The coupling of GIS and ANN is used to early warning of the salinazation in west Jinlin plain. The spatial correlation coefficients
soil texture
the content of organic matter
the content of Na+
the population density and the number of livestock are selected as factors for salinzation early warning. The result shows that the non warning area covers 20.12% of the total area
