This paper deals with the application of the 3S technique to the management of crop residue burning,

which includes the general principle and method of data processing as well as the results of the monitoring of crop

residue burning. The RS technique is used to monitor the hot spot caused by crop residue burning and determine the

harvest period. The GIS technique is employed to determine the nature of the hot spot and analyze the condition of

crop residue burning, whereas the GPS technique is adopted to find the exact location of the hot spot caused by crop

residue burning detected by the RS technique. The general situation of the application of this technique to this

field in recent years is also recounted in this paper.
