摘要
探讨了土壤质量时空变化一体化的评价方法 ,并以河北省曲周县一个 3 3km2 的小区为例 ,对 1980年与 1999年两个时段的 8个单项土壤质量指标和土壤综合质量指标的时空变化进行了定量化评价。结果表明土壤质量指数法与GIS技术相结合 ,可以很好地表示土壤质量的时空变化。文章还讨论了该方法的适用范围。
Studying spatial temporal changes of soil-quality is of significance to sustainable soil management.This paper mainly deals with an assessment method of soil quality: space-time changes with GIS spatial analysis function. A small area located in Quzhou County of Hebei province was chosen as a case area and we assess the changes of soil quality and the soil properties between 1980 and 1999. Eight indicators were used for soil quality index.The results indicated that this method is feasible in the plain areas where land use types are not enormously different.At last,the limitations and improvement of this method were discussed.
