基于生態(tài)服務(wù)價(jià)值與美景度的城市景觀綠地規(guī)劃研究
[Abstract]:Urban green space is one of the main urban ecological service systems, and urban landscape green space not only reflects the ecological style of a city, but also reflects the cultural style of a city. However, with the rapid development of social economy and the deepening of urbanization in recent years, the contradiction between people and land in cities is increasing day by day, the urban industrial pollution is aggravated, the traffic congestion is serious, and the life pollution causes the city to be dirty and chaotic. The quality of life of urban population is seriously affected by the deterioration of urban ecological environment and human settlement environment. The rational planning of urban landscape green space can improve the urban ecological environment, beautify the city appearance, and promote the construction of the national ecological civilization demonstration city in Guiyang city. Using the methods of market value method, shadow engineering method, carbon tax law, beauty degree SBE method and AHP analytic hierarchy process (AHP) method, this paper obtains the value of ecological service and the beauty degree of the study area, and determines the weight of each index in the index system. This paper expounds the coupling and coordination degree of ecological service value and beauty degree, analyzes the present situation of landscape green space planning in the study area, and puts forward some suggestions for optimization. Through the study of the calculation results, the following conclusions are drawn: (1) for the karst mountain cities, the maintenance of biodiversity and the ecological service function of soil conservation are the most obvious in the ecosystem of landscape green space. The ecological service value of wetland landscape ecosystem is the largest, and the value of ecological service of road green space is the smallest. (2) the overall landscape beauty degree of the study area is general, which reflects to a certain extent that the overall landscape green space planning of Guiyang city needs to be optimized. Especially, the road landscape greenbelt, which has the most daily contact with the residents, needs to further improve the ecological efficiency and landscape effect through optimization. (3) Huaxi Wetland Park in the study area has the highest value of ecological service-the highest degree of landscape beauty coupling. Ecological benefits and aesthetic effects are also good. Jinyang North Road is the worst, which reflects that the road landscaping in Guiyang is not perfect, and coordinating the relationship between ecological benefit and landscape effect can be regarded as the key point of road greening. (4) the main service object of urban green space is citizens, so when planning landscape green space, We must give full consideration to "putting people first". According to the survey of the beauty degree, it was found that the residents' aesthetic preference for the urban landscape green space was inclined to the green landscape with both plants and water bodies, and coordinated with the surrounding natural environment and had a certain sense of design.
