摘    要:选取湖南省岳阳市为研究对象,利用PSR模型构建岳阳市土地可持续利用评价指标体系,在对指标值进行标准化的基础上,采用改进熵值法确定指标权重,最后计算岳阳市土地可持续利用程度。结果表明,岳阳市土地可持续利用水平在2005-2014年总体处于较高层次,但中间年份由于自然原因和社会经济原因,导致岳阳市土地可持续利用水平出现较小波动;岳阳市土地可持续利用水平与岳阳市自然条件、岳阳市城市的建设机遇及政府的建设态度相关。

关 键 词:PSR模型  改进熵值法  土地可持续利用  评价  岳阳市

Abstract:Taking Yueyang city in Hunan province as the research sample,the evaluation index system was constructed by using PSR as a model.After standardizing the index value,the weight was counted by entropy evaluation method and the score was got on this bases.The results showed that the evaluation score of land sustainable use of Yueyang from 2005 to 2014 was at a superior class,but there was minor changes in some years because of the natural and socioeconomic factor.The evaluation score of land sustainable use of Yueyang had strong connection to its natural condition,development opportunity and the govermnent's attitude.
Keywords:PSR model  improved entropy evaluation method  land sustainable use  evaluation  Yueyang city
