The PM2.5 Prediction In Kunming Base On Kriging Interpolation Method

Kriging interpolation method is by the South African mining engineer kriging in 1951 when looking for a gold mine by using partial differential method for the first time.There are the perfect theoretical foundation at present,and it is practical application in many fields,such as detection of mineral, the distribution of precipitation, soil pollution, the content of particles in the air, and so on.With the development of the society,the progress of humanity and the human pursuit of quality of life,air quality problems caused the human more and more discussion.One of the important indicators of the air quality is PM2.5,also received widespread attention.This article system steps and tasks on the kriging interpolation method,The key to study the effect of spatial distribution of air quality.This article introduces the relevant theories of kriging interpolation method. At the same time, in order to use kriging interpolation method, the article introduces the detailed data for research. This article structurally, firstly introduces an overview of inverse distance weighting method; secondly, introduce the basis of statistics -- half the variation function; thirdly focusing on various kriging interpolation method of related theory and proof;finally, combining with the actual PM2.5 data in kunming, using R language to solve kriging interpolation method.
