ZOU Yue,FAN Yi,ZHENG Hong-gang,YU Jian-xin(College of Water and Construction,Yunnan Agricultural University,Kunming 650201,China)  
Since"Regulations for classification on agricultural land"had not taken altitude factor into account as grading factors,Shangri-La County in Yunnan province were taken as the example,using standard grain yield to analyze the influence of altitude factor on natural quality of agricultural land,and altitude factor was taken as a coefficient into the computation of parameters as natural quality.The results showed that the outcomes accorded with actual situation very well when altitude factor taken as a coefficient into the computation of parameters as natural quality.It is suggested that this method can be used at those areas where altitude discrepancy is big,three-dimensional climate is obvious and farmlands distribute at various altitudes to modify the influence of altitude on parameters as natural quality of agricultural land in the grading of agricultural land.
