Evaluation Of Ornamental Bamboo Landscape Based On Visual Features

As one of the important elements of the urban green space to ornamental bamboo,it not only can improve the urban green space environment,but also can have fun,give a feeling of beauty for person,and it has an important influence for the human body's psychology.But it is the specific impact by different ornamental characteristics of bamboo landscape of human physiology and ignore there is still no explanation of the system.For scientific quantitative evaluation of different ornamental characteristics of bamboo landscape impact on people's physical and mental,as the urban living environment provides the theory basis for the use of bamboo plants,Based on the on-the-spot investigation research and literature reading,on the basis of the evaluation system of ornamental bamboo landscape was presented in this paper,With 108 different kinds of common ornamental characteristics of bamboo landscape as the research object,Using biofeedback method and psychological questionnaire test method,and analyzes the different ornamental characteristics of bamboo landscape of different gender college students physical(eeg,blood pressure,pulse)and psychological(mood state,state anxiety).On this basis,put forward according to different gender groups of different ornamental characteristics of bamboo landscape application strategy.The main research results are as follows:(1)As the starting point to the viewer's point of view,A classification system of ornamental bamboo landscape based on stalk leaf and color ornamental characteristics was proposed and established(four categories,nine small class),that the bamboo landscape type of stem's color(it's green of stem that amboo landscape,it's kind of monochrome of stem that bamboo landscape and it's kind of colour of stem that bamboo landscape),stem type of bamboo landscape(stem section morphology change type of bamboo landscape and shape variation of culm internodes type of bamboo landscape),leaf colour type of bamboo landscape(leaf green type of bamboo landscape and combination of leaf colour type of bamboo landscape),leaf type of bamboo landscape(leaves's small type of bamboo landscape and leaves's large type of bamboo landscape).(2)In the aspect of physiological evaluation:Under the urban environment visual stimulation,the high alpha brain waves of people were reduceand,Systolic blood pressure(1.21 2.96 mmHg),diastolic blood pressure(1.00 2.37 mmHg)and pulse(0.53-1.28 stroke per minute)values are increased,the high beta brain waves of people were increase,and systolic pressure,diastolic pressure and pulse value was rise;This shows that the different ornamental characteristics of bamboo landscape visual stimulation is better than the urban environment can effectively relieve tension and stress.While the different visual characteristics of bamboo landscape visual stimulation is the subjects showed a positive physiological response,Including high reduce alpha increase and high beta,systolic blood pressure(5.13-10.79 mmHg),diastolic blood pressure(0.61-6.37 mmHg)and pulse(0.79-3.66stroke per minute)value decreased.The results indicated that the visual stimulus of different ornamental features could alleviate the tension and stress more effectively than the urban environment,so that the subjects were in a relatively calm and relaxed state.Four categories of ornamental bamboo landscape,stem color bamboo landscape and stem type bamboo landscape of subjects physiological effect is relatively obvious,the leaf color bamboo landscape and leaf type has little effect on bamboo landscape.Nine little kind of ornamental bamboo landscape,stem green bamboo landscape,stalk monochrome bamboo landscape,stem color combination types of bamboo landscape has obvious impact on people's physiological function,and the combination of leaf color bamboo landscape and leaves small bamboo landscape to the human body physiological effect is small.And women more sensitive to the landscape environment awareness.(3)In the aspects of psychological evaluation:after watching city environment photos,anger value(0.64 1.13),fatigue(0.13-0.73)and negative emotion value(1.07-2.20)higher degree,positive emotional value(0.79-1.33)and decline in energy level(0.93-2.63);And ornamental characteristics of bamboo landscape visual stimulation on subjects of psychological had a beneficial effect,reduce the anger value(0.30 1.18),fatigue(0.47-1.90)and degree of negative emotions(1.13-2.73)and increase the positive emotion value(0.70-2.37)and energy level(0.37-1.9).Four categories of ornamental bamboo landscape,stem color bamboo landscape and stem type bamboo landscape of the subjects psychological impact is more obvious,followed by the leaf color kind of bamboo landscape,with minimum bamboo landscape effects of the class.Nine little kind of ornamental bamboo landscape,stem green bamboo landscape,stem color bamboo landscape,the shape variation of culm internodes bamboo landscape has obvious effect to the person's psychology,and leafy green bamboo landscape,leaf color combination types of bamboo landscape,leaves small bamboo landscape and leaves large bamboo landscape psychological effects on the human body is very small.And the impact on women than men.(4)According to the results,the paper puts forward the following application of ornamental bamboo landscape strategy:For overall urban residents,it can increase the application proportion of stem color bamboo landscape,stem type bamboo landscape,stem green bamboo landscape,stalk monochrome,stem combination color bamboo bamboo landscape landscape,culm internodes morphology changes in the application of bamboo landscape proportion;For different gender groups,the female tourists for the green space system planning,highlight the different ornamental characteristics of bamboo landscape environment of the visual stimulus.
