| Abstract: |
| 【Objective】The information platform of saline soil improvement technology integration was constructed,aiming to improve saline soil to provide for information services and decision.【Method】Taking Weinan region for study object,Java2 Platform-Enterprise Edition (J2EE) technology,Remote Sensing,Geographical information System,Global Positioning System (3S) integrated technology,Adcanced Application Framework (AAF) technology,database technology and wireless communication technology were used to construct,the information platform of saline soil improvement technology integration was built,and its main functions were analyzed.【Result】The information platform of saline soil improvement technology integration was designed and built,the platform can be the real-time monitoring for saline soil and the evolution of space-time dynamics for soil saline distribution.Through the real-time monitoring and the evolution of space-time dynamics,according to saline change,distribution and features,improvement technologies can be filtered and recommended,and the platform also has a wireless application system-information service of WAP mobile portal,so application data and information can be visited by wireless handheld devices.In addition,the platform also can reflect time-space evolution function of the saline soil in different regions.【Conclusion】The information platform of saline soil improvement technology integration is feasible.It can visualize and modernize the application of saline soil improvement technology integration,and achieve monitoring of soil salinization and direct guidance of integrated technologies for saline soil improvement,the platform can provide timely and reliable technology information security to saline soil management and agriculture sustainable development. |
