Site index estimation based on geostatisics combined with GIS.

LIU Yong-xia;FENG Zhong-ke;YAO Shan.Institute of GIS,RS &GPS,Beijing Forestry University,100083,P.R.China.  
In order to obtain the territorial site index distribution map which is advantageous for the inquiry and analysis,geoestatisitics combined with GIS was applied to estimate site index.The research based on Kriging method was done by Arcview space analysis modular.The research shows that GIS,with the combination of geostatisitics(Kriging),by using the limited sampling data,can estimate the lack data accurately and quickly and obtain the entire forest site index distribution map.With this distribution map people can get corresponding location,look over results visually and carry out corresponding analysis.Geostatisitics technique was applied to estimate site index successfully,its estimated value had no deflection and had minimum variance.
