The purpose of this study is to explore the landscape quality of aquatic plants in the landscape water in Wuhan, reveal the rules of its construction, and provide some basis for landscape design and evaluation of aquatic plants. Based on the six representative parks in Wuhan, 9 quantitative and qualitative indexes were selected, and the evaluation model was constructed by using the analytic hierarchy process(AHP). The results showed that a total of 36 species of aquatic plants were found, mainly emergent plants. The five research objects are in grade Ⅰ and Ⅱ, and only the aquatic plants in Shahu Park are at the level of level Ⅲ, which indicates that the quality of aquatic plants in the main landscape water of Wuhan is at an excellent level. The evaluation model can objectively be used in the Wuhan landscape water body . Based on the evaluation results, 3 excellent aquatic plant plots are recommended.
Park green space is an important part of garden green space, concentrated expression of the diversity of urban plants. In order to explore the diversity of plants in the park, a typical site in Zhongshan Park in Wuhan was selected for this survey. The species importance, richness index, diversity index and evenness index were used to analyze the characteristics of plant diversity.There are a total of 184 plants of 114 genera and 64 families in Wuhan Zhongshan Park. Among them, there are 86 species of plants of 40 families and 64 genera, 60 species of plants of 26 families and 38 genera, and 26 species of herbs, 11 families and 15 genera.The richness was herb layer > tree layer > shrub layer.Pielou uniformity was herb layer > tree layer > shrub layer;Shannon-wiener diversity was herb layer > tree layer > shrub layer.Simpson diversity was herb layer > tree layer > shrub layer.The diversity of herbaceous plants in the park is high, and the index of shrub layer is generally low, with few species. Plants in the park grow well, some plants are not evenly distributed.
Based on route and sample-plot survey, plant resources of Liangzi Lake Wetland Nature Reserve were investigated. The result showed that there were 503 species of spermatophyte belonging to 296 genera of 86 families. There were 5 species under national first and second level protection. The dominant families of spermatophyte contained 20 species and above. The dominant genera of spermatophyte contained 4 species and below. The 86 families of spermatophyte can be divided into 7 distribution types and 4 variants. Tropic distribution type was dominant, accounting for 70.83% in total (excluding cosmopolitans). The 296 genera of spermatophyte can be divided into 14 distribution types and 9 variants. Temperate elements were a little more than tropical elements, accounting for 50.84% and 49.16% in total (excluding cosmopolitans) respectively. Reserve had 3 Chinese endemic genera, reflecting certain ancient and relict. The purpose of the research is to provide background information and scientific basis for the protection, construction, management and rational utilization of plant resources in the reserve.
