摘要
Abstract
Spatial attributes of cropland patches were set as natural grade,utilization grade and economic grade of cropland quality assessment.With local spatial auto-correlation method,the spatial distribution of cropland quality was analyzed and the characteristic of spatial distribution and the rationality of results of cropland quality assessment were discussed.The results showed that significant aggregation was one of the characteristics of cropland quality of Jilin Province.HH and LL types were positive correlation and the distribution characteristics were aggregated.HL and LH types were negative correlation and the distribution characteristics were scattered.Through analyzing the rationality of the results of cropland quality assessment,the method and the results of this study can be used to support the update assessment and management of cropland quality in the future.关键词
