摘　　要：在分析突发性土壤污染事故的特点和应急监测业务流程的基础上,归纳了应急监测方案中涉及到的空间技术问题,并提出了基于地理信息系统(GIS)的空间问题解决方案。该方案综合运用GIS中的空间数据管理、查询、分析、可视化等手段使应急监测中的事故定位、数据监测等工作更加合理有效。同时,针对污染监测数据的特点,集成了污染评价模型,并研究了空间插值、空间叠加、空间统计等GIS分析技术在污染监测与模拟数据可视化表达上的应用。结果表明,相对于传统的应急监测手段,GIS技术的应用更有利于突发性土壤污染事故的响应和处理。After analyzing the features of sudden soil pollution accidents and business processes of emergency monitoring,this paper summed up the spatial technical problem involved in the emergency monitoring program and raised the GIS-based solutions of spatial problem.The program applied GIS spatial data management,query,analysis and other means into emergency monitoring process,so that the location of accident,data monitoring and other work could be more reasonable and effective.At the same time,in connection with the characteristics of pollution monitoring data,the program integrated pollution assessment model and studied the using of GIS analysis technology such as spatial interpolation,spatial overlay,spatial statistics in pollution monitoring and stimulant data visualization.The results show that compared with traditional means of emergency monitoring,the application of GIS technology can help to respond and handle sudden soil pollution accidents.
