Studying on Qinglongshan Forest Park in Wuhan by typical plot method, 15 typical plots in the park were investigated, and the species richness index, diversity index, evenness index, frequency and important value index were calculated. The results showed that there were 139 species of woody plants belonging to 46 families and 97 genera, including 41 species of evergreen trees, 32 species of deciduous trees, 62 species of evergreen shrubs, 25 species of deciduous shrubs, and 4 species of bamboo belonging to 1 family, 3 genera. Species richness index and Simpson diversity index were all expressed as tree layer > shrub layer, evergreen species > deciduous species. Pielou evenness was tree layer > shrub layer. This study can provide some reference for understanding the existing plant status of forest parks, carrying out science popularization, scientific research, protection and improvement of forest landscape quality.

This study is to determination of active medicinal components in Lonicera macranthoides. The results of High-performance liquid chromatography showed that the contents of chlorogenic acid were as follows: Baiyun: 6.297%, jincuilei: 5.293%, yincuilei: 5.288%, common variety: 7.455%, common variety (after flowering): 4.140%. The contents of Luteolin in different Lonicera macranthoides varieties were as follows: Baiyun: 0.0264%; Jincuilei: 0.0573%; Yincuilei: 0.0347%; common variety: 0.0394%; common variety (after flowering) : 0.0197%.

Using line method and typical sample method, the plant resources of the Jinyin Lake National Wetland Park were investigated in detail. There were 62 families, 113 genera and 135 species of seed plants. 4 families and more families were the dominant families of seed plants in this area. 1 genera were the main reasons for the diversity of seed plants in this area. The 62 families can be divided into 9 areal types and 5 forms, of which tropical families accounted for 61.36% of the total number of non-cosmopolitan families. The 113 genera can be divided into 13 distribution types and 2 variants, of which the temperate distribution is 61.39% of the non-cosmopolitan genus. The 135 species can be divided into 7 distribution types, mainly in the subtropical monsoon climate area, accounting for 45.19% of the total species. The research results provide basic information and scientific basis for the protection and management of plant diversity resources in the Jinyin Lake National Wetland Park.

In recent years, in order to provide theoretical and scientific basis for the protection and rational utilization of plant resources in Lon longquan mountain gquan Mountain, the seed plants in Longquan Mountain were taken as the research object, and the field investigation was carried out by using the method of line plus typical sample plot, so as to further study the characteristics of investigated area were further studied. The results show: There are 231 species of 191 genus in 90 families, including 5 families, 9 genus and 11 species of gymnosperms, and 82 species of 182 genus and 85 species of angiosperms. The 14 distribution types of seed plants belong to the statistics: North temperate distribution There are 72 genus, accounting for 37.7% of the total genus of the area, reflecting the obvious north temperate nature of the flora. In addition, there are many ancient taxa and Cretaceous and Tertiary relict plants. There are 163 genus of single genus and genus genus, accounting for 85.3% of the total genus of the region, indicating that the plant origin is relatively old, there are 7 genus in China, which indicates that the unique phenomenon exists, but it is not obvious.

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.

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.
