The result showed that the area of the middle and low-yielding farm- land in Nuanquan farm was 4 325 hm2, accounting for 90.8% of total farmland in Nuanquan farm. Among it the area of the obstacle hierarchical type, the barren and thin and waiting to be fertilized type and saline-alkali land type account for 47.3%, 35.2% and 17.5% of the total middle and low-yielding farmland respectively.
