Design And Implementation Of Information Management System Of The Nature Reserve Of Dangshan Pear

Precision management of orchard is an important research topic of precision agriculture.Precision agriculture technology has been carried out multi-level and multi angle researches at home and abroad.But there are some differences in precision management between orchard and agriculture,and there are still a lot of problems to be solved in precision orchard technology.The orchard production management has its own characteristics,especially in the Provincial Nature Reserve of Dangshan pear.In order to improve the quality of the precision management of the orchard,the Provincial Nature Reserve of Dangshan pear is taken as the research object and an in-depth analysis of the requirements was carried out.Finally the orchard resources information management system was designed and developed by using information technology,GIS and fuzzy preference model.The main contents include:1.Based on the requirement analysis of Dangshan Pear Nature Reserve,the overall structural design of the system was completed.Firstly,according to the status of protection and the distribution status of Dangshan pear,a survey of Dangshan pear germplasm resources was made.Then,with the help of Beidou single base station tools,the relevant information of hundred years old pear trees was collected.Finally,a basic database of resources information of the nature reserve was established,and based on the database,the resource information management system of Dangshan pear nature reserve is designed.2.Based on system requirements and user requirements,a recommendation method based on user fuzzy preference relationship was constructed.Firstly,according to the actual needs of Dangshan Pear Nature Reserve,the classification of user groups and the classification of items in the Dangshan pear nature reserve were determined.Then,the user preference data was collected through questionnaires,and accordingly a fuzzy preference relationship model was constructed.Finally,based on the spatial navigation and positioning data and survey data as data support,recommendation results according to different roles were given and analyzed to verify the feasibility of this recommendation method.3.Based on the requirement analysis and the system design,the system was implemented and successfully applied in the Dangshan Pear Nature Reserve.The functions of the system includes digitization of resources in Dangshan Pear Nature Reserve,precision management of pear gardens,and information recommendation functions based on user preferences.This system improved the management level of Pear Garden in terms of information management and auxiliary decision-making capabilities.It also plays important roles for protected area resources,especially precious ancient fruit trees and improving the utilization rate of agricultural resources in orchards.The research has good application value to precision orchard.
