摘要
传统的大气环境污染估算模型主要考虑热力因子,计算虽然相对简单,但是忽略了大气污染点源扩散模式的研究,所以存在估算不够准确的问题。针对以上问题,利用地理信息系统的数据监测,数据管理及数据查询与输出功能,通过对影响大气环境的污染因素及其扩散模式进行分析,运用模糊矩阵法构建出用于估算大气环境污染的模型,并通过实验分析,表明该模型在数据处理估算方面都有明显的优越性,能够为大气环境污染估算提供更加准确的估算结果。
The traditional estimation model of air pollution generally ignores the factors of air pollution diffusion,and the calculation process is complex,lading to inaccuracy.By using the data monitoring,data management and data query and output functions of GIS,the fuzzy matrix method is used to build a model for the estimation of atmospheric environmental pollution through the analysis of the factors affecting the atmospheric environment and its diffusion mode.The experimental results show that the model has obvious advantages in the accuracy of data processing and estimation,and can be used to air pollution estimation for more accurate results.
