海南岛土壤质量的指标与量化表达研究

Indexing system and its quantitative expression for soil quality evaluation in Hainan island.

在海南岛SOTER数据库基础上 ,结合联合国有关原则与规定 ,选取表征土壤质量的若干指标项目组成体系 ,在GIS环境中对图斑的土壤质量进行评价 ,并将评价等级指数与空间数据库相连 ,根据用户需求将土壤质量的评价结果输出 ,结果得到当地有关专家的认可 .建议通过当地实践结果 ,对模型进行必要的修订 (适当修改评价指标及量化标准 ) ,使之更趋完善 .

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.
