Based On The Close-to-nature Landscape Architecture Of Shenyang City Park Plant Disposition

With the development of social productivity,industrialization,urbanization,marketization process continues to accelerate,bringing economic,and social development,but also result in deteriorating ecological environment.Important part of urban parkland as urban complex ecosystem in creating beautiful living environment,improve the quality of the urban environment plays an important role.Near natural garden philosophy emphasizes humanity to respect nature,according to the laws of nature to build the garden,in order to meet present and future generations the ecological benefits of green space,the demand landscape benefits,social and economic benefits,therefore,is to promote the city near the natural garden one effective way to sustainable development.In this paper,this paper Shenyang nine of the 18 city parks with people plant community conducted a survey to study the flora survey of plant community composition,community characteristics of community types,community structure,species diversity.Based on the research of nearly natural garden concept and connotation,according garden,forest ecology,urban ecology,landscape ecology,restoration ecology and ecological aesthetics basic theory and other related disciplines,while referring to recent natural forestry,Miyawaki Zhao afforestation law and related methods,nearly natural stream restoration and management,presented the principles and methods to create a near-natural garden green communities;and analysis applications and AHP evaluation index system was constructed near natural garden green communities,and to evaluate applied to the evaluation index system of green space in Shenyang City,the last of the existing plant community based on the author's transformation strategy Shenyang city park 18 classification of plant communities to be transformed.The main conclusions are as follows:1)Evaluation results of the evaluation index system of natural garden green communities near idealAnalytic Hierarchy Process evaluation index system was constructed near natural garden green communities.From the naturalness and landscape aesthetics index of plant communities both in plant community composition,a comprehensive evaluation of the ecological level indicators from four aspects of plant diversity,community stability,and plant health degree,community composition and other characteristics,landscape-level indicators from the color seasonal,ornamental characteristics of three aspects,psychological evaluation,a comprehensive evaluation.Construction of the plant community near natural green space evaluation index system to evaluate and determine the grade.Shenyang city green space for the study,the evaluation index system nearly natural garden green communities applied to the evaluation of Shenyang garden green communities,the 18 plots evaluation scores between 0.021?0.078,scoring more concentrated in three four.Near natural garden green communities comprehensive evaluation results in line with the actual situation,its application and evaluation results more satisfactory,indicating that the model is workable,effective and practical,can scientific,objective and true to quantify and reflect Shenyang Situation city Park garden Plant Communities,basically meet the Shenyang City parks plant community comprehensive evaluation requirements.2)Summary of Shenyang geographical characteristics suitable basic configuration methods and models of plant communities,that same family,belong to the species adapt to urban habitats,species,poor adaptability of species substitution,reconstruction and climax plant community species composition and structural characteristics similar plant community.Secondly,designed to protect and create mixed habitat diversity.By artificially creating a combination of natural development and vegetation,using simulated natural green technologies and methods,gradually cultivate near natural vegetation.Individual species at different stages of development,there are significant changes in the niche,species from germination,showing more and more narrow ecological niche,especially manifested in terms of mineral nutrients and light,in all material being studied,the seedling stage after a strong ability to adapt to habitats more mature.Shenyang parks in the form of plant communities can be configured according to community and environmental characteristics,using trees + herbaceous type,type of tree + shrub ten herbs or shrubs + herbs type.Mixed green plants take horizontal and vertical mixed way.Mixed level is through the introduction of different habits(such as shade or full sun,deep or shallow root root and shoot type,leaf type,color,etc.)species,the formation of evergreen and deciduous broad-leaved mixed forest,the author of the above summarizes several recent natural community and create mode:deep roots of plants with shallow roots&high canopy density of trees with shade-tolerant shrubs&seasonal evergreen understory plants as well as being landscape with applications for reconstruction after the recent natural communities has played a guiding role.3)According to the results of research studies and analysis of Shenyang city park,draw the merits of the value of each community,through the application of near-natural plant community transformation model,the 18 plots to transform the plots disadvantage to correct for near future transformation of natural communities play a reference role.
