Development And Research Of Modern Landscape Agriculture

"Roof Farm" is a new greening model based on roof greening combined with agricultural planting.Roof farms have been developed in Europe,North America and other countries.People use the idle roofs in the city to open up fields,grow vegetables and fruits.These actions let the people in the city experience the agricultural cultivation and the agricultural landscape.In China,the roof farm is at an emerging stage of development,the theoretical research is still at the stage of exploration,and has not formed a complete system.Based on the research issue of urban roof farms,this paper selects three roof farms for evaluation and analysis,and then based on Hefei Huaguoshan roof farm,combined with relevant indicators and operation modes,summarizes the problems existing in the farm and conducts them.Replanning Finally,taking these four roof farm cases as research objects,starting from the comprehensive quality evaluation research of urban roof farms,a set of scientific and reliable evaluation methods and index systems are discussed.The main research contents and results of this thesis are as Following:(1)An overview of the related concepts of urban rooftop farms and developments at home and abroad.(2)Analyzing the research background,significance,purpose and research methods of urban roof farms.(3)To provide some constructive references are made for the construction and promotion of the farmof Heifei,this paper selects Brooklyn Roof Farm,Nanjing Water Tour City Magic Bean Sky,Hefei Huaguoshan Roof Farm as the research object.Based on the analysis of the above research cases,combined with the operation mode of the foreign city roof farm,the redesigned design Of the Hefei Huaguoshan roof farm site,mainly from the crop selection and configuration,functional space setting,maintenance management,operation mode,etc.(4)Using the analytic hierarchy process to construct the evaluation index system,determine the weight of each evaluation index and the scoring standard,and comprehensively evaluate the roof farm through AHP-fuzzy comprehensive evaluation analysis method.The ranking from high to low is Hefei Huaguoshan roof farm.(After the transformation),the comprehensive quality is Grade ?(better),the comprehensive score of evaluation is 85.1547;the comprehensive quality of Brooklyn's roof farm is Grade ?(better),and the comprehensive score of evaluation is 84.2003 The comprehensive quality of Nanjing Shuiyoucheng Magic Bean Sky is Grade III.(General),the comprehensive score of evaluation is 77.5707;the comprehensive quality of Hefei Huaguoshan Roof Farm(before transformation)is Grade IV(poor).The comprehensive score of Evaluation is 67.8844.The evaluation indicators for the roof farm are fully quantified.
