摘　　要：以新疆加工番茄某主产区试验田的15个土壤样本为试材,利用层次分析法(Analytic hierarchy process,AHP)和熵权法分别得到主、客观权重,再运用博弈论思想将权重组合,进而采用组合权重赋权的Dtopsis(Dynamic technique for order perference by similarity to ideal solution)法对试验区不同地块土壤肥力进行评价。结果表明:得到15个样本直观的优劣排序结果,符合生产实际,为精准施肥及作物种植规划提供指导。The Dtopsis（ Dynamic technique for order perference by similarity to ideal solution） based on combination weighting was used to valuate soil fertility for processing tomato in Xinjiang region according the15 soil samples from a testing field.The analytic hierarchy process and entropy method were respectively used to get the subjective and objective weights combined by the game theory.The intuitive results reflect the actual situation.This method was feasible and scientific,which could provide reference for precision fertilization and crop planting.
