Research On The Logistics Distribution Layout Decision Of Precision Urban Agricultural Products Based On GIS

With the accelerated development of urbanization in our country,the urban population is increasing and the urban area is gradually expanding,but the city blocks,road planning backward,and backward logistics technology in logistics slow,high cost,serious waste,is not suitable for the modernization process,seriously affecting the residents' happiness index.As a living necessities of the residents,the supply of agricultural products directly affect the normal life of residents,its importance is self-evident.In this context,in order to realize the site selection of agricultural product logistics distribution center,agricultural logistics and distribution information platform,and so on,the paper comprehensively applied knowledge such as logistics,computer science and geographic informatics,It can provide reference for urban science and rational planning of agricultural products logistics distribution center,and technical support for agricultural products logistics and distribution information.This paper summarizes the logistics of agricultural products at home and abroad,the location of the distribution center of agricultural products,the research status of agricultural products logistics distribution informatization,analyzes the existing problems of agricultural product logistics layout,puts forward the development direction of agricultural product logistics distribution system.The paper firstly introduces the relevant theoretical knowledge,strong space on the basis of using GIS software the analysis,through the analysis of influencing factors on distribution center location based buffer overlay,implementation of agricultural products logistics distribution center selection objectively,then using analytic hierarchy process,subjectively ultimately determine the location of distribution center location.This paper introduces the design process of the Oracle database,using Java programming language,the use of Struts 2,Spring the design of Hibernate framework,and implements the agricultural product logistics information platform.Using the genetic algorithm to solve the optimal path in terms of path planning,because the traditional Genetic algorithm has the disadvantage of premature convergence and slow convergence.In this paper,the crossover and mutation operation of genetic algorithm is improved and the algorithm is realized by Java programming.The feasibility and effectiveness of the improved algorithm is proved.Finally,based on the analysis of the current situation of distribution and distribution of agricultural products in Fuyang City,this paper uses GIS's spatial analysis function topre-select the candidate points according to the location model of distribution center,and then use the analytic hierarchy process to determine logistics distribution center final position.On this basis,the development of agricultural products logistics and distribution system platform to achieve logistics and distribution information,the application shows that: the system is stable,simple,practical.The content of the thesis is of great significance to the comprehensive benefit of agriculture,which is of great practical significance to the construction of a conservation-oriented city.
