Crop Production Control Information System Construction Based On WebGIS

China is a developing country.It remains the foundation of our national economy in China,and in a predominantly agricultural country,the national economy depends largely on whether the development of agriculture.However,at present,there are some problems in the traditional agricultural production process.Such as low level of farmer knowledge,planting more by empiricism,pest and disease agents is not standardized,middle income and low efficiency,poor quality of crops and so on.It seriously restricting the rapid development of China's agriculture and directly affect the international competitiveness of agricultural exports in the field.Furthermore,as the complexity of production,crop production management decisions become increasingly difficult.Now along with the rapid development of Information technology and GIS technology, how to use advanced information technology tools to develop crop production management system for guiding farmers production, and Providing the government's decision support is the urgent need to resolve important issues.This study used a software engineering development method,Used of WebGIS, J2EE technology,ArcSDE spatial database technology,and J2ME technology,based on Shandong Shouguang crops' information data, For the purpose of the management requirements of modern agricultural production,Combined relevant research results to develop WebGIS-based management information system of crop production in Shouguang.And extended GIS services to the field,using mobile phone remote to supervise agricultural production activities. Considering the system of crop production activities and the actual needs of government supervision,Divided into four categories for the user permissions Login,and different users can only use its authority under the functions of the corresponding. System designed five major functional modules,Users can get services through the system such as Base Map View,Crop information inquiry,production cycle control,fertilizating and watering guide,transport process monitoring,remote wireless service,production support and so on.Firstly,the study background of agricultural information,digital agriculture,precision agriculture and other agricultural development were briefly discussed,the significance of the subject topics were pointed out, explained the purpose, content, analyzed GIS technology at home and abroad in the field of agricultural development status and specific applications, summarized some existing deficiencies and shortcomings in the current application, proposed crop production management based on WebGIS platform, and discussed the contents and ideas.Secondly, core technology in the System development process has been overviewed.Presented the technical features and advantages of WebGIS, Geodatabase data model, and ArcSDE operating mechanism. Described the use of the advantages of J2EE and J2ME technology, laid the foundations of system design and implementation.Based on sysytem design, designed specific function modules of the system, described the process of spatial database design and construction,and the system functions realization method.Finally, based on the main features of the system, the system key technology and innovation idea were brought forward,the problems and shortage was pointed out, and further improvement of the system suggestions were prospected.
