摘要
秸秆焚烧会产生大量污染物,对大气环境、气候以及生态模型产生重要影响,文章通过MODIS遥感卫星数据,使用关系型数据库(Access)管理数据,基于高斯烟羽扩散模型和ArcGIS Engine开发相应的功能,利用C#.NET和GIS二次开发技术,实现气体污染情况模拟系统的设计与开发。系统以一个栅格像元为单位,利用高斯扩散模型计算出火点周围的污染物浓度,并将最终气体浓度值和扩散范围在GIS平台上的可视化表达。为当地居民提供预警,加强防范措施。
Straw incineration will produce a large number of pollutants,which will have an important impact on the atmospheric environment,climate and ecological model.This paper uses MODIS remote sensing satellite data,with relational database(Access)for managing data,develops corresponding functions based on Gaussian plume diffusion model and ArcGIS Engine,and uses C#.NET and GIS secondary development technologies to realize the design and development of gas pollution simulation system.The system takes a grid pixel as a unit,uses the Gaussian diffusion model to calculate the pollutant concentration around the fire point,and visually expresses the final gas concentration and diffusion range on the GIS platform,so as to provide early warning for local residents and strengthen preventive measures.
