Study On The Evaluation System Of Landscape Planting

In the dominated elements of surrounding landscapes,plants as soft materials play a important role in the respect of creating landscape effect.The researchers are evaluating present plant landscapes of garden and getting experience in order to construct highly qualified garden plant landscapes in a human way.At present,the evaluement to garden plant landscapes at home and abroad is that most of it is as one-item and at radom,which lacks of systematic analysis of the evaluating system.According to the phenomenon that there is no the systermatic evaluaement in the internal country to the garden plant landscape referenced by designers of garden plant landscape,this reserch discusses how to build the evaluated system of garden plant landscape from varous perspectives and directions.On the basis of analysis of garden plant in the internal country and landscape evaluation in related field,summing up the evaluated theory of the exist landscape,the thesis put forward the advantages and disadvantages of landscape evaluement made by diferent schools in various models.With the real feature of utility in the garden plant land scape,it suggests that the construction of evaluated sys tem in garden plant landscape must be in the support of ecology composition and environmental psychology,considering not only objective construction composed and real function but analysing the effect of human emotion in the gardenplant landscape from the anticipants of landscape——the angle of subjects in the landscape as well.The thesis conbined with the cases of garden plant landscape's construction in Harbin, Shenyang,Dalian,Beijing and Shanghai,analyzing the principle of dominant elements and form in practice in ecology,composition and psychology in garden plant landscape;introducing the concept of evaluating "scale";deviding the evaluation of ecology composition in garden plant landscape into the scale of large,middle,small;various scales of composition and function features in gaden plant landscape combined;the main contents of ecology evaluation in garden plant decided.These evaluation of garden plant landscape will be limited to the scale of moddle and small;and garden plant landscape may be sensed directly regarde as main objects in the reserch.The evaluation of garden plant landscape under the middle scale maily involves in the profit of ecology,society and econemy of entire landscale as well as external composition of landscape,etc.In term of small scale, it dominates the internal and external composition evaluation of group plant landscale.Meanwhile, the function of concrete figure and speciality of plant in the functional evaluation is considered such as wether it is age-old trees,ect.On the basis of analyzing ecology composed element in garden plant landscale,three composed theories are conbined with the cases of garden plant landscale analyzes mainly the colour composition,plane composition and space composition.The principle of beauty in form has important function in the evaluation of garden plant landscale which is experimented and proved.The main element,location,centre of landscape and sense of space which affects three-dimention structure are concluded.The theory of "multiple-dimention" in the aesthetics' evaluation of plant landscape is put forward,which The visual sense is the centre,along with the sense of hearing,the sense of smell,as well as sense of touching forms multi-dimemtion landscape space.By contrast to the ecology scale,it suggests three visual scales of farther,near and nearer,and points that the scale should be entered the small-scale of ecology scales which can be sensed directly by organs of human being.In the guiding of "well-foundedi of human way" and with the theory of psychology,the thesis analyzes creatively the process stumulated by garden plant landscape to the pschology of humanbeing,researches in from the sense humanro towards plant landscape and cognition to behavours of plant landscape perspective model and pattern model;researches how the plant landscape affects the people's emotion;definates the evaluated content of garden plant landscape; builds the "pyramid"model of psychology evaluation;the three scales of relationship between garden plant landscape and people's psychology and behaviour,that is,individual scale,social scale and public scale.It is clear that the psychology evaluation of garden plant landscape is the basic sense evaluation as well as in the scale of direct sense of human organs evaluate plant landscape.On the basis of definite evaluated content of garden plant landscape,the thesis uses the comprehensive method,main-element analyzing method and group method of index to select ecology index,composition index and psychology index respectively.By three round selection in the 130original index,35 representetive index is decided,which is made into evaluated index assemble.of garden plant landscape.By the layer analyzing method,definating the balance of each level of index,building evaluated system of index in garden plant landscape,definating 7 procesures in total of evaluated process in garden plant landscape which is from the definit characteristics of evaluaed system,the aim of evaluating,evaluating content,select and measure of evaluating index, methods of evaluating,evaluating execution to the analysis of evaluating result.The quantified model of evaluated system A=0.4077X+0.258349Y+0.333951Z.That is,the comprehensive quality of garden plant landscape A is equal to psychology element X.Aesthetics element Y and ecology element Z add to balance product of each part.The stereoscopic figure of evaluating system in the plant landscape is built up objectively and subjectively.The thesis emphasizes the neglected change of people's psychology and emotion in the previous evaluating of plant landscape,extends the evaluating content,setting up a set of evaluated index system conbined quantity with quality.This evaluating system not only acts as preevaluating design of plant landscape but as evaluating to the established plant landscaape as well;not only used by planning designers but also provide data for plant researchers.It has a stronger useful value and higher applicable prospects.
