利用层次分析法和隶属函数建立土地质量地球化学评估模型，对河北省尚义县坝上地区土地质量进行地球化学评估。结果显示：评估区土地质量整体良好，土壤一等面积比例为22.65％，营养元素和健康元素含量均较高，二等面积比例为40.65％，三等面积比例为6.80％，F-、Cl-含量高，盐碱化严重；灌溉水一级面积比例为64.30％，二级面积比例为35.70％，影响灌溉水级别划分的主要指标为F-和Cl-，超标比例分别为5.70％和34.30％；土地质量二等一级（21）和一等一级（11）所占比例较大，分别为40.65％和22.65％，三等二级（32）和三等一级（31）所占比例较小，分别为1.60％和6.80％。

The land quality in Bashang plateau of Shangyi County,Hebei Province is evaluated on geochemistry using land quality geochemical assessment model which is built using the analytic hierarchy process and mem-bership functions.The results indicate that the land quality of assessment area is in good condition.The soil of the first quality grade is rich in nutrient elements and health indicators which accounts for 22.65%in the whole region,the proportion of second quality grade area is 40.65%,the proportion of third quality grade area with high of F-and Cl-is 6.80%,which has serious soda saline land.The irrigation water of the first and second quality grade accounts for 64.30%and 35.70%.The main influencing factors of irrigate water division are F-and Cl-,the over standard proportion of which are 5.70%and 34.30%.The 2 1 and 1 1 in geochemical assess-ment class and grade have a larger proportion,which accounts for 40.65%and 22.65%,relatively,the 32 and 3 1 with lower rate accounts for 1.60% and 6.80%.
