Study On Environmental Perception Of Shanghai Park

Now, city is increasingly urban. There are environmental pollution destruction of ecosystems and other problems of city we have to face. Mostly because of unreasonable landscape pattern caused by coordination between the various elements in the city, thus weakened the ecological, economic and social function of city landscape. The park is a vital part of the urban landscape ecological pattern. There are important significance to alleviate the city environmental pollution and ecological destruction, improve the city landscape ecology. The study on Environment-aware in the park is more and more urgent. This paper will focus on Shanghai parks Environment-aware studying, and then let us know what the park that easier accepted by the public.In this paper, we will take Binjiang Forest Park, Sheshan national Forest Park, Gongqin Forest Park, Shanghai Yanzhong Park, Haiwan Forest Park and Binhai Forest Park in the city of shanghai as examples, first we will get 48 photos in the parks, and then we can choose some photos as landscape photos. The photos that we choose not only represent all the characteristics of scenery in the park, but also can contain all the evaluation factors. We can combined with the field and indoor questionnaire evaluation, so we will get scenic beauty of the photos, then extract the elements of landscape and determine the value of landscape elements, afterwards to establish the mathematical model between the observation value of landscape scenic beauty and the value of each factor is determined. At last we will calculated for each park scenic beauty value through the mathematical model.For field inspection, to determine the boundary of patches based on the CAD drawings and Google Earth maps of the park. Through the Autocad software, we can extract the patch area, perimeter and so on. Then we want to determine the various parameters of landscape pattern through theory and method of landscape pattern in landscape ecology. At last we will determine the various parameters of landscape pattern.We monitored in the negative oxygen ion in the 6 parks in Shanghai city during the period from November 20, 2013 to December 15 th. We can compute the average value of negative oxygen ion concentration of 10 minutes. And the time is from 10 am to 4 pm in the autumn day. Monitoring sites are the same, just like side or in the forest trees. Many literatures have shown negative oxygen ion concentration is related to ecological land location and meteorological factors.The detection of negative oxygen ion all in the autumn get. However, through the literature we will know the negative oxygen ion is not the same in different seasons. So will get the summer data form the Shanghai Research Institute of Environmental Science and the monitoring sites, then we will calculate the average value.Then will studied the correlation between the scenic beauty of Shanghai Parks and landscape pattern, and also analyze the correlation between the scenic beauty of Shanghai parks and Negative oxygen ion. By graphing the results,we will get the data.We can see the landscape pattern and the negative oxygen ion influence on the park.There is a peak that the park landscape fragmentation index influence on scenic beauty. More or less than the peak,the scenic beauty will becomes lower.The landscape diversity is higher, the scenic beauty will be higher.We can know the corridor density index also has a peak. If we want the highest scenic beauty, we must find the most suitable corridor density.The negative oxygen ion is proportionate to the scenic beauty. That is to say the negative oxygen ion is higher, the scenic beauty will be higher in a certain range.
