Study On Ecological Design And Application Of Urban Waterfront In Shanxi Province

Urban Waterfront as a business card of the city,waterfront development is imperative.Due to its unique ecological sensitivity and complexity of the waterfront development of eco-design it is particularly important.In the country are in the development of the background of the waterfront,for all the design are hanging "ecological" under the premise of Shanxi Province,the waterfront development of the park has not done ecological design,and ecological design to what extent,Is the main purpose of this paper.The study has a certain significance for the ecological design of the future waterfront development in Shanxi Province.In this paper,three representative waterfront parks in Taiyuan(Fenhe Park in Taiyuan,Xiaohe Wetland Park in Xiaoyi and Changyuanhe Park in Qixian)in Shanxi Province were selected,and the sampling method(30m × 30m)and landscape pattern analysis were used respectively.We study the present situation of use of garden elements(plant,water,architectural sketch),ecological technology(water saving,energy saving,waste disposal,ecological bank design,garden road).Main findings:(1)plant:Fenhe Park,a total of 136 species of terrestrial plants belonging to 50 families,74 genera,accounting for Shanxi Province,the existing landscaping tree species of 38%,69%,47%,of which the local plant species ratio was about 50%,the number ratio between the amount of 42.91%and 74.84%.There are 69 species of plants planted in Xiaohe Wetland Park,belonging to 36 families and 56 genera,accounting for 19.4%,50%and 35%of garden trees in Shanxi.The proportion of native trees is generally between 56%and 65%.The average abundance index in the Xiaohe Wetland Park was 5.1,the Shannon-Wienner index averaged 0.3464,and the evenness index averaged 0.2187.The 64 species of the terrestrial plants of Changyuan River belong to 32 families and 55 genera,accounting for 18%of the landscaping tree species in Shanxi,44.4%and 34.6%,and the proportion of native plant species is about 59%.The average richness index in the Changyuan River Park is 7.2,the average Shannon-Wienner index is 1.4326,and the evenness index is 0.7327.(2)Water:In the water supply,the selected sample can do rainwater collection,the water is not used,but as a direct discharge of waste water;part of the river to build cement hardened embankment,but the proportion of natural ecological bank;aquatic plants are grown in water,but not quite able to water plants,floating plants,floating plants and submerged plants with planting,due to the special nature of the northern climate,aquatic plants application has been limited.(3)In the architectural sketches,the use of natural materials in the garden architecture is not much.In the application of ecological energy-saving technology,the use of new energy sources,waste recycling less.Roads,plots in addition to the most advanced Road are eco-permeable pavement.(4)Landscape pattern analysis:Fenhe Park two water and green ratio is roughly equal,two of the water than the first phase of the high degree of water fragmentation,the overall shape is more complex.The spatial patterns of green patches and landscapes in the two phases are relatively complex and the degree of fragmentation is relatively high,which is strongly influenced by human activities,but the connectivity between plaques is better.The area of greening is higher than that of green area,and the maximum patch area of water body is larger than that of greening.The edge of water body is more complicated than green space,and the density of water patches is larger than that of green patches,The degree of fragmentation is higher;the shape index of greening is larger than that of water body,which indicates that the green patches are more discrete than the water patches.
