基于WebGIS的耕地质量预警系统

摘要

为防止耕地质量状况继续严重恶化，提高粮食产量，借鉴国内外已有耕地预警理论最新成果，收集和处理相关图件和土壤养分数据，确定技术流程、设计系统结构、构建指标体系、选取预警预测模型和设计系统功能，最终基于 WebGIS 平台建立了耕地质量预警系统。并以肥东县为例，确定了预警单元耕地质量，实现了对耕地肥力的实时警报和预测。%For preventing farmland degenerating and increasing food production, this research used some theories and practices of early-warning both in home and overseas for reference. This paper collects and processes datum, designes technical flow and system structure, builds index system, chooses the early-warning models, and implements system function. Finally, the cultivated land quality early-warning system was proposed based on WebGIS. Using Feidong as an example, cultivated land capability class was established and cultivated land fertility was predicted.
