[Indexing system and its quantitative expression for soil quality evaluation in Hainan Island].
Based on the SOTER database and some FAO frameworks, a soil quality indexing system was established, and some evaluation results were presented for some selected GIS photo spot of tropical cropland in Hainan island. With connection to the spatial database, this system could perform the output of evaluation results. The performance and evaluation results were approved by the local expertise. It is suggested that the established models should be modified by the local practice.
