英文摘要	An effective evaluation of soil fertility can provide a theoretical basis for managing quality and strategies of fertilization for soil. Based on 32 m × 32 m grid sampling, the soil organic matter, total N, total P, total K, available K, available P, salinity and soil pH were used as the soil fertility evaluation factors. And we integrated evaluation of the soil fertility using classical statistics, geostatistics and modified Nemoro fertility index. The result shows that the mean value of pH was 8.89 which showed alkalinity. The CV for organic matter, total N, total K, pH and available K were low variation. Others (total P, available P and salinity) were moderate variation. The nugget variances for organic matter and total were strong spatial autocorrelation. Others were between 0.418 and 0.5, indicating moderate spatial autocorrelation. The spatial distribution of each fertility index was not obvious. The Ps was within the range of 0.63–0.80, all fertility indicators surrounding graphics areas were small in Radar map, indicating the fertility level was classified as barren. The mean fertility index, Pi, of the soil was in the order: available K > salinity > total K > available P > pH > total P > organic matter > total N. The soil organic matter and total N were the main limiting factors restraining soil fertility. The spatial distribution patterns of soil index and Ps were complicated and had no regularity with patch distribution at field scale. The methods of increasing organic fertilizers, crop rotation and fallow were practicable and necessary for soil fertilizing management, increasing yields and improving crop quality. © 2019, NAAS (National Academy of Agricultural Sciences).
