Analysis Of The Phenological Periodand The Landscape Of Wetland Plants In Zhuji Wetland

The wetland is a kind of very important ecosystem on the earth, especially in urban area. It not only provides a great deal of natural resource, but also play an important role in ecological benefits and functions of landscape. Plants are important element of urban wetland park. The planning and design of urban wetland park depend on the diversity of plants, especially aquatic plants. While their function on landscape and ecology being deeply understood, aquatic plants are used more and more widely on the wetland. So, it would be necessary and helpful to execution analysis on the phonological period of plants in wetland. In this dissertation, Xishiguli urban wetland, as an example, the phonological periods of the aquatic plants involved were investigated. Hopefully, this can be somewhat useful for construction of some urban wetland parks. The main results are summarized as follows:1. After reading the previous literature on wetland, we proposed the methods and the content of this dissertation.2. A detail analysis on current status of plants in Zhuji's urban wetland park was conducted, besides outside investigation and material analysis3. The plants of the wetland were investigated. (1)There are about 68 species of aquatic plants, which belong to 36 families. Among these species,54 are emergent plants,4 floating-leaved plants,4 floating plants and 6 submerged plants. (2)However, evergreen species for aquatic plants are rarely, so the winter plants are not enough. (3)There are more wild hydrophytes get the value and application, but the analysis of the phenological of dominant of aquatic plants in Xishiguli urban park is still short. The color of flower and color of leave and high and the proper depth range of some aquatic plants were also investigated.These results are beneficial to planting design and utilization of aquatic plants.4. Based on the research, this study has surveyed the plant communities of typical disposition models on Xishiguli urban park. The result is that:(1) The configuration model of wetland plants are trees+herbaceous, there are the largest proportion. (2)Trees and shrubs of evergreen trees too few, shrubs less, so should increase the shrub layer plants shrubs and grass to build the configuration mode to create a more stable plant. (3) The richness and variousness of herbage on bank is higher than that in water. Aquatic plant species and quantity of Xishiguli urban park should be improved.5. In the field and on the basis of the literature study, we analysed wetlands plants and its problems of Xishiguli urban park, Proposed optimization Xishiguli urban Park Wetland landscape proposals.
