This paper outlines the basic Atmospheric Diffusion Models (ADM) and integrated models which are based on the principle of selecting models in CZEMIS. The principle of software engineering is adopted to make the structure design for ADM and a software package is established. The pollutant distribution for different metereological conditions, different location and emitting feature of pollution sources, and the average of different period can be obtained with the help of the package.

This paper outlines the basic Atmospheric Diffusion Models (ADM) and integrated models which are based on the principle of selecting models in CZEMIS. The principle of software engineering is adopted to make the structure design for ADM and a software package is established. The pollutant distribution for different metereological conditions, different location and emitting feature of pollution sources, and the average of different period can be obtained with the help of the package. This package can also be used to examine the accuracy of models, adjust parameters, and give graphics to indicate the pollutant distribution.

本文根据常州市环境管理信息系统(CZEMIS)合理选择大气扩散模式的基本原则,概述了大气扩散的基本模式,并对基本模式进行有效的合成。利用软件工程思想对大气扩散模式进行结构化设计,形成大气环境质量预测软件。

Through the conclusion and analysis on the production technology process in the foundy shops, it is considered that the feature of pollution is that the pollution spots are in great number and dispersive. And the main source is the first the charging material and the second the moulding material In case a simple matlematic calculation is carried out, and the relation between the adding amount of powder material and the enviroment pollution is concluded, tackling approaches would be presented...

通过对铸造车间生产工艺过程的总结分析,认为污染的特点是:污染点多而分散;主要根源一是炉料二是造型材料。如经过简单的数学运算,归纳出粉状材料加入量与车间环境污染的关系。依据数学模型,有针对性地提出治理的方法。

ased on the monitoring and predictive analysis of atmospheric pollutants, the clustering analytic method and synthetic index method were used to classify the POllution areas into four types and to classify the greening vegetations into three types in terms of the size of index value. Then further based on the features of POllution for each type of POllution areas, corresponding afforestation models and plant species were selected to green the areas in order to improve the atmospheric environmental...

ased on the monitoring and predictive analysis of atmospheric pollutants, the clustering analytic method and synthetic index method were used to classify the POllution areas into four types and to classify the greening vegetations into three types in terms of the size of index value. Then further based on the features of POllution for each type of POllution areas, corresponding afforestation models and plant species were selected to green the areas in order to improve the atmospheric environmental quality there. The study demonstrates that more serious single and comPOunded pollutions generally took place at 300 to 4000m leeward from pollution sources, where an afforestation model consisting of the proper combination of arbor,bush and grass was better in improving the quality of atmospheric environment.

在大气污染物实测和预测分析的基础上,应用聚类分析和综合指数的方法将污染区分为4个类型,绿化植物按照指数大小划分为3类。根据每个类型污染特点选择相应的绿化模式和植物种。研究表明:距污染源下风向300—4000m是重污染区,单一污染和复合污染在该范围内较严重。绿化模式以乔、灌、草结合的形式对大气污染净化效果较好。
