Research On Urban Park Landscape Elements And Optimization Strategies That Affect Emotions

Social development has brought people rich material life or social resources,but also brought high-intensity and overloaded work pressure.If the high-pressure work and living conditions cannot be relieved in time,people’s depressed negative emotions will gradually be amplified and mental pressure will be increased,leading to mental sub-health and even mental illness.The construction of urban parks in China is in full swing,and the existence of urban parks can meet people’s public health needs;as the main place of activity to get close to nature,viewing natural landscapes or performing activities in urban parks has an impact on people’s emotions.People relax their minds and bodies in the park.City parks have potential emotional regulation effects.With the development of science and technology,the application of big data technology has also provided new ways and new ideas for the study of urban parks and emotions.Existing studies have not yet fully analyzed the relationship between the environment and emotions of established parks.They are only validating and exploratory studies on emotions based on the health benefits of green spaces.Studies on emotions and urban park landscapes based on web text data need to be supplemented.,Taking emotions as the main body of research,researching urban park landscape elements can provide new ideas and suggestions for urban park construction and transformation optimization.The research takes Caijia Central Forest Park,Central Park,Bijin Park,Flower Garden,Hong’en Temple Forest Park and Eling Park as the research objects in six urban parks in the main urban area of Chongqing.Use crawler tools to crawl and sample the park’s comments and related information to obtain 7062 basic data.Use crawler tools to crawl and sample the park’s comments and related information to obtain basic data.Use content analysis,sentiment analysis,word frequency analysis and sentiment analysis techniques,text analysis and field research,and comprehensive literature review to screen out the emotional impact of urban parks.There are a total of 20 indicators including natural landscape elements,artificial landscape elements,and psychological characteristics.The positive and negative sentiment scale(PANAS scale)and the questionnaire on the use of parks are used to collect data(valid data 260 copies)for statistical analysis and exploration.The relationship between urban park landscape components and emotions,and the importance of the impact of landscape elements on emotions is clarified.The research mainly draws the following conclusions:(1)Based on the analysis of people’s overall satisfaction,emotional distribution,sources,and behavioral activities and landscape element preferences under positive emotions,it is found that people’s scores of all parks are above 4,showing a general state of satisfaction,and the landscape and facilities of all parks can meet people’s needs;In the park,people’s emotional state is mainly positive emotion,and the proportion of positive emotion is more than 88%,which is much higher than that of negative emotion;In terms of emotional distribution and tendency sources,positive emotional evaluation mainly focused on high greening rate,beautiful scenery,convenient transportation and so on,while negative emotional text evaluation focused on old and short supporting service facilities,improper management and so on;Landscape elements(including plants,lawns,buildings,etc.),behavioral activities,weather and climate,park location and transportation,park service facilities,health conditions and other factors affect people’s leisure mood in the park to varying degrees.(2)The questionnaire survey also found that people generally believe that the park landscape elements can improve their emotions.The average values of positive emotions are more than 3.0,and the average values of negative emotions are less than2.0.People show positive psychological and emotional states in each park;In terms of park use and basic information,educational background(P = 0.036 < 0.05)had significant difference in improving mood.(3)Through the correlation analysis of emotion and landscape elements,it is found that each landscape element has a significant impact on emotion;The positive emotion and negative emotion were taken as dependent variables respectively,and the landscape elements of urban park were taken as independent variables for stepwise regression analysis.The most relevant landscape factors were obtained: spatial privacy(regression coefficient value 1.841),water participation(regression coefficient value 1.623),topographic relief(regression coefficient value 2.234),and water quality The results showed that the richness of plant landscape level(regression coefficient 1.486)and the abundance of street lamps(regression coefficient 1.003)had significant positive effects on positive emotion;There was a significant negative correlation between negative emotion and strong water participation(regression coefficient-1.771),strong spatial privacy(regression coefficient-1.992),clear guiding system(regression coefficient-1.991),undulating terrain(regression coefficient-1.635)and sufficient rest facilities(regression coefficient-1.582).Based on the results,the paper studies the commonness of comprehensive parks,and puts forward the optimization design principles of humanization,attraction,participation and diversity,as well as the optimization design strategies of urban parks based on emotional influence and emotional guidance,such as choosing high quality positive landscape elements,reasonably dividing functional activity space,and planning emotional guidance dynamic tour line.
