泰森多边形在环境空气监测网络布设中的应用

Thiessen Polygon and Its Application in Planning of Ambient Air Monitoring Network

泰森多边形是由荷兰气候学家A.H.Thiessen提出的一种由点到面的内插方法,最初应用在气象观测中,近年来该方法在环境监测中得到了应用。本文介绍了泰森多边形的原理、算法以及其在环境空气监测网络布设中的应用。

Thiessen polygon was created by A . H. Thiessen, a meteorologist of the Netherlsnds, which is an approach to inter-polating areas from points. Although it was applied in meteorological observation initially, it has been expanded to environmen-tal monitoring in recent years. This paper introduces the principles and the algorithm for its implementation of Thiessen poly-gon, and then illustrates its applications in planning of ambient air monitoring network.
