Research On The Plants Species Investigation And The Plant Landscape Evaluation Of The Park In An Yang

Public parks which is named the urban green lungμ, is the most important part of urban. As oneof four garden construction elements. The plant which has the high ornamental characteristics andecological benefit, has been paid more and more attention recently. The paper focused on the plantspecies and plant landscape evaluation of four typical urban parks in An Yang. Its reached thefollowing findings:1. Through research on the plant species of four parks, its found that there are225species plantsbelonging to141genera in71families. It has109species arbor,81species shrub,11species bine,8species hydrophilous,6species bamboo,10species herbage. The number of the arbor, shrubs, bine,hydrophilous, bamboo, herbage plant species accounted for the total number of investigations is48.44%,36.00%,4.89%,3.56%,2.67%,4.44%.2. Through the sufficient investigation of4parks, the paper analyses the problems of the plant speciesin An Yang, which includes the few species of plants, the unreasonable structure of plants, theunreasonable ratio of evergreen and deciduous plants, a lot of the frequency plants, the unbalancedornamental characteristic. The paper puts forward some suggestion about enriching the plant species, andrecommends some plants. The plants have the high ornamental characteristic and adapt to the environmentof An Yang.3. The paper select10evaluating indicators about landscape, recreation and ecological benefit. Andthe paper has constructed a complete evaluation system.60typical plant landscape were elected toevaluate by the Analytic Hierarchy Process. The outcome of the comprehensive evaluation index showedthat the Plant landscape quality of An Yang parks is moderately low. They have6plant landscape were onthe first grade,17plant landscape were on the second grade,20plant landscape were on the third grade,15plant landscape were on the fourth grade, and4plant landscape were on the fifth grade. The landscapequality of4parks is different. Yi Yuan park has the highest landscape quality, the second is the Huan Shuipark, the third is the People·s park, San Jiaohu Park plants landscape quality is the worst.4. It can be learned from cities with same natural environment with An Yang City to enrich plantspecies and enhance plant landscape quality, by energetically developing and applying native tree species,rationally selecting and introducing alien species, build close-to-nature man-made planting habitat which is characterized by similarity to regional natural forest in terms of species and structure, structural integrity,rich species diversity, high biomass and tendency to steady state so that plant landscape type can beenriched and plant landscape quality enhanced.
