| With the gradual deterioration of urban living environment, public pay more attention to the wetland and other natural ecological system. Developing and constructing the wetland park, it’s beneficial to give full play to a variety of functional benefits of wetland habitat and highlight the value of ecological services, at the same time, meeting the requirements of social economic development and the demand of public tourism. At present, under the pressure of living in high tension city life, the demand of wetland tourism grows day by day, and the wetland park is becoming one of the most important place of recreation and entertainment for tourists, but also brings a lot of problems. The conception and thinking of landscape system planning and designing is far away from the tourists’ actual needs. How to evaluate the social value in the wetland ecosystem services, and which social services are more preferred. All this requires to seek new research methods and techniques for further exploration and understanding. The traditional methods of investigating the landscape preference and travel behavior mainly rely on questionnaire survey and face-to-face interview. There are some shortcomings in these methods, the authenticity and validity of data is worth further discussion. This paper based on the research of the review at home and abroad about landscape preference and travel behavior, taking pictures and positioning by the smart phone, to combine the method of VEP (Visitor Employed Photograph) and GVT (GPS Visitor Tracking) to study the research. This paper selected WuSong Paotaiwan wetland forest park as the research area, and recruited 32 travel volunteers. The volunteers took 1212 pictures contain all kinds of scenery totally, to further discuss the tourists’ perception of landscape preference and behavioral expression. The results of landscape preference show that:The highest frequency of the first three kinds of landscape type are water body, vegetation and pedestrian system. The travel volunteers have a high preference for the main landscape type in the park. The boardwalk walking system and brick art facilities are the most attractive points nearby river wetland, and the female volunteers’ preference is higher than male on the pedestrian system. The calculation of Kernel Density Estimation and the spatial analysis of the photo shoot position, it reflects that travel volunteers’ dense areas are Kuangkeng garden, Wusong Fort Memorial square and viewing platform nearby-river wetland. The special green water in Kuangkeng garden, the strong historical and cultural value in Fort Memorial square and the open field of vision in viewing platform nearby-river wetland, all of these have a strong appeal to the travel volunteers.Recently, public and government pay more attention to the assessment of the value of the wetland park, traditional ecosystem service function value assessment practices are mostly based on economics, monetary mode, which few consideration of the social value attribute and spatial heterogeneity. Especially to the users’ feeling evaluate. In one part, traditional wetland park construction and planning mostly based on the suggestion of managers and constructors, which lacks taking the users’ opinions into consideration, and there is no ecological value protection system based on users. In another part, how to involve the methods of studying travel behavior and landscape preference into evaluation of the social value of the ecological service function is the focus of this paper. Based on the subjective preference of tourists, using the volunteers’ photo shot positions replace the map labeling In traditional questionnaire investigation. Taking the model of SolVES (Social Values for Ecosystem Services) into it to explore the differences of tourists’ perception of different social value for the wetland. It improves this model’s data source acquisition and tests its feasibility in application of small scale area. According to previous literature research and the characteristics of Wetland Park, choosing 7 kinds of ecological service values as the research objects. Aesthetic value, Life sustaining value, Historic cultural value, Biodiversity value, Learning value, Spiritual entertainment value and Therapeutic value. The result reflects: travel volunteers showed a high degree of preference for the park’s aesthetic, spiritual entertainment, biodiversity and life sustaining value, the historic cultural value and learning value is a little lower, maybe it response to its few distribution area. Aesthetic value has a strong negative correlation with the DTW (Distance to Water), the aesthetic value in the 20m range is generally higher, which reflects travel volunteers pay more attention to the hydrophilic experience. Life sustaining value and biodiversity value has negative correlation with the DTWL (Distance to Wetland), the farther away from the wetland, the lower the value is. There is no significant difference on aesthetic value assessment between the male and the female. The male’s higher spiritual entertainment value distribution areas are bigger than that of female, and the Life sustaining value and the biodiversity value in the area of wetland is generally higher than that of female. In view of the fact that the value of historic cultural and learning is lower, the park need to enlarge the propaganda and education to highlight and develop the cultural value of the Wetland Park.Getting pictures from dianping.com is a supplement for VEP, to describe the park’s state of development and the tourists’ seasonal variation. Besides, based on more than 2000 tourist comments on Wusong Paotaiwan wetland forest park from the website of www.dianping.com, using ground theory, a technique of qualitative studies to analyze and summarize. Constructed a conceptual model including five dimensions of travelling expectation, travelling behavior, core landscape, service facility and evaluation after the tour, to deep understand the tourists’ motivation and experience. Through statistical analysis and summarize, key words of tourism behavior mainly for play, photography, walking fitness, etc. Travel experience feelings mainly for positive attitude. From these key words, we can conclude that the park positioning and know the park’s image in the public mind. There are a lot of advantages to evaluate the public’s satisfaction through social comment website. One is which can get more data easily, another is the comments’ higher authenticity. Because in this stage, people initiative to make comments, which can speak freely, no other interference factors. So it can fully understand the status of wetland Forest Park in the public’s eyes and park positioning. The analysis show that the differences of visitors to the wetland park’s seasonal landscape are more obvious, and the tourists are more prefer to autumn park scenery. The most satisfy the tourists is mainly to experience the wild nature, walking fitness, the main problem is lack of food facilities and parking lots. So the park’s planning and construction need to consider the tourists’ subjective preference and public’s problems, so that to meet the immediate needs of tourists and enhance play the experience.This paper provides a research method of relying on science and technology and social networking platform, it just a beginning. In the following research, the methodology for the collection and analysis of such data can be applied into many aspects, which has a strong practical value and prospect. In the future studies, with the application of big data and the rapid development of intelligent App, data collection and analysis can rely on these technologies. Combing quantitative and qualitative methods to study the preference data and pay attention to the public preference, in order to promote the protection and the sustainable development of wetland forest park. |
