The Parks around Hefei city are a bunch of mosaic in the city center "Emerald Pearl" With social progress and development of the city, the city’s ecological environment has become increasingly important. Investigation and analysis, to understand the status of plant landscape of the park around the formation of the landscape of scientific, rational, and beautiful plants through improved gradually, and this plays an important role in improving the the Hefei ecological environment, city image.In this study, The Parks around Hefei city as a research object, the scope of six scenic spots, including Hupo、Xishan、Yinhe、Baohe、Huandong、Huanbei. From the theory of landscape ecology, landscape aesthetics, humanities, geography, and other plant communities as the basic unit, random set of plots equidistant set the kind of band’s combination of approaches, select the4800m2plot to plant Community research methods on the community composition of samples, the number of characteristics, species diversity, to investigate and take photographs. Plant communities of The Parks around Hefei city in the landscape on the basis of comprehensive and detailed survey and statistical analysis, analysis of the48communities around the city park of plant species and groups, surveys and make up the park around6scenic, but also the use of the Analytic Hierarchy Process (AHP) to evaluate the ecological functions of the park around scenic, scenic beauty, as well as social benefits, and proposed Landscape in the recommendations.The main contents as follows are:(1)In the park around the plant configuration status quo, through investigation and statistical analysis, a total of72kinds of The Parks around Hefei city community quadrat of trees and shrubs, belonging to37families,50genera, including50kinds of trees,33kinds of shrubs. The plant communities of plants constitute a park around the dominant families Rosaceae, Pinaceae, Sapindaceae, Salicaceae, Ulmaceae. Most of the tree’s diameter at breast height0-20cm range. Good plant health level, unhealthy and only8%. And made the rank of Joe, bush important value. Also calculated the layer of trees, bushes, Simpson index, Shannon-Weiner index and Pielou evenness index were:0.9607、3.4496、0.8818and0.8619、2.4388、0.7037.(2) In48quadrat plant communities, through investigation and statistical analysis, the plant density of quadrats mostly between10-19and5-9plants/100square meters, the share of communities, respectively18and19, accounted for37.5%and39.6%respectively. Average tree diameter at breast height of39distribution between0-20cm, accounting for81.3%of the total number of48communities. The arbor height of the average concentration distribution of5-10m range, and29communities accounted for2.63%of the total,6.25%,10.42%,60.42%and20.28%. Each of the communities was0.4to0.9,35accounting for72.9%of the total. (3)The Analytic Hierarchy Process (AHP) on six scenic landscape evaluation:Calculated results using the method of data analysis in the study of ecological functions of plant landscape:park six scenic Joe, shrubs, evergreen and deciduous, respectively Hupo areas (1:4,1:12),Xishan area (6:5,7:5), Yinhe scenic (5:4,8:29), Baohe scenic (4:3,20:7),Huandong scenic (1:3,11:13), Huanbei area (1:3,23:1).6scenic density between40-80plants in800m2, which amber highest,76/800square meters. The Xishan minimum43in800m2. The average diameter at breast height of trees between11-22cm, Xishan is21.31cm, the other five scenic spots are about11-14cm, very different. Six scenic trees average height of between6.2-9.5m. The scenic tree layer diversity index, Hupo, Xishan, Yinhe, Baohe,Huandong, Huanbei,6scenics’tree species richness average (S), Simpson index (D), Shannon-Weiner index (H’) and the Pielou evenness index (E), respectively2.125、0.8933、2.3992、0.8468;2,0.8981、2.4450、2.445;1.625、0.7927、1.997、0.7786;2.375、0.9147、2.5747、0.8744;2.25、0.9016、2.4554,0.8495;2.25、0.9404、2.6797、0.9271. The shrub layer is also made.In the aesthetic characteristics of the study of plant landscape and social aspects, corresponding by20professionals,50students and50non-professional students play the scenic slides were evaluated and given scores. Statistical scores and multiplied by each weight, and ultimately come to the scenic evaluation followed by scores from high to low, respectively, the Xishan area (3.6871), the Baohe scenic (3.1796), Hupo areas (3.0964), Huandong area (3.0762),Huanbei Scenic (3.0432) the Yinhe scenic (2.6687). Xishan scenic evaluation optimal, mainly due to the many tall trees, giving a certain momentum, after the transformation of2011around the city park in Hefei, increasing the number of flowering shrubs, add a lot of color for the area, and around the sculpture with more harmony, an increase of interest, giving to create a comfortable environment. At the same time a large number of Autumn Leaf species, scenic quarter phase color changes. Xishan scenic shrubs and grass community type is a significant increase in the scenic area rich in plant community structure and plant richness, plant diversity.Finally, the inadequacies of The Parks around Hefei city botanical landscape some suggestions and put forward some constructive optimization program from the ecological, cultural, artistic, suitability of plant landscape optimization, key recommendation:to promote the application of native tree species, and increase flowering shrubs, land application, optimization of evergreen and deciduous plant structure, optimize the structure of the proportion of shrubs and grass vine. And around the city park’s botanical landscape features and management optimization are given the initial proposal.
