【摘要】：公园植物群落是公园景观的重要组成要素,其景观质量的优劣决定了公园整体景观质量的好坏,因此进行景观评价研究十分必要。本文以西安市公园的典型植物群落为研究对象,基于西安市公园绿地的实地调查,对调研的58个植物群落运用层次分析法和美景度评判法进行景观评价。结果如下:1.本次共调研西安市11个公园的58个植物群落:(1)共有植物145种,隶属于51科101属。(2)乡土植物69种,比例为47.59%。(3)调研中共出现5种群落类型:以落叶阔叶林为主,其次是常绿落叶阔叶混交林,针阔混交林第三,而常绿针叶林和常绿阔叶最少。(4)群落主要以“乔—灌—草”复层结构模式为主。(5)调研群落的Simpson多样性指数平均为0.7337,整体水平较高。2.景观评价:(1)应用层次分析法建立了3个准则10个指标的评价模型,为西安市公园植物群落景观评价提供了方法。通过专家拟定各评价指标及其权重,综合评价得出了植物景观的质量等级:优、良、中、差四质量个等级的植物群落分别占总数的12.1%、74.1%、10.3%、3.5%,说明西安市公园植物群落景观整体质量良好。(2)应用美景度评判法,对群落照片评分算出美景度值,结果表明:美景度值越高,植物群落景观效果越好。(3)虽然这两种方法的评价依据和形式有所不同,但是从评价结果来看,其一致性较高。据此选取了3个典型植物群落,分析了其植物景观营造中的优点和不足,并给出了合理的优化建议。3.基于以上调查和景观评价,对研究数据进行了总结分析,从西安市公园植物群落景观建设的整体考虑,有针对性的提出了西安市公园植物群落景观优化建议,以期为城市公园植物景观的营造提供参考依据。
[Abstract]:The plant community of the park is an important element of the park landscape, and the quality of the landscape determines the quality of the overall landscape of the park, so it is very necessary to study the landscape evaluation. Taking the typical plant community of Xi'an Park as the research object, based on the field investigation of park green space in Xi'an, 58 plant communities were evaluated by AHP and beauty degree evaluation method. The result is as follows: 1. There are 145 species of plants belonging to 51 families, 101 genera and 2 species of native plants in 58 plant communities in 11 parks of Xi'an. The proportion is 47.5910%.) there are 5 community types: deciduous broad-leaved forest is the main type. The second was evergreen deciduous broad-leaved mixed forest, and the third was coniferous and broadleaved mixed forest. The average Simpson diversity index of evergreen coniferous forest and evergreen broad-leaved community was 0.733 7, and the whole level was higher than that of "Arbor, shrub and grass". (1) Analytic hierarchy process (AHP) was used to establish the evaluation model of 3 criteria and 10 indexes, which provided a method for landscape evaluation of plant community in Xi'an Park. Through the expert to draw up each evaluation index and its weight, the comprehensive evaluation obtained the plant landscape quality grade: excellent, good, medium, The plant communities with four grade difference in quality accounted for 12.1g / 74.1and 10.3 / 3.5respectively, indicating that the overall quality of the plant community in Xi'an Park was good. (2) the beauty degree evaluation method was applied to calculate the beauty degree value of the community photos. The results showed that the beauty degree value was higher, the higher the landscape quality was, the higher the landscape quality was. Although the evaluation basis and form of these two methods are different, but from the evaluation results, its consistency is high. Based on this, three typical plant communities were selected, the advantages and disadvantages of plant landscape construction were analyzed, and reasonable optimization suggestions were given. Based on the above investigation and landscape evaluation, the research data are summarized and analyzed. From the overall consideration of the landscape construction of the plant community in Xi'an Park, the suggestions for landscape optimization of the plant community in Xi'an Park are put forward. In order to provide reference for the construction of urban park plant landscape.
