%X This paper studied the chemical, physical and biological properties of newly cultivated light sierozem by field experiment and lab analysis, 10 indexes were selected and the methods of principal component and cluster analyses were used to evaluate soil fertility quality. The results showed that soil fertility quality of sierozem improved after cultivation, irrigation and crop-planting, and the application of organic manure or combined with chemical fertilizers could improve soil fertility quality of sierozem more effectively.
