摘要

针对耕地质量分级与地球化学评价成果整合中的权重确定问题，提出了通过分析误差变化来确定权重取值范围的搜索方法。本文以吉林省西部某县为例，对该方法进行了验证。结果表明，研究区权重的合理取值范围为[0.7,0.9]。

Notice of RetractionA Method of Weight Determination in Integration of Cultivated Land Quality Classification and Geochemical Assessment

Aiming at the weights determination in the integration of cultivated land quality classification and geochemical assessment achievements, this paper puts forward the searching method to determine weights value range by analyzing the changes of errors. This paper verifies the searching method in a county of west part in Jilin Province. The results indicate that the reasonable value range of weight is [0.7,0.9] in the research region.
