2, data analysis
2.1, yanzhong usage analysis
Users in the use of frequency, one once and 3-7 days at a time, each accounted for about 40%. This shows that stays in the Green, many people have a relatively fixed frequencies, suggesting yanzhong single, does not have the diversity of actors. Through the survey found that many people under investigation are not far from green residents.
In the residence time of the survey, we found that in 16-30 minutes maximum, while more than 30 minutes for the second, least is 6-15 minutes. According to the average person walking speed and yanzhong main tour route length of relationship, you can partially explain lack of attraction for a long time in the Green, leading visitors to stay generally not long.
Users engaged in the activities of the survey found that the highest proportion of the scenery, approximately 80%; rest of about 60%. This is due to the deterioration of the urban environment and resulting from the highly stressful pace of life, at the same time reflects the delay in the green area in the context of the region’s main function is to rest and to enjoy.
2.2, the analysis of landscape elements

⑻ for around of building, sometimes note and often note of all accounted for 38%, and think around building some taste of proportion Supreme, accounted for 54%. This description surrounding of building for extended in the green of effect larger, from another angle description has extended in the green of made King manipulation insufficient to elimination surrounding building on internal visitors of effect, thus effect has extended in the green of natural of of feel.
2.2.3, comprehensive analysis
⑴ General analysis
The degree of attention and interest of each is divided into 3 grades and given weight, that the formula for calculation of the degree of attention and interest.
Note the formula: N=n1x1+n2x2+n3x3
(N1 little attention, sometimes note N2, N3 often note)
Taste of a formula: I=i1x1+i2x2+i3x3
(I1 no taste, i2 some taste, i3 great taste)
Through calculation, came results, in extended in the green of various landscape element of note of and taste of in the, natural landscape element than artificial landscape element General more by welcomes, which Woods is most by welcomes of landscape element, spent, and grass, and water, also are is is by welcomes of landscape element, and fountain this a and natural landscape element comparison near of artificial landscape element more by welcomes, this description has mass on natural of degree high of landscape element of preference.
⑵ the margin analysis
In General, the relationship between degree of attention and interest is positive, the difference between them (N-I) reflects the potential of popular landscape elements. General note values of higher value than taste. When the difference is the larger of the two descriptions of the landscape elements with greater promotion potential, needs to be improved.
Previous statistics instead, artificial landscape elements of the margin larger, which illustrates the yanzhong artificial landscape elements with greater promotion potential, through the design and improvement of further increases their appeal, so as to enhance the popularity of Greenland as a whole.
Trash-difference maximum, this shows that in yanzhong trash could be improved. Followed by leaves, this shows that yanzhong is not designed to take full advantage of this dynamic landscape. Worthy of note is the water the landscape elements of the margin is a negative number, description of yanzhong landscape elements, water attraction was the biggest play of yanzhong highlights, through advocacy, lighting, further increasing its attention.
