Study On Plants Landscape Diversity Of Xiazhu Lake Wetlands

Xiazhu Lake is the fifth largest inland lake with rich plant resources and diversified Landscape in Zhejiang Province.It’s a natural wetlands in the Yangtze River Delta Region of China with a high ecosystem diversity and a strong undisturbed native state.Based on field survey data,this research studied wetland plant species diversity, diversity of plant communities, plant landscape patterns, landscape quality assessment by means of resources surveying, diversity measurements and analysis, satellite remote sensing and landscape evaluation.Results are as follows:(1)There are390vascular plants in Xiazhu Lake wetlands,which belong to123branches. Total number of species accounted for35.36%of the wetlands vascular plants in Zhejiang Province and was15.32%higher than the Xixi Wetlands.In the sort of families, genera, species dominance,it’s dicots>monocots>ferns>gymnosperms.The dominant families are Asteraceae.Poaceae,Fabaceae. Rosaceae,Labiatae,Liliaceae and Rubiaceae.(2)There are14typical wetland plant communities in Xiazhu Lake wetlands.It’s show that wetland plant communities of Xiazhu Lake have high levels of overall diversity by calculating of species richness index, Shannon-Wiener index and Simpson dominance index, but there is still much room for improvement.(3)By observing the landscape area on remote sensing image and evaluating plant landscape quality from ecological, ornamental, Tour level,it shows that Joe shrub plant natural landscape and artificial plant landscape are main components in the macro landscape pattern of wetlands and the landscape quality of the wetland plants showed a higher level.(4)Ecological and environmental protection should be working in the first place in the protection process of plant landscape diversity.In addition,we should gradually improve the construction of plant resources database, focus on wetland plant communities ecological maintenance, strengthen wetland plants landscape original ecological protection.It’s necessary that building wetland plants landscape diversity protection mechanisms which are Real-time data monitoring-Data comparison-Formulation and implementation of protective measures-Real-time data validation.
