| Urban agricultural park(abbreviated as agricultural park)is a kind of special ecosystem types,which locate in the interlaced urban-rural area with organic food production,Eco-efficiency and cultural value.This paper adopts the method of ecosystem services and landscape services to analyze typical agricultural parks in Beijing.Ecosystem services and landscape service researches provide new perspectives and research methods on how to balance and coordinate the multiple functions of urban agricultural parks,which construct a basis for land planning and landscape design.It can deepen the understanding of landscape service supply and demand and their influencing mechanism.Based on the field visits to more than 40 agricultural parks in Beijing,this paper has combined research findings and selected product supply,waste disposal,carbon fixation and oxygen release,conservation water supply,nutrient recycling,purification of the environment,popular science education,and leisure recreation.Then,we calculated three types of typical agricultural parks ecosystem services: civics’ gardens,leisure agricultural parks,and sightseeing picking agricultural parks.On this basis,the value of the ecosystem services and the differences in the characteristics of the remaining agricultural parks were estimated.In order to highlight cultural services such as recreation and entertainment in agricultural parks,we use landscape service research methods based on landscape structure and questionnaires to reflect the complex ecosystem function of combining natural ecosystems and landscapes.This article selects two agricultural parks with similar areas and similar locations,but with significant differences in functions within the park—Small Donkey Civics’ Garden and Elven Farm,as the case studies.We selects education value,relaxing,exercising,pursuing pastoral life,experiencing nature,social relations,and aesthetic views as seven landscape services.The supply,demand,and supply-demand assessment matrices were constructed for the two agriculture parks,by using ArcGIS to visualize the space,and analyzing the supply and demand matching of the two farms.Finally,the statistics and correlation analysis were conducted on the basicinformation of tourists and their admission,and the influence factors of landscape service preferences were obtained.We gained the following main results and conclusions:(1)Through the estimation of the ecosystems service value for 24 agriculture parks,the value of picking-type tourism garden ecosystem services is the highest.Among the various ecosystem service indicators,product supply value and leisure and entertainment value are more prominent,and the economic value of the other six ecosystem service indicators is not obvious.(2)Through the evaluation of landscape service demand and supply,the values of various landscape services for the two agricultural parks are high,while the construction area for forest land is low,and the areas with high matching of farmland supply and demand are mostly concentrated areas for tourists.The supply and demand of various landscape service indicators for the people’s farms are more concentrated,and the value of aesthetic seven view needs to be strengthened.The distribution of landscape service indicators in leisure farms is more evenly distributed,and relaxation and education need to be strengthened.(3)Through the analysis of the information of the farmer’s tourist and the preferences of landscape services,it is concluded that: education affects the value of education;in the garden of the people,age influences the value of physical exercise,and leisure farms influence the pursuit of pastoral life. |
