Evaluation And Research Of City Road Plant Landscape Of Development District And Luo Gang Area In Guangzhou

City road plant landscape is the foundation of city natural environment, the people's first impression of city whole plants landscape,and also intuitively exhibit image of a city. With the Significantly improved of city image position and public aesthetic level,city road plant landscape need to advance with the times and requires constant innovation, so for the evaluation and research about city road plant landscape with higher academic value and practical significance.In this article,city road plant landscape examples as the research objects from4 grades total of 68 city roads,which include expressway, trunk road,secondary trunk road and access road of Development District and Luo gang Area in Guangzhou.After field investigation,it records specific plant species, growth conditions, planting patterns and layout characteristics of research location;evaluates and analyzes a representative group of 36 road plant landscape examples by Analytic Hierarchy Process(AHP), explores its plant diversity, landscape features and evaluation results.The main results are as follows:The survey recorded a total of 118 species of research location road landscape plants, respectively scribe91 genera and 47 families. 45 species of arbor plants(including tree-like herb), accounting for 38.1%; 31 species of shrubs plants, accounting for 26.3%;42 species of ground cover plants, accounting for 35.6%. 97 kinds of evergreen plants, accounting for 82.2%; 21 species of deciduous plants, accounting for 17.8%. 61 species of exotic plants, accounting for 51.7%, 57 species of native plants, accounting for 48.3%.On the one hand,for the frist time,the research from plant landscape position more comprehensive consults views of various experts in the industry, and then obtains evaluation indexes,and establish an appropriate evaluation system of road landscape from two aspects of qualitative(subjective) index and quantitative(objective measurement index by analytic hierarchy process(AHP), then the system is applied to the evaluation of the research in; on the other hand according to the < urban road greening planning and design specification > CJJ75-97. < urban road engineering design specification >(CJJ37-2012), the research consults specific road status of the research area,for the first time proposes that dividing evaluation samples according to types of green space to comparative. Including class 5 total group 36 plant landscapes :Separation in Traffic Green Belt Plant Landscape,Avenue Tree Green Belt Plant Landscape,Traffic Island Green Area Plant Landscape,Roadside Green Belt Plant Landscape,Slope Green Belt Plant Landscape and so on.The evaluation results indicate that the composite score range from specialists, students, non-students is very close,indicating that although the level of reviewers are different,but the Subjective difference is very small.In addition, the gap between students and experts in the evaluation of smaller, indicating that students after a few years of professional training, and gradually produced a specialist closer aesthetic appeal.Comprehensive results show: No.27 Yongshun Avenue Roadside Green Belt Plant Landscape,No.22 Xiangxue Avenue Traffic Island Green Area Plant Landscape,No.29 Kaitai Avenue Roadside Green Belt Plant Landscape are relatively good,ranking in all 36 group Road Plants Landscape The former 3,wherein No.22 Xiangxue Avenue Traffic Island Green Area Plant Landscape is the highest rating;and No.33 Kaitai Avenue Slope Green Belt Plant Landscape,No.20 Yonghe Avenue Traffic Island Green Area Plant Landscape,No.31 Yonghe Avenue Slope Green Belt Plant Landscape are relatively poor,ranking in all 36 group Road Plants Landscape countdown 3, wherein No.33 Kaitai Avenue Slope Green Belt Plant Landscape is the worst.
