Plant Diversity Research And Plant Landscape Analysis In Hohhot Nanhu Wetland Park

The plant is one of landscape elements of city wetland park, also the important element of the wetland characteristics.Diversity of plant species and quantity is an important index to decide the wetland plant landscape richness, the quanlity of plant configuration impact plant landscape quanlity of wetland park.This survey based on plant species of Nanhu wetland park in Hohhot to analysis plant diversity of wetland park.Through the diversity indexes, make plant landscape evaluation of each area and put forward some suggestions. The results are as follows:(1) In Hohhot Nanhu Wetland Park, there are 80 species plants, belonging to 34 families and 65 genera, including 2 families,4 genera and 6 species gymnosperms and 32 families,61 genera and 74 species angiosperms; In all angiosperms, monocotyledons are 8 families,20 genera and 21 species and dicotyledons are 24 families,41 genera and 53 species.

The species of tree are 15 species, shrub are 13 species.(3) The differences of function regions of Hohhot Nanhu Wetland Park have different plant diversity index in.The 1 area of tree layer and bush layer are high plant diversity index, the plant diversity index of herb layer is small and herb layer is less plant species.The 2 area and 3 area are high Margalef index and Shannon-Wiener index and plentiful species,3 area herb layer Shannon-Wiener index is the lowest and herb layer is less plant species.The 4 area and 6 area are higher plant diversity index in tree layer and herb layer, lower plant diversity index in bush layer and less plant species.The 5 area herb layer are high plant diversity and plentiful species, tree layer and bush layer are lower plant diversity and less plant species.(4) Hohhot Nanhu Wetland Park have 80 kinds of plants.The main ornamental plant have 35 species flowering plants, there are 7 kinds of tree,10 kinds of shrub and 18 kinds of herb; Fruit plants have 15 species, there are 7 kinds of tree,2 kinds of shrub and 6 kinds of herb; Foliage plants have 22 species, there are 3 kinds of tree,4 kinds of shrub and 15 kinds of herb; Tree form plant have 17 species, there are 13 kinds of tree,4 kinds of herb.
