珠江三角洲地区空气自动监控网络数据空间模拟适用方法

珠江三角洲地区已构建起区域性空气质量自动监测网络,由于初步建立的自动监控网络监测站点对整个区域而言极其有限,如以单离散数据形式发布则不能反映出区域空气污染的连续变化特征和全貌.对有限点位监测结果进行空间模拟研究才能满足反映区域性污染状况的需求.通过运用、比对、评价不同空间插值模型于自动监控网络离散站点的模拟应用,提出了珠江三角洲自动监控网络数据空间模拟适用方法.

Applicability Research on Spatial Modeling Methods for PRD Air Automatic Monitoring Data

An air quality automatic monitoring network has been constructed in Pearl River Delta Region(PRD).At the beginning stage,the number of monitoring sites is quite limited.Pure discrete data publishing method can not reflect the regional air pollution character for easy public understanding.It is necessary to find out suitable spatial modeling methods to visualize the monitoring result from the limited sites for data publishing purpose.By applying,comparing and assessing different spatial interpolation methods on discrete automatic monitoring sites,the study presents an applicability analysis method for choosing suitable spatial modeling methods for the PRD air automatic monitoring network.
