Plant Diversity And Landscape Evaluation Of The Nanshui Lake National Wetland Park

Nanshui Lake National Wetland Park with grand ecological value for its Water Source Protection Area and National Wetland Park status. Based on field survey data, this research studied plant species diversity, diversity of plant communities, plant landscape patterns, flora of seed plant, landscape quality assessment by means of resources surveying, diversity measurements and analysis, and landscape evaluation.Results are as follows:(1)There are 983 vascular plants in Nanshui Lake National Wetland Park, which belong to 177 families and 585 genera, and accounted for 13.93% of the vascular plants in Guangdong Province.(2)There are 914 seed species in Nanshui Lake National Wetland Park, which shows a relatively clear tropical nature and some infiltration of temperate elements.(3)There are 8 kinds of typical plant communities in Nanshui Lake National Wetland Park. It shows that by calculating and anlysing of species richness, Shannon-Wiener index and Simpson dominance index, plant communities have high level of overall diversity in Nanshui Lake National Wetland Park.(4)There are 5 kinds of main plant landscapes in Nanshui Lake National Wetland Park. Established a preliminary landscape of Nanshui Lake National Wetland Park a comprehensive evaluation system. The result shows that the quality of plant landscapes is in middle level, which Ⅱand Ⅲclass takes the main position.
