模糊多层次综合评判在土地定级中的应用

Fuzzy Multi-levels Comprehensive Evaluation and Its Application in Land Grading

运用模糊数学理论 ,建立了土地定级模糊多层次综合评判的数学模型 ,合理确定土地定级各影响因素及其子因素的权重 ,把定性分析和定量计算有机结合起来 ,使土地定级建立在主客观统一的理论基础上 ,增强了土地定级的准确性和可靠性。

Form the angle of Fuzzy Mathematics,the author makes the mathematic model of the land grading by using the fuzzy multilevels comprehensive evaluation.This method combines the qualitative analysis with the numerical calculation and makes the land grading based on the unity of subjective and objective theory .As a result it raises the accuracy and the reliability of the land grading.
