基于粗糙集和信息熵的土地适宜性评价研究

Study on Land Suitability Evaluation Based on Rough Set and Entropy

将信息熵理论与粗糙集技术引入土地适宜性评价领域,通过计算指标的信息量,为指标权重的确定提供科学依据,从而有效地避免指标权重确定过程中的主观性。通过福建省武平县城乡建设用地适宜性评价的实际应用进一步验证该方法的有效性,为土地适宜性评价开拓一种新的思路。

The rough set method and information entropy method were introduced to land suitability evaluation by computing information of evaluate index,so as to provide scientific basis for the establishment of evaluate index weights.It could effectively avoid the subjectivity in the process of establish evaluate index.Taking the model to evaluate the rural-urban construction land use suitability in Wuping County,and reflect the scientific rationality of the evaluation index system model,it also provided a new way for land suitability evaluation
