| 中文摘要: |
| 通过以安庆市城区的三大公园:菱湖公园、市民广场、新河公园为研究对象,对各公园水体的水生植物进行样地调查,并运用层次分析法对安庆市公园景观水体水生植物应用现状及配置状况进行综合评价。结果表明:调查区域共有水生植物33种,分别隶属于23科32属,主要以挺水植物为主,湿生、浮水、漂浮、沉水植物为辅,其中以莲、浮萍、空心莲子草最为常见。三大公园的水景配置综合评价结果均为三级中等水平,在三者中新河公园水生植物配置综合指数最高,市民广场次之,菱湖公园最低。同时,与同一评价体系的淀山湖、上海植物园进行更深入的比较发现,挺水植物频度可能是景观水体综合评价结果的重要影响因子之一,且20%挺水植物频度也可能是它的一个阈值,这为今后水体景观的设计与实施提供了一定的理论依据,具有较强的实操意义。 |

| Selecting three major parks in Anqing City (Linghu Park, Citizen's Square and Xinhe Park) as the study objects, the aquatic plants in the water bodies of the parks were investigated. The application status and configuration mode of aquatic plants in the landscape water of Anqing Parks were comprehensively evaluated by analytic hierarchy process (AHP). The results showed that there were 33 species of aquatic plants in the investigated area, belonging to 32 genera in 23 families. The main species were emergent plants, supplemented by wet plants, floating plants, submerged plants. Among them, Nelumbo nucifera, Lemna minor, and Alternanthera philoxeroides were the most common. The comprehensive evaluation results of waterscape configuration in the three parks were all at middle level. Among them, the comprehensive index of aquatic plant allocation in Xinhe Park was the highest, followed by Citizen's Square, and Linghu Park. At the same time, through a more in-depth comparative study with Dianshan Lake and Shanghai botanical garden of the same evaluation system, it was concluded that the frequency of emergent plants might be an important factor in the comprehensive evaluation results of landscape water body, and 20% of the frequency of emergent plants might be a threshold value, which provided a theoretical basis for the design and implementation of water landscape in the future, and had a strong practical operability. |
