Studies On Plant Disposition Based On The Horticutural Therapy

With the development and improving of the process of urbanization and material living standard,plants not only provide the function of beautifying and decorating the landscape,the growing popularity of horticultural therapy makes people more aware of that the application of horticultural plants should be considered in the stage of plant landscaping.A good combination of horticultural plants makes the environment bring its own healing effect.Nowadays,the use of horticultural therapy is rarely considered in the landscape design of university campus,but,combining with horticultural therapy to create a convalescent horticultural landscape of university campus,creating a green ecological environment which beneficial to human health depends on how to choose plants reasonably.This paper is based on the new campus relocation project of Chengdu Sports University,the studies investigated current situation of different plant collocation forms in the campus based on the horticultural therapy mainly from 2 sides:the number and collocation forms of plant species.In addition,measuring the data of the influence of landscape plants on the ecological factors in the air by using THI air quality evaluation coefficient and negative oxygen ion concentration and other data to evaluate and analysis of the connection between different plant species,different plant collocation forms and human comfort.The main research results are as follows:(1)Through field survey and combined with relocation statistics.Among the landscape plants in Chengdu Sports University,65.12% are arbors,20.93% are shrubs,12.21% are herbs,and only 3 kinds are vines,accounting for 1.74%.There are many kinds of plants but they are not evenly distributed and there are too much arbors and shrubs more than herbs and vines.(2)Different plant combinations have different purification effects on temperature and humidity,increase of negative oxygen ion concentration and reduction of inhalable particles in the air.But the general rule is follows:The effect of "lawn" <The effect of "plant collocation form with herbs and shrub" <The effect of "plant collocation form with multiple shrubs" <The effect of "plant collocation form of herbs and arbors" <The effect of "the plant collocation form of arbors and shrubs" <The effect of "the plant collocation form of arbors,shrubs and herbs".The more complex the form of plant collocation,the greater the impact on eco-climate factor and the better effects.(3)Through field investigation,data acquisition and research,this paper can provide reference data for campus to use horticultural therapy combined with landscape plants.Finally,combined with color therapy and aromatherapy,some suggestions are put forward for the selection of plants in the campus.
