Research On Plant Community Of Zhuzhou Road Green Space And Ecological Benefits

Plant community of road green space is an important component of urban green space and is closely linked with people’s daily life. This subject research seeks to establish an appropriate ecological design pattern so as to provide references for future ecological design of road green space system of Zhuzhou City in combination with the research model of ecological benefits and elements of plants arrangement based on comprehensive and deeply understanding of the status quo.Through the investigation for green space of118roads in Zhuzhou City, it can be known that there are various plant application species in the plant community of road green space of Zhuzhou City, which have a bright color and a strong sense of layering and change with the season. We can see the road green landscape, a total of147kinds of plants, belonging to46families and93genera. Which129species of woody plants,18kinds of herbs, shrubs,46species,83kinds of trees, shrubs and trees ratio is about1:2; from the quantitative point of view, shrubs and trees the proportion is about5:3. Total83kinds of evergreen plants,46kinds of leaves; in volume terms, the proportion of evergreen and deciduous trees of about12:5. Differences in species richness of different levels of road green landscape. Species richness descending order as follows: the trunk road species richness (15.7)> highway (13.4)> distributors (7.9)> slip (1.3); Shannon-Wiener index by descending order of the main trunk road (2.25)> distributors (2.13)> Expressway (1.89)> slip (1.21); Simpson diversity index of0.5or above, the descending order:Trunk Road (0.621)> distributors (0.604)> slip (0.553)> Expressway (0.520); Pielou evenness uniform descending order as follows:the fast road (0.96)> Trunk Road (0.87)> distributors (0.86)> slip (0.79); can be seen from the data,3a diversity index, basically was a significant positive correlation trend. Can be drawn from the survey sample data, Zhuzhou City road green landscape of plants used in variety of bright colors, layering, and showed a seasonal variation. Arbor ratio, the the camphor proportion is too large, may be appropriate to use more of the other trees in order to strengthen the rich sense of the green landscape of Zhuzhou City road, reducing its monotonicity. The ecological benefits of the selected temperature and humidity, the determination of the anion content and research. Temperature and humidity research, chose seven sample field investigation:seven of the cooling effect of the observation point:Changjiang North Road, Renmin Middle Road,> Jiangshan Road, Zhuzhou Avenue middle of> Shaoshan> Zhuzhou Avenue preceding> Young Li Lu; the humidifiers effects descending order are:Changjiang North Road, Renmin Middle Road,> Jiangshan Road, Zhuzhou Avenue middle of Zhuzhou Avenue preceding> Li Yang Road (shrubs+ground)> Shaoshan. Anion concentration is divided into geographical differences in the industrial area and non-industrial areas, select the eight observation points to carry out field investigations:air cleanliness of non-industrial areas of industrial zones, industrial parks Xiang Shan Road> copper detour> stone ring road, non-industrial Changjiang North Road, Zhuzhou Avenue middle of> Shaoshan Zhuzhou Avenue preceding> Li Yang Road; all observation points only Changjiang North Road, hit the D-level of air cleanliness standards, Zhuzhou City air quality needs to be improved. The survey shows the public road green landscape of Zhuzhou City plant configuration is quite satisfied, has been recognized by the public;40percent of the public feel that the local characteristics of Zhuzhou City road green is not well represented in the comprehensive evaluation of the green landscape of Zhuzhou City road, with local characteristics. Therefore, Zhuzhou City shall strengthen its construction of road green space and apply more plants with local characteristics, attach importance to ecological benefits of road green space, embody urban characteristics of Zhuzhou City and allocate plant community applicable to Zhuzhou City more rationally. This paper concludes and analyzes some typical plant allocation patterns of plant community of road green space in Zhuzhou City, puts forward problems existing in the application of plants in road green space of Zhuzhou City, points out what needs to be paid attention to with respect to the plants in road green space of Zhuzhou City and provides corresponding solutions.
