基于遥感的桂林空气监测点位优化布设研究

Research on Air Monitoring Sites Optimization Layout Based on Remote Sensing in Guilin

采用空间分析的思想指导监测网络的优化布点设计,在充分考虑污染物空间相关性与空间变异性的基础上,引入最小克里金方差的评价准则,以监测站点对未知点的插值方差作为监测网络对该点代表性的量化依据。以桂林市为研究区,PM_(10)的遥感影像反演结果作为先验知识,对已有监测网络进行评价并提出优化的设计方案。

This paper adopted the thought of spatial analysis to guide the optimal layout design of monitoring network. In order to make the monitoring of the unknown difference variance of monitoring site as the monitoring network for the quantitative basis of this monitoring site, based on the spatial correlation and spatial variability of pollutants fully, the paper imported the minimum Kriging variance as the evaluation criterion. Taking Guilin City as the research area, PM_(10)'s remote sensing inversion results as prior knowledge, the paper evaluated the existing monitoring network, and optimized the design program.
