摘要
开发利用盐碱地是补充耕地、保障国家粮食安全的重要途径。加强水盐动态监测是掌握水盐运移规律,及时采取针对性调控措施改良利用盐碱地的基础。本文基于WebGIS平台,采用微软Silverlight技术,设计开发了盐碱地水盐动态监测系统,实现了地块信息查询、水盐数据统计分析、水盐空间分析、水盐动态趋势分析及预警等功能,并在山东省无棣县盐碱农田进行了应用。结果表明,该系统可以辅助用户及时、全面掌握盐碱农田水盐动态信息,为田间管理提供决策支持。
The exploitation and utilization of saline-alkali land is an important way to supplement cultivated land and ensure national food security. Strengthening the dynamic monitoring and mastering the movement law of water and salt are the bases of taking measures timely to improve the utilization of saline-alkali land. Based on the WebGIS platform and Microsoft Silverlight technology, a dynamic monitoring system was designed and developed for salt and water in saline-alkali land. The system realized the functions such as field parcel information query, statistical analysis, spatial analysis, dynamic trend analysis and early warning, and the system was applied in the saline-alkali land in Wudi County of Shandong Province. The results showed that the system can assist users to grasp the dynamic information of water and salt in saline-alkali land timely and comprehensively, thus can provide decision support for field management.
