5. CONCLUSIONS
The GIS-based approach for predicting the spatial distribution of soil salinization is promising method widely
accepted. The ability to predict the salinazation potential provides an invaluable tool for agricultural management
purposes. It can serve as a mean of monitoring the salinity and to assist in formulating the allocation of the budget
plan for salt reclamation. To minimize the impact of salinity on the agricultural land, with the spatial information
the testing experiment for the reclamation should be located. A very complicated and dynamic phenomena of the
soil salinization in the Northeast should be a long term study and made available to publics. A watershed approach
to the management of salinity should be taken particularly the reforestation in the upstream areas. This is to lower
ground water in the down stream areas. On locations of salinity previously developed, consideration of the water
use and balance should be undertaken to minimize the movement of the soluble salt from the lower strata to soil
surface. The development of water sources should be considered carefully and avoid construction in vulnerable
areas.
