Study On Green Volume Planning Of Wuhan Comprehensive Park Based On Recreational Behavior

With the gradually increase of the level of urban construction and the density of population,the value of Living Vegetation Volume is used to reflect the amount of leaf area per unit area.The methods including choosing the plants whose leaf area index are higher than others and improving the composition of plant community are used,to a certain extent,in order to improve the ecological level of urban green space,enhance the holistic ecological benefits,and provide quantitative guidance for urban construction and green space planning.However,regardless of the direct vector-vegetation type,the different communities of different types of vegetation,or the different activity space constructed by the plant community.In the premise of meeting the corresponding ecological benefits,the most widely used users still be human.Therefore,this paper takes the three-dimensional green quantity as the basic starting point,taking Wuhan City Zhongshan Park,Jiefang Park and Qingshan Park as the research object,combined with large data analysis method and combined with a large number of questionnaire survey,study the human recreation behavior in the park and the relationship between the green quantity and recreational behavior.Based on the evaluation of the satisfaction degree of the green quantity of the different activities,the index system and the corresponding model of the green quantity of the urban integrated park and the green quantity of the activity space are determined.And hoping to provide some guidance for the planning and design of urban integrated parks,and to provide research methods and related reference for the development of urban green open space index system.The main research process and conclusions are as follows:（1）Based on the measurement of the green quantity and the corresponding remote sensing image,the NDVI-LAI inversion equation is fitted with Y=2.001x^0.879,and the present status of the Zhongshan Park,the Jiefang park and the Qingshan Park is measured happening.The overall green quantity,Qingshan Park>Jiefang Park>Zhongshan Park,the functional partition of green quantity comparison,quiet resort area>children’s activities area>cultural and entertainment area>garden management area>service facilities area.（2）Based on the acquisition of large data and the way of traditional questionnaire survey,the analysis of urban integrated park recreation behavior is carried out.The research contents include the content of the crowd,such as the aggregation preference,the basic information characteristics,the recreational behavior characteristics,the distribution characteristics of the activities,and so on.The proportion of male and female is relatively balanced,the age level has the trend of differentiation of middle-aged and retired elderly.The distribution of various activities is fragmented,and the service facilities in the park have the benefit of specific activities,and the distribution trend of the population is Quiet resort area>cultural and entertainment area>service facilities area>children’s activity area>garden management area.（3）The relationship between recreational behavior and green quantity is mainly analyzed from the aspects of population distribution and activity type.There was a significant positive correlation between the distribution of the recreational population and the green quantity,and there was a significant negative correlation between the two fingers after reaching a certain amount of green.The distribution of the activity type does not take into account the influence of the service facility,and the corresponding trend distribution is carried out according to the expected green quantity of the activity.（4）With the satisfaction degree as the basic basis for constructing the index system of urban complex park,the relative green quantity range is summarized,the total green quantity of the park is between 1.7-4.2 and the average green quantity is about 3.0.For the functional area,the quiet area of the quiet area is between 1.8-3.4,the average is about2.9;for the children’s activity area,the green quantity is suggested to be from 1.4 to 4.2,the average is about 3.1;the service facilities area is between 1.3-4.3,the average is about2.7;cultural and entertainment area green quantity range of 1.8-4.0,an average of 2.9 or so;garden management area green quantity is about 1.4-4.4 and the average value of 2.9or so.Taking into account the hard and water in the park,through the regional rate of the volume rate of this indicator to add the corresponding:the park as a whole green volume rate of2.3 or so.The area green volume rate of the quiet area,the children’s activity area,the service facilities area,the cultural and entertainment area and the garden management area are fluctuating around 2.9,3.0,1.3,2.2 and 2.3 respectively.
