is better. Carries on the analysis to the â… , â…¡, â…¢ the quality grade botanical community and its characteristics, all the evaluation factors of level I plots were good, better grade â…¢ land of level â…¡ plots partial evaluation factor:single plant species or species is less; the single structure of plant level; landscape monotonous. The sort of different plant community park landscape quality:Baotu Spring Park> Darning Lake Scenic Area> scenic spots around the city> Heihu Quan Park> five Longtan Park. The value of each evaluation factors of scenic plant communities in the average score of comparison, ecological beauty level, scoring the lowest for C3 native plant richness; landscape beauty levels scored the lowest C7 ornamental characteristics of diversity, and lower scores, indicating that area of the plant community of ornamental characteristics is not very rich. According to the research and analysis of artificial plant community in spring scenic area, the best in all the land problems, and put forward the optimization strategies and recommendations. |
