Study On Application Of Plant's Colors In The Waterfront Of The Plant Communities In Zhengzhou

Waterfront is an important part of urban green space system,which plays an important role in improving the comfort of urban living environment,and also in improving the natural environment and enhancing the image of the city.Plant landscape is the most important elements of the landscape in waterfront area,which determines the environment atmosphere and artistic appeal.This study choosing 45 waterfront plant communities as the research objects in the 7 parks:Zhengzhou Zijingshan Park,Digital Park,People's Park,Botanical Garden,Sculpture Park,Wetland Park and The Forest of Zhengzhou.And reference to the change of temperature in Zhengzhou in 2015,based on the comprehensive survey about the 45 plant communities,researching the phenology and analysing the approachability of the seasonal phenology ornamental characteristics of the plant communities,and come to a conclusion of the most abundant ornamental period of the colors of each community.And using the RHS Color Chart and the Canon S60 camera and other tools to collection the different ornamental colors datas of the plant.communities in different phenological phase.In this paper,making the waterfront plant commounities colors of Zhengzhou city parks as starting point,researching the application of plant communities in colors.And puts forward the problems and suggestions for optimization about the colors application of the waterfront plant communities and the selection of the species of the plant communities in Zhengzhou city parks,in order to explore the construction of Zhengzhou city color.Through the data collection and research,the following main conclusions are drawn:(1)All the year round in Zhengzhou,the spring and autumn season is short,summer and winter is longer,which is only 54 days in spring,132 days in summer,62 days in autumn,117 days in winter.The phenology color statistics in the plant communities are most colorful in spring,the there are leaf changing in autumn and fruit trees in winter,the proportion of green plants are too large in summer,the branches' colors of evergreen and deciduous trees are too large in winter.Therefore,the richness of color is uneven during the four seasons,the plant species selection and plant color application still needed to be improved in summer and winter.(2)The plant species selected in the waterfront of the plant communities,there are 26 plant communities are aquatic and hydrophilic plant communties.And it has 15 plant specieses among the 120 plant specieses which are selented as the research objects.This shows that the construction of the waterfront plant communities are in infancy in Zhengzhou,and it's thoughtless about the relations between the three of that community building and the size and the situation of the water,(3)There are 9 patterns of the plant communities in waterfront of Zhengzhou parks:trees+shrubs+grass,trees+grass,shrubs+grass,trees+shrubs,single trees,trees+shrubs+grass+aquatics,trees+shrubs+aquatics,trees+aquatics,trees+grass+aquatics,the growing conditions of the plant communities are in general state.(4)The color ornamental characteristics of the plant communities in different seasons to meet,the temperature had the greatest influence on the phenophase,the proportion of spring flowering plant species accounted for all flowering species more than half.(5)Collecting the colors dynamic datas of the single plant,it comes to a conclusion of the RHS numbers of flower colors,leaf colors,fruit colors,branches colors in different phenological periods about the 120 plant species.And it to lay the foundation of establishing the colors datas and the digital landscape about the plants in waterfront of Zhengzhou and also the colors of the city.Through the study of this subject,based on the investigation of the structure and the colors about the plant communities of the waterfront in Zhengzhou,researching the structure model with the colors about the plant communities in the waterfront in Zhengzhou parks,and collecting the dynamic datas about the colors of the plants,and providing certain theoretical basis and data support for the application of the colors about the plant landscape in waterfront of Zhengzhou.And it can be helpiful to the quantitative research and the application of plant color theory,and providing the technical support for the construction of the colors in Zhengzhou.
