【摘要】：城市绿地是城市主要生态服务系统之一,而城市景观绿地不仅体现一个城市的生态风貌,还能反映一个城市的文化风貌。但近年来随着社会经济的快速发展及城镇化的不断深化,城市人地矛盾日益增长、城市工业污染加剧、交通拥堵严重、生活污染导致城市脏、乱、差等问题致使城市生态环境及人居环境恶化,严重影响城市人口生活质量。合理规划城市景观绿地能改善城市生态环境、美化城市面貌,对贵阳市建设全国生态文明示范城市具有促进作用。本文运用市场价值法、影子工程法、碳税法、美景度SBE法、AHP层次分析法、SWOT分析法等方法分别得出研究区生态服务价值和美景度,确定了指标体系中各指标权重,阐述了生态服务价值及美景度的耦合度及耦合协调度,分析了研究区当前景观绿地规划现状,并提出优化建议。通过对计算结果的研究,得出如下结论:(1)对于喀斯特山区城市而言,景观绿地各项生态系统中,维持生物多样性和土壤保持生态服务功能最明显,湿地景观生态系统生态服务价值量最大,道路绿地生态服务价值量最小。(2)研究区整体景观绿地美景度一般,一定程度反映出贵阳市整体景观绿地规划还有待优化。尤其居民生活日常接触最多的道路景观绿地,更需要通过优化进一步提高生态效益和景观效果。(3)研究区中花溪湿地公园生态服务价值——景观美景度耦合度最高,生态效益和美学效应也较好。金阳北路最差,反映出贵阳市道路景观绿化还不完善,协调好生态效益与景观效应关系可作为道路绿化的重点。(4)城市绿地的主要服务对象是市民,因此在进行景观绿地规划时,必须要充分考虑“以人为本”。根据美景度评分调查发现居民对城市景观绿地的审美喜好偏向于植物与水体兼有,且与周围自然环境相协调,具有一定设计感的绿地景观。
[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.
