Research On The Construction Of Bio-Diversity In Urban-Type Tourist Agricultural Garden

During the process of urbanization, different environment problems keep disturbing the people in the city continuously. Especially in the metropolises, which have a high level of urbanization, people's desire of touching the nature keeps increasing. And because of the rapid pace of life, urban inhabitants need the short-term excursion rather than long-term journey. As a result, people begin to pay more attention on urban-type tourist agriculture, which can satisfy this kind of need. Some experts have carried out researches on the relevant contents, and the planning of urban-type tourist agriculture is one of the hot points of research. However, the current researches mostly keep focus on the aspect of economic benefits, but ignoring the ecological aspect.On the basis of the reasons mentioned above, this paper suggests people introduce the method of bio-diversity construction when making the planning of urban-type Tourist Agricultural Garden. Moreover, this paper studies the method of bio-diversity construction in urban-type Tourist Agricultural Garden. The main contents and conclusions are listed as follows:(1)Defining the functions of bio-diversityThere is always a debate on the functions of bio-diversity in the stability and function of the eco-systems. Through the study of the previous research results, this paper concludes that the increase in biodiversity Is in favor of the stability and function of eco-systems when under a certain level.(2)The method of bio-diversity construction in urban-type Tourist Agricultural GardenThe method is made up of three steps: collection and analysis of basic data, goal setting and detailed method. The first step comprises the study on the natural conditions, suitable plants for the site, the level of bio-diversity, the current land use status and the current scenery status. The goal of bio-diversity construction may contain ecology aspect, landscape aspect, culture aspect etc. The detailed method can be further divided into two parts: the adjustment of spatial layout and the selection of species.(3)Application of the method This paper takes the Guoyuan village in Pudong district as an example, and applies the method in the planning of an ecological orchard. Moreover, this paper carried out two experiments, which monitor the insect pest of the orchard, in order to verify the practicability and effectiveness of the method.
