Development And Research Of Modern Agricultural Landscape

Livelihood issues,including lack of land and resources and food safety,exist in many cities in our country,while green lifestyle and economy,as good solutions to such problems,have shown rapid development.As an important part of “green economy”,the aquaponic system can provide green and pollution-free production methods with unique advantages,and effectively reduce environmental problems,such as waste of water resources and greenhouse gas emissions.Therefore,developing aquaponic system is an effective method to alleviate the agricultural crisis.Nowadays,large-scale aquaponic devices have been widely used through close integration with leisure agriculture,while household aquaponic devices works of small design companies or creative studios,focusing on the presentation of concepts and technological introduction and not widely commercialized.This also provides a good opportunity for the development of this object.The essay first introduced the related concepts,technical principles and domestic and foreign research cases of aquaponic;followed by an in-depth analysis of the research background,research significance,and research method goals of the project;and then proceeded from the design of home aquaponic devices for household.The aquaponic system was used for experimental applications.Finally,a symbiosis evaluation system for aquaponic was established.The evaluation index system was constructed using the analytic hierarchy process.Finally,the weights of the indicators at various levels were determined,and the index weight values were ranked.The main research contents and results of the essay are as follows:(1)Introduce relevant concepts and technical principles of aquaponic,and analyze domestic and foreign research cases.(2)Analyze the research background,significance research method and objectives of the project.(3)Divide the family-usable space into three parts: balcony,courtyard,and roof.And design aquaponic devices respectively,followed by detailed analysis.(4)Two aquaponic experiments were designed.The concentration of internal matter in the large-scale aquaponic system and the concentration of water in and out of the small-scale aquaponic system were determined.It was proved that the large-scale aquaponic system has stability and stability after design and promotion.Water purification capacity.(5)Experiments were designed to determine the effects of fish growth density on system operation,and the most appropriate fish growth density in the aquaponic device for domestic fish dishes was selected to maximize the benefits of fish and vegetables.(6)Determine the factors of aquaponic system evaluation,and using the analytic hierarchy process to construct the evaluation index system.Finally,the weights of the indicators at various levels were determined,and the index weight values were ranked.
