基于WebGIS的畜禽养殖废弃物对农田环境污染预警系统研究

摘要

[目的]为了快速、实时动态地获取区域内畜禽养殖废弃物对农田环境污染情况。[方法]以WebGIS为空间信息平台,构建了网络化、数字化的畜禽养殖废弃物对农田环境污染预警系统。[结果]系统主要实现了畜禽养殖废弃量计算、畜禽养殖相关信息查询与分析、农田畜禽养殖废弃物氮负荷量估算、畜禽养殖废弃物对农田环境污染预警及结果可视化输出等。[结论]该研究可为畜禽废弃物对环境污染的相关研究提供科学依据。%[Objective]The paper was to quickly get the real-time dynamic status of regional farmland environmental pollution caused by livestock wastes.[Method] With WebGIS as spatial information platform,the network and digital early warning system of farmland environmental pollution caused by livestock wastes was established.[Result] The system realized the functions such as livestock wastes calculation,livestock information query and analysis,nitrogen load quantity estimation of livestock waste,early warning of farmland environmental pollution caused by livestock wastes and visual display of result.[Conclusion] The paper provided scientific basis for the relevant research on farmland environmental pollution caused by livestock wastes.
